Name of the Vulnerable Software and Affected Versions libgit2 versions prior to 0.28.4 libgit2 versions 0.9x prior to 0.99.0

Description The issue is related to the path.c component of libgit2, which mishandles equivalent filenames due to NTFS Alternate Data Streams. This may allow a remote attacker to access confidential data, compromise its integrity, and cause a denial of service. The issue can also potentially allow remote code execution when cloning a repository.

Recommendations For libgit2 versions prior to 0.28.4, update to version 0.28.4 or later. For libgit2 versions 0.9x prior to 0.99.0, update to version 0.99.0 or later.
