A flaw was found in Git, a distributed revision control system. When parsing gitattributes, a mechanism to allow defining attributes for paths, multiple integer overflows can occur when there is a huge number of path patterns, attributes for a single pattern, or declared attribute names. 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 allow remote code execution.

Created git tracking bugs for this issue: Affects: fedora-36 [bug 2162065] Affects: fedora-37 [bug 2162066] Hello there, If it's not the correct location for this comment, please redirect me to a better place ;-) Do you have any ETA about the availability of the fix in the affected lines of your Docker images? UBI 7-9 are affected since more than 2 weeks, usually you are providing the corrections in a very reactive (and appreciated) way, making this one a bit weird (along with CVE-2022-41903). Also I saw that the score was moving from Critical to High and now back to Critical. In the meantime, do you have a workaround recommendation?
