Ubuntu Security Notice 5673-1 - It was discovered that unzip did not properly handle unicode strings under certain circumstances. If a user were tricked into opening a specially crafted zip file, an attacker could possibly use this issue to cause unzip to crash, resulting in a denial of service, or possibly execute arbitrary code. It was discovered that unzip did not properly perform bounds checking while converting wide strings to local strings. If a user were tricked into opening a specially crafted zip file, an attacker could possibly use this issue to cause unzip to crash, resulting in a denial of service, or possibly execute arbitrary code.

Ubuntu Security Notice 5672-1 - It was discovered that GMP did not properly manage memory on 32-bit platforms when processing a specially crafted input. An attacker could possibly use this issue to cause applications using GMP to crash, resulting in a denial of service.

Ubuntu Security Notice 5671-1 - It was discovered that AdvanceCOMP did not properly manage memory of function be_uint32_read under certain circumstances. If a user were tricked into opening a specially crafted binary file, a remote attacker could possibly use this issue to cause AdvanceCOMP to crash, resulting in a denial of service. It was discovered that AdvanceCOMP did not properly manage memory of function adv_png_unfilter_8 under certain circumstances. If a user were tricked into opening a specially crafted PNG file, a remote attacker could possibly use this issue to cause AdvanceCOMP to crash, resulting in a denial of service.

Ubuntu Security Notice 5670-1 - Edward Thomson discovered that .NET 6 incorrectly handled permissions for local NuGet cache. A local attacker could possibly use this issue to execute arbitrary code.

Microsoft's Patch Tuesday update for the month of October has addressed a total of 85 security vulnerabilities, including fixes for an actively exploited zero-day flaw in the wild. Of the 85 bugs, 15 are rated Critical, 69 are rated Important, and one is rated Moderate in severity. The update, however, does not include mitigations for the actively exploited ProxyNotShell flaws in Exchange Server

Ubuntu Security Notice 5669-1 - It was discovered that the SUNRPC RDMA protocol implementation in the Linux kernel did not properly calculate the header size of a RPC message payload. A local attacker could use this to expose sensitive information. Moshe Kol, Amit Klein and Yossi Gilad discovered that the IP implementation in the Linux kernel did not provide sufficient randomization when calculating port offsets. An attacker could possibly use this to expose sensitive information.

Ubuntu Security Notice 5667-1 - Selim Enes Karaduman discovered that a race condition existed in the General notification queue implementation of the Linux kernel, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. Pawan Kumar Gupta, Alyssa Milburn, Amit Peled, Shani Rehana, Nir Shildan and Ariel Sabba discovered that some Intel processors with Enhanced Indirect Branch Restricted Speculation did not properly handle RET instructions after a VM exits. A local attacker could potentially use this to expose sensitive information.

Ubuntu Security Notice 5668-1 - It was discovered that the BPF verifier in the Linux kernel did not properly handle internal data structures. A local attacker could use this to expose sensitive information. It was discovered that an out-of-bounds write vulnerability existed in the Video for Linux 2 implementation in the Linux kernel. A local attacker could use this to cause a denial of service or possibly execute arbitrary code.

Ubuntu Security Notice 5669-2 - It was discovered that the SUNRPC RDMA protocol implementation in the Linux kernel did not properly calculate the header size of a RPC message payload. A local attacker could use this to expose sensitive information. Moshe Kol, Amit Klein and Yossi Gilad discovered that the IP implementation in the Linux kernel did not provide sufficient randomization when calculating port offsets. An attacker could possibly use this to expose sensitive information.

Ubuntu Security Notice 5657-1 - It was discovered that Graphite2 mishandled specially crafted files. An attacker could possibly use this issue to cause a denial of service or other unspecified impact.
