Ubuntu Security Notice 6782-1 - Multiple security issues were discovered in Thunderbird. If a user were tricked into opening a specially crafted website in a browsing context, an attacker could potentially exploit these to cause a denial of service, obtain sensitive information, bypass security restrictions, cross-site tracing, or execute arbitrary code. Thomas Rinsma discovered that Thunderbird did not properly handle type check when handling fonts in PDF.js. An attacker could potentially exploit this issue to execute arbitrary javascript code in PDF.js.

Ubuntu Security Notice 6777-3 - Zheng Wang discovered that the Broadcom FullMAC WLAN driver in the Linux kernel contained a race condition during device removal, leading to a use- after-free vulnerability. A physically proximate attacker could possibly use this to cause a denial of service. Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system.

### Summary On Windows, fetching refs that clash with legacy device names reads from the devices, and checking out paths that clash with such names writes arbitrary data to the devices. This allows a repository, when cloned, to cause indefinite blocking or the production of arbitrary message that appear to have come from the application, and potentially other harmful effects under limited circumstances. ### Details It is possible to create a Git repository that contains references or filenames that Windows treats as legacy DOS-style aliases for system devices. When such a repository is cloned: - In references, `gix-ref` does not include a check for such names before attempting to access them on disk, which reads from the devices, though the ability to exfiltrate data appears limited. - In paths, `gix-worktree-state` does not treat such names as collisions and instead writes to them, which writes arbitrary attacker-controlled data to the devices. Some such device names refer to dev...

Ubuntu Security Notice 6780-1 - Guido Vranken discovered that idna did not properly manage certain inputs, which could lead to significant resource consumption. An attacker could possibly use this issue to cause a denial of service.
