Update now! Two critical flaws in Git's code found, patched

CVE-2022-23521 and CVE-2022-41903 are critical flaws present in Git's code. Thankfully, they’ve been addressed in its latest version. (Read more...) The post Update now! Two critical flaws in Git's code found, patched appeared first on Malwarebytes Labs.

Git Users Urged to Update Software to Prevent Remote Code Execution Attacks

The maintainers of the Git source code version control system have released updates to remediate two critical vulnerabilities that could be exploited by a malicious actor to achieve remote code execution. The flaws, tracked as CVE-2022-23521 and CVE-2022-41903, impacts the following versions of Git: v2.30.6, v2.31.5, v2.32.4, v2.33.5, v2.34.5, v2.35.5, v2.36.3, v2.37.4, v2.38.2, and v2.39.0.

CVE-2022-41903: Heap overflow in `git archive`, `git log --format` leading to RCE

Git is distributed revision control system. `git log` can display commits in an arbitrary format using its `--format` specifiers. This functionality is also exposed to `git archive` via the `export-subst` gitattribute. When processing the padding operators, there is a integer overflow in `pretty.c::format_and_pad_commit()` where a `size_t` is stored improperly as an `int`, and then added as an offset to a `memcpy()`. This overflow can be triggered directly by a user running a command which invokes the commit formatting machinery (e.g., `git log --format=...`). It may also be triggered indirectly through git archive via the export-subst mechanism, which expands format specifiers inside of files within the repository during a git archive. This integer overflow can result in arbitrary heap writes, which may result in arbitrary code execution. The problem has been patched in the versions published on 2023-01-17, going back to v2.30.7. Users are advised to upgrade. Users who are unable to u...

CVE-2022-23521: gitattributes parsing integer overflow

Git is distributed revision control system. gitattributes are a mechanism to allow defining attributes for paths. These attributes can be defined by adding a `.gitattributes` file to the repository, which contains a set of file patterns and the attributes that should be set for paths matching this pattern. When parsing gitattributes, multiple integer overflows can occur when there is a huge number of path patterns, a huge number of attributes for a single pattern, or when the declared attribute names are huge. These overflows can be triggered via a crafted `.gitattributes` file that may be part of the commit history. Git silently splits lines longer than 2KB when parsing gitattributes from a file, but not when parsing them from the index. Consequentially, the failure mode depends on whether the file exists in the working tree, the index or both. This integer overflow can result in arbitrary heap reads and writes, which may result in remote code execution. The problem has been patched i...
