CVE-2019-3572 | 2019-01-02T15:29:00.330 | An issue was discovered in libming 0.4.8. There is a heap-based buffer over-read in the function writePNG in the file util/dbl2png.c of the dbl2png command-line program. Because this is associated with an erroneous call to png_write_row in libpng, an out-of-bounds write might occur for some memory layouts. | {

- [x] I have written a descriptive issue title
- [x] I have verified that I am using the latest version of ImageMagick
- [x] I have searched [open](https://github.com/ImageMagick/ImageMagick/issues) and [closed](https://github.com/ImageMagick/ImageMagick/issues?q=is%3Aissue+is%3Aclosed) issues to ensure it has not already been reported
### Description
<!-- A description of the bug or feature -->
memory leak in WritePSDChannel in coders/psd.c
### Steps to Reproduce
<!-- List of steps, sample code, failing test or link to a project that reproduces the behavior.
Make sure you place a stack trace inside a code (```) block to avoid linking unrelated issues -->
The critical code snippet is:
https://github.com/ImageMagick/ImageMagick/blob/master/coders/psd.c#L2767
```c
#ifdef MAGICKCORE_ZLIB_DELEGATE
if (compression == ZipCompression)
{
compressed_pixels=(unsigned char *) AcquireQuantumMemory(CHUNK, //line 2770
sizeof(*compressed_pixels));
if (compressed_pixels == (unsigned char *) NULL)
{
quantum_info=DestroyQuantumInfo(quantum_info);
return(0);
}
memset(&stream,0,sizeof(stream));
stream.data_type=Z_BINARY;
level=Z_DEFAULT_COMPRESSION;
if ((image_info->quality > 0 && image_info->quality < 10))
level=(int) image_info->quality;
if (deflateInit(&stream,level) != Z_OK) //line 2782
{
quantum_info=DestroyQuantumInfo(quantum_info);
return(0); //line 2785
}
}
```
**compressed_pixels** is allocated at *line 2770*, however, when the condition at *line 2782* is satisfied and the function returns at line *2785*, **compressed_pixels** (size is 16KB) is not freed and memory leak happens. In addition, the value of **compressed_pixels** is not passed outside to its caller function when returned at *line 2785*.
So the condition that this memory leak happens is that *MAGICKCORE_ZLIB_DELEGATE* is defined, compression type is *ZipCompression* and *deflateInit(&stream,level)* is not *Z_OK*. The size of leaked memory is 16KB.
Patch suggestion:
```c
if (deflateInit(&stream,level) != Z_OK) //line 2782
{
quantum_info=DestroyQuantumInfo(quantum_info);
+ compressed_pixels=(unsigned char *) RelinquishMagickMemory(
+ compressed_pixels);
return(0);
}
}
```

