CVE-2020-22907

2021-07-13T15:15:08.677

Stack overflow vulnerability in function jsi_evalcode_sub in jsish before 3.0.18, allows remote attackers to cause a Denial of Service via a crafted value to the execute parameter.

CVE-2020-19717

2021-07-13T22:15:08.943

An unhandled memory allocation failure in Core/Ap48bdlAtom.cpp of Bento 1.5.1-628 causes a NULL pointer dereference, leading to a denial of service (DOS).

There is a null pointer dereference caused by unhandled exhaustive memory usage in Ap48bdlAtom.cpp. Distributor ID: Ubuntu Description: Ubuntu 16.04.6 LTS Release: 16.04 Codename: xenial gcc: 5.4.0 To reproduce the bug, compile the project with flag DCMAKE_C_FLAGS=-g -m32 -fsanitize=address,undefined then run: ./mp42aac input /dev/null The reason is that the malloc size does not check and easily lead to memory allocation failure.

There is a buffer overflow inside AP4_IkmsAtom of AP4IkmsAtom.cpp. It is similar to #412 and #396. ./mp42aac input_file /dev/null In file Source/C++/Core/AP4IkmsAtom.cpp AP4_RtpAtom allocates a new buffer to parse the atom in the stream. The unhandled memory allocation failure causes the read content memcpy to a null pointer. This is the start points.  In file In file Source/C++/Core/AP4IkmsAtom.cpp   AP4_CopyMemory is the macro define of memcpy and the path formed.

CVE-2020-23330

2021-08-17T22:15:07.823

An issue was discovered in Bento4 version 06c39d9. A NULL pointer dereference exists in the AP4_Stz2Atom::GetSampleSize component located in /Core/Ap4Stz2Atom.cpp. It allows an attacker to cause a denial of service (DOS).

detected a heap error or that the target was executing a heap function when it stopped. This could be due to heap corruption, passing a bad pointer to a heap function such as free(), etc. Since heap errors might include buffer overflows, use-after-free situations, etc. they are generally considered exploitable. ---END SUMMARY---

CVE-2020-23333

2021-08-17T22:15:07.940

A heap-based buffer overflow exists in the AP4_CttsAtom::AP4_CttsAtom component located in /Core/Ap4Utils.h of Bento4 version 06c39d9. This can lead to a denial of service (DOS).

CVE-2021-25735

2021-09-06T12:15:07.617

A security issue was discovered in kube-apiserver that could allow node updates to bypass a Validating Admission Webhook. Clusters are only affected by this vulnerability if they run a Validating Admission Webhook for Nodes that denies admission based at least partially on the old state of the Node object. Validating Admission Webhook does not observe some previous fields.

A security issue was discovered in kube-apiserver that could allow node updates to bypass a Validating Admission Webhook. You are only affected by this vulnerability if you run a Validating Admission Webhook for Nodes that denies admission based at least partially on the old state of the Node object. This issue has been rated **Medium** ([CVSS:3.0/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:H/A:H](https://www.first.org/cvss/calculator/3.0#CVSS:3.0/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:H/A:H)), and assigned **CVE-2021-25735**. **Note:** This only impacts validating admission plugins that rely on old values in certain fields, and does not impact calls from kubelets that go through the built-in NodeRestriction admission plugin. #### Affected Versions - kube-apiserver v1.20.0 - v1.20.5 - kube-apiserver v1.19.0 - v1.19.9 - kube-apiserver <= v1.18.17 #### Fixed Versions This issue is fixed in the following versions: - kube-apiserver v1.21.0 - Fixed by https://github.com/kubernetes/kubernetes/pull/99946 - kube-apiserver v1.20.6 - Fixed by https://github.com/kubernetes/kubernetes/pull/100315 - kube-apiserver v1.19.10 - Fixed by https://github.com/kubernetes/kubernetes/pull/100316 - kube-apiserver v1.18.18 - Fixed by https://github.com/kubernetes/kubernetes/pull/100317 #### Detection If you find evidence that this vulnerability has been exploited, please contact [email protected] #### Acknowledgements This vulnerability was reported by Rogerio Bastos & Ari Lima from RedHat

CVE-2021-25737

2021-09-06T12:15:07.673

A security issue was discovered in Kubernetes where a user may be able to redirect pod traffic to private networks on a Node. Kubernetes already prevents creation of Endpoint IPs in the localhost or link-local range, but the same validation was not performed on EndpointSlice IPs.

#### Issue Details A security issue was discovered in Kubernetes where a user may be able to redirect pod traffic to private networks on a Node. Kubernetes already prevents creation of Endpoint IPs in the localhost or link-local range, but the same validation was not performed on EndpointSlice IPs. This issue has been rated Low ([CVSS:3.0/AV:N/AC:L/PR:H/UI:N/S:U/C:L/I:N/A:N](https://www.first.org/cvss/calculator/3.0#CVSS:3.0/AV:N/AC:L/PR:H/UI:N/S:U/C:L/I:N/A:N)), and assigned CVE-2021-25737. Affected Component kube-apiserver #### Affected Versions v1.21.0 v1.20.0 - v1.20.6 v1.19.0 - v1.19.10 v1.16.0 - v1.18.18 (Note: EndpointSlices were not enabled by default in 1.16-1.18) #### Fixed Versions This issue is fixed in the following versions: v1.21.1 v1.20.7 v1.19.11 v1.18.19 #### Mitigation To mitigate this vulnerability without upgrading kube-apiserver, you can create a validating admission webhook that prevents EndpointSlices with endpoint addresses in the 127.0.0.0/8 and 169.254.0.0/16 ranges. If you have an existing admission policy mechanism (like OPA Gatekeeper) you can create a policy that enforces this restriction. #### Detection To detect whether this vulnerability has been exploited, you can list EndpointSlices and check for endpoint addresses in the 127.0.0.0/8 and 169.254.0.0/16 ranges. If you find evidence that this vulnerability has been exploited, please contact [email protected] #### Acknowledgements This vulnerability was reported by John Howard of Google.

CVE-2021-32265

2021-09-20T16:15:09.913

An issue was discovered in Bento4 through v1.6.0-637. A global-buffer-overflow exists in the function AP4_MemoryByteStream::WritePartial() located in Ap4ByteStream.cpp. It allows an attacker to cause code execution or information disclosure.
