Summary
git security update
Details

Git is a free and open source distributed version control system designed to handle everything from small to very large projects with speed and efficiency. Git is easy to learn and has a tiny footprint with lightning fast performance. It outclasses SCM tools like Subversion, CVS, Perforce, and ClearCase with features like cheap local branching, convenient staging areas, and multiple workflows.

Security Fix(es):

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 in the versions published on 2023-01-17, going back to v2.30.7. Users are advised to upgrade. There are no known workarounds for this issue.(CVE-2022-23521)

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 upgrade should disable git archive in untrusted repositories. If you expose git archive via git daemon, disable it by running git config --global daemon.uploadArch false.(CVE-2022-41903)