### Description
<!-- A description of the bug or feature -->
potential memory leak in ReadSIXELImage in sixel.c
### Steps to Reproduce
<!-- List of steps, sample code, failing test or link to a project that reproduces the behavior.
Make sure you place a stack trace inside a code (```) block to avoid linking unrelated issues -->
The first critical code snippet is:
https://github.com/ImageMagick/ImageMagick/blob/master/coders/sixel.c#L539
```c
if (imsx > max_x || imsy > max_y) { // line 539
dmsx = max_x;
dmsy = max_y;
if (SetImageExtent(image,dmsx,dmsy,exception) == MagickFalse)
{
imbuf = (unsigned char *) RelinquishMagickMemory(imbuf);
return (MagickFalse);
}
if ((dmbuf = (unsigned char *) AcquireQuantumMemory(dmsx , dmsy)) == NULL) { //line 547
imbuf = (unsigned char *) RelinquishMagickMemory(imbuf);
return (MagickFalse);
}
for (y = 0; y < dmsy; ++y) {
(void) memcpy(dmbuf + dmsx * y, imbuf + imsx * y, dmsx);
}
imbuf = (unsigned char *) RelinquishMagickMemory(imbuf);
imsx = dmsx;
imsy = dmsy;
imbuf = dmbuf; //line 557
}
*pixels = imbuf; //line 560
*pwidth = imsx;
*pheight = imsy;
*ncolors = max_color_index + 1;
*palette = (unsigned char *) AcquireQuantumMemory(*ncolors,4); // line 564
if (*palette == (unsigned char *) NULL)
return(MagickFalse); // line 566
```
When condition at line **539** is satisfied and **dmbuf** is successfully allocated at line **547**, the value of dmbuf is assigned to **imbuf** at line **557** and is finally assigned to the pointer parameter **pixels** at line **560** (i.e. the buf's address is passed outside to the caller function).
Now, when the allocation at line **564** failed, the function will return *MagickFalse* at line **566**.
Next, I searched the whole project code and only found one call to **sixel_decode** which locates in function **ReadSIXELImage** in sixel.c at line **1057** as the following. The local variable **sixel_pixels** holds the value of **dmbuf**.
https://github.com/ImageMagick/ImageMagick/blob/master/coders/sixel.c#L1057
```c
if (sixel_decode(image,(unsigned char *) sixel_buffer,&sixel_pixels,&image->columns,&image->rows,&sixel_palette,&image->colors,exception) == MagickFalse) // line 1057
{
sixel_buffer=(char *) RelinquishMagickMemory(sixel_buffer);
ThrowReaderException(CorruptImageError,"CorruptImage");
}
sixel_buffer=(char *) RelinquishMagickMemory(sixel_buffer);
image->depth=24;
image->storage_class=PseudoClass;
status=SetImageExtent(image,image->columns,image->rows,exception);
if (status == MagickFalse)
{
sixel_pixels=(unsigned char *) RelinquishMagickMemory(sixel_pixels); // line 1068
sixel_palette=(unsigned char *) RelinquishMagickMemory(sixel_palette);
return(DestroyImageList(image));
}
```
However, when function *sixel_decode* returned *MagickFalse* as described above, the memory pointed by **sixel_pixels** (i.e. the memory allocated at line 547) was not freed as done at line **1068**. As a result, a memory leak happens.
Patch Suggestion:
```c
if (sixel_decode(image,(unsigned char *) sixel_buffer,&sixel_pixels,&image->columns,&image->rows,&sixel_palette,&image->colors,exception) == MagickFalse)
{
sixel_buffer=(char *) RelinquishMagickMemory(sixel_buffer);
+ sixel_pixels=(unsigned char *) RelinquishMagickMemory(sixel_pixels);
ThrowReaderException(CorruptImageError,"CorruptImage");
}
```

- [x] I have written a descriptive issue title
- [x] I have verified that I am using the latest version of ImageMagick
- [x] I have searched [open](https://github.com/ImageMagick/ImageMagick/issues) and [closed](https://github.com/ImageMagick/ImageMagick/issues?q=is%3Aissue+is%3Aclosed) issues to ensure it has not already been reported
### Description
<!-- A description of the bug or feature -->
Potential memory leak in function WritePDFImage in coders/pdf.c, which is similar to but different from #576.
### Steps to Reproduce
<!-- List of steps, sample code, failing test or link to a project that reproduces the behavior.
Make sure you place a stack trace inside a code (```) block to avoid linking unrelated issues -->
**xref** is allocated at line [L1362](https://github.com/ImageMagick/ImageMagick/blob/master/coders/pdf.c#L1362) or reallocated at line [L1499](https://github.com/ImageMagick/ImageMagick/blob/master/coders/pdf.c#L1499).
```c
1362: xref=(MagickOffsetType *) AcquireQuantumMemory(2048UL,sizeof(*xref));
1499: xref=(MagickOffsetType *) ResizeQuantumMemory(xref,(size_t) count+2048UL,
sizeof(*xref));
```
However, when the function returns with *MagickFalse* (such as [L1902](https://github.com/ImageMagick/ImageMagick/blob/master/coders/pdf.c#L1902) and [L1912](https://github.com/ImageMagick/ImageMagick/blob/master/coders/pdf.c#L1912)), **xref** was neither passed outside to the caller function nor freed. I believe the two positions needs to free **xref** because **xref** is freed at the **default case** at [L1931](https://github.com/ImageMagick/ImageMagick/blob/master/coders/pdf.c#L1931) while the 2 positions locates in another 2 cases of a switch statement. So memory leak can happen at line **1902** and **1912**.
There are many similar positions including [L1965](https://github.com/ImageMagick/ImageMagick/blob/master/coders/pdf.c#L1965), [L2011](https://github.com/ImageMagick/ImageMagick/blob/master/coders/pdf.c#L2011), [L2021](https://github.com/ImageMagick/ImageMagick/blob/master/coders/pdf.c#L2021), [L2082](https://github.com/ImageMagick/ImageMagick/blob/master/coders/pdf.c#L2082), [L2179](https://github.com/ImageMagick/ImageMagick/blob/master/coders/pdf.c#L2179), [L2427](https://github.com/ImageMagick/ImageMagick/blob/master/coders/pdf.c#L1362), [L2437](https://github.com/ImageMagick/ImageMagick/blob/master/coders/pdf.c#L2437), [L2488](https://github.com/ImageMagick/ImageMagick/blob/master/coders/pdf.c#L2488), [L2529](https://github.com/ImageMagick/ImageMagick/blob/master/coders/pdf.c#L2529), [L2539](https://github.com/ImageMagick/ImageMagick/blob/master/coders/pdf.c#L2539), [L2594](https://github.com/ImageMagick/ImageMagick/blob/master/coders/pdf.c#L2594), [L2682](https://github.com/ImageMagick/ImageMagick/blob/master/coders/pdf.c#L2682) and [L2894](https://github.com/ImageMagick/ImageMagick/blob/master/coders/pdf.c#L2894).

