Ubuntu Security Notice 6509-1 - Multiple security issues were discovered in Firefox. If a user were tricked into opening a specially crafted website, an attacker could potentially exploit these to cause a denial of service, obtain sensitive information across domains, or execute arbitrary code. It was discovered that Firefox did not properly manage memory when images were created on the canvas element. An attacker could potentially exploit this issue to obtain sensitive information.

CSZ CMS version 1.3.0 suffers from a remote shell upload vulnerability.

Vim is a UNIX editor that, prior to version 9.0.2121, has a heap-use-after-free vulnerability. When executing a `:s` command for the very first time and using a sub-replace-special atom inside the substitution part, it is possible that the recursive `:s` call causes free-ing of memory which may later then be accessed by the initial `:s` command. The user must intentionally execute the payload and the whole process is a bit tricky to do since it seems to work only reliably for the very first :s command. It may also cause a crash of Vim. Version 9.0.2121 contains a fix for this issue.

Buffer Overflow vulnerability in zlib-ng minizip-ng v.4.0.2 allows an attacker to execute arbitrary code via a crafted file to the mz_path_resolve function in the mz_os.c file.

Ubuntu Security Notice 6506-1 - David Shoon discovered that the Apache HTTP Server mod_macro module incorrectly handled certain memory operations. A remote attacker could possibly use this issue to cause the server to crash, resulting in a denial of service. Prof. Sven Dietrich, Isa Jafarov, Prof. Heejo Lee, and Choongin Lee discovered that the Apache HTTP Server incorrectly handled certain HTTP/2 connections. A remote attacker could possibly use this issue to cause the server to consume resources, leading to a denial of service. This issue only affected Ubuntu 23.04, and Ubuntu 23.10.

Ubuntu Security Notice 6505-1 - It was discovered that nghttp2 incorrectly handled request cancellation. A remote attacker could possibly use this issue to cause nghttp2 to consume resources, leading to a denial of service.

Ubuntu Security Notice 6503-1 - Yu Hao discovered that the UBI driver in the Linux kernel did not properly check for MTD with zero erasesize during device attachment. A local privileged attacker could use this to cause a denial of service. Bien Pham discovered that the netfiler subsystem in the Linux kernel contained a race condition, leading to a use-after-free vulnerability. A local user could use this to cause a denial of service or possibly execute arbitrary code.

Ubuntu Security Notice 6502-1 - Ivan D Barrera, Christopher Bednarz, Mustafa Ismail, and Shiraz Saleem discovered that the InfiniBand RDMA driver in the Linux kernel did not properly check for zero-length STAG or MR registration. A remote attacker could possibly use this to execute arbitrary code. Yu Hao discovered that the UBI driver in the Linux kernel did not properly check for MTD with zero erasesize during device attachment. A local privileged attacker could use this to cause a denial of service.

Ubuntu Security Notice 6501-1 - It was discovered that RabbitMQ incorrectly handled certain HTTP requests. An attacker could possibly use this issue to cause a denial of service.
