Ubuntu Security Notice 6013-1 - Xuewei Feng, Chuanpu Fu, Qi Li, Kun Sun, and Ke Xu discovered that the TCP implementation in the Linux kernel did not properly handle IPID assignment. A remote attacker could use this to cause a denial of service or inject forged data. Ke Sun, Alyssa Milburn, Henrique Kawakami, Emma Benoit, Igor Chervatyuk, Lisa Aichele, and Thais Moreira Hamasaki discovered that the Spectre Variant 2 mitigations for AMD processors on Linux were insufficient in some situations. A local attacker could possibly use this to expose sensitive information.

This Metasploit module exploits an authentication bypass vulnerability in the Linux version of udadmin_server, which is an RPC service that comes with the Rocket Software UniData server. This affects versions of UniData prior to 8.2.4 build 3003. This service typically runs as root. It accepts a username of ":local:" and a password in the form of "::", where username and uid must be a valid account, but gid can be anything except 0. This exploit takes advantage of this login account to authenticate as a chosen user and run an arbitrary command (using the built-in OsCommand message).

This Metasploit module exploits an authentication bypass vulnerability in the Linux version of udadmin_server, which is an RPC service that comes with the Rocket Software UniData server, which runs as root. This vulnerability affects UniData versions 8.2.4 build 3003 and earlier (for Linux), but this module specifically targets UniData version 8.2.4 build 3001. Other versions will crash the forked process, but will not otherwise affect the RPC server. The username and password fields are copied to a stack-based buffer using a function that's equivalent to strcpy() (ie, has no bounds checking). Additionally, the password field is encoded in such a way that we can include NUL bytes.

Red Hat Security Advisory 2023-1743-01 - Node.js is a software development platform for building fast and scalable network applications in the JavaScript programming language. Issues addressed include buffer overflow, bypass, and denial of service vulnerabilities.

Ubuntu Security Notice 6009-1 - It was discovered that the System V IPC implementation in the Linux kernel did not properly handle large shared memory counts. A local attacker could use this to cause a denial of service. It was discovered that a use-after-free vulnerability existed in the SGI GRU driver in the Linux kernel. A local attacker could possibly use this to cause a denial of service or possibly execute arbitrary code.