### Description
<!-- A description of the bug or feature -->
memory leak in WriteDIBImage in coders/dib.c
### Steps to Reproduce
<!-- List of steps, sample code, failing test or link to a project that reproduces the behavior.
Make sure you place a stack trace inside a code (```) block to avoid linking unrelated issues -->
The critical code snippets are:
https://github.com/ImageMagick/ImageMagick/blob/master/coders/dib.c#L1330
```c
if (dib_info.bits_per_pixel == 8) //line 1330
if (image_info->compression != NoCompression) //line 1331
{
size_t
length;
/*
Convert run-length encoded raster pixels.
*/
length=2UL*(bytes_per_line+2UL)+2UL;
dib_data=(unsigned char *) AcquireQuantumMemory(length, // line 1340
(image->rows+2UL)*sizeof(*dib_data));
if (dib_data == (unsigned char *) NULL)
{
pixels=(unsigned char *) RelinquishMagickMemory(pixels);
ThrowWriterException(ResourceLimitError,"MemoryAllocationFailed");
}
dib_info.image_size=(unsigned int) EncodeImage(image,bytes_per_line,
pixels,dib_data);
pixels=(unsigned char *) RelinquishMagickMemory(pixels);
pixels=dib_data; // line 1350
dib_info.compression = BI_RLE8;
}
```
and
https://github.com/ImageMagick/ImageMagick/blob/master/coders/dib.c#L1367
```c
if (image->storage_class == PseudoClass) //line 1367
{
if (dib_info.bits_per_pixel <= 8) //line 1369
{
unsigned char
*dib_colormap;
/*
Dump colormap to file.
*/
dib_colormap=(unsigned char *) AcquireQuantumMemory((size_t)
(1UL << dib_info.bits_per_pixel),4*sizeof(*dib_colormap));
if (dib_colormap == (unsigned char *) NULL) // line 1379
ThrowWriterException(ResourceLimitError,"MemoryAllocationFailed"); // line 1380
q=dib_colormap;
```
According to the code in function WriteDIBImage before line 1330, when **image->storage_class** is not **DirectClass** (i.e. storage class is **PseudoClass**) and **image_info->depth<=8**, **dib_info.bits_per_pixel** can be equal to **8** (at line 1151-1155), as a result, **dib_info.compression** will be BI_RGB (at line 1164-1165). **So the 4 conditions at line 1330, 1331, 1367 and 1369 can be satisfied at the same time in some setting.**
When the 4 conditions are satisfied and **dib_data** is successfully allocated at line **1340**, **dib_data** will be assigned to **pixels** at line **1350**. However, when the allocation at line **1377** fails, the function don't free **dib_data** memory as done at line **1410** before returning with exception at line **1378**. As a result, a memory leak will happen.
The size of leaked memory is 4*((image->columns*dib_info.bits_per_pixel+31)/32)*(image->rows+2UL)*sizeof(*dib_data) = (image->columns + 4) * (image->rows + 2) * sizeof(*dib_data), which may be a large value. (ps. dib_info.bits_per_pixel is 8)
Patch Suggestion:
```c
dib_colormap=(unsigned char *) AcquireQuantumMemory((size_t) // line 1377
(1UL << dib_info.bits_per_pixel),4*sizeof(*dib_colormap));
if (dib_colormap == (unsigned char *) NULL)
{
pixels=(unsigned char *) RelinquishMagickMemory(pixels);
ThrowWriterException(ResourceLimitError,"MemoryAllocationFailed");
}
q=dib_colormap;
```

A Heap-buffer-overflow problem was discovered in function AP4_BitStream::WriteBytes(unsigned char const*, unsigned int) in Ap4BitStream.cpp. A crafted input can cause segment faults and I have confirmed them with address sanitizer too.
Here are the POC files. Please use "./avcinfo $POC" to reproduce the error.
