Name of the Vulnerable Software and Affected Versions libgit2 versions prior to 0.24.3

Description The issue allows remote attackers to cause a denial of service, specifically a NULL pointer dereference, by utilizing a cat-file command with a crafted object file. This is related to the git oid nfmt function in commit.c.

Recommendations For versions prior to 0.24.3, update to version 0.24.3 or later to resolve the issue. As a temporary workaround, consider restricting access to crafted object files to minimize the risk of exploitation.
