The [libgit2](https://github.com/libgit2/libgit2/) project fixed three security issues in the 1.7.2 release. These issues are: * The `git_revparse_single` function can potentially enter an infinite loop on a well-crafted input, potentially causing a Denial of Service. This function is exposed in the `git2` crate via the [`Repository::revparse_single`](https://docs.rs/git2/latest/git2/struct.Repository.html#method.revparse_single) method. * The `git_index_add` function may cause heap corruption and possibly lead to arbitrary code execution. This function is exposed in the `git2` crate via the [`Index::add`](https://docs.rs/git2/latest/git2/struct.Index.html#method.add) method. * The smart transport negotiation may experience an out-of-bounds read when a remote server did not advertise capabilities. The `libgit2-sys` crate bundles libgit2, or optionally links to a system libgit2 library. In either case, versions of the libgit2 library less than 1.7.2 are vulnerable. The 0.16.2 release ...

Debian Linux Security Advisory 5619-1 - Two vulnerabilities were discovered in libgit2, a low-level Git library, which may result in denial of service or potentially the execution of arbitrary code.

### Summary When processing requests authorization was improperly and insufficiently checked, allowing attackers to access far more functionality than users intended, including to the administrative and moderator functionality of the Pixelfed server. This vulnerability affects every version of Pixelfed between `v0.10.4` and `v0.11.9`, inclusive. A proof of concept of this vulnerability exists. ### Details TBA. This advisory will be edited with more details on 2024/02/25, when admins have been given some time to update, as we think any amount of detail would make it very easy to come up with an exploit. ### Impact This vulnerability affects every local user of a Pixelfed server, and can potentially affect the servers' ability to federate. Some user interaction is required to setup the conditions to be able to exercise the vulnerability, but the attacker could conduct this attack time-delayed manner, where user interaction is not actively required.

Ubuntu Security Notice 6631-1 - Several security issues were discovered in the WebKitGTK Web and JavaScript engines. If a user were tricked into viewing a malicious website, a remote attacker could exploit a variety of issues related to web browser security, including cross-site scripting attacks, denial of service attacks, and arbitrary code execution.

Ubuntu Security Notice 6630-1 - It was discovered that Glance_store incorrectly handled logging when the DEBUG log level is enabled. A local attacker could use this issue to obtain access_key values.

This is additional research regarding a mitigation bypass in Windows Defender. Back in 2022, the researcher disclosed how it could be easily bypassed by passing an extra path traversal when referencing mshtml but that issue has since been mitigated. However, the researcher discovered using multiple commas can also be used to achieve the bypass.

An issue was discovered on WyreStorm Apollo VX20 versions prior to 1.3.58. Remote attackers can restart the device via a /device/reboot HTTP GET request.
