An issue was discovered in libgit2 where path.c mishandles equivalent filenames that exist because of NTFS Alternate Data Streams. This may allow remote code execution when cloning a repository. This issue is the libgit2 variant of CVE-2019-1352.
Even if the code in the versions of libgit2 as shipped with Red Hat Enterprise Linux 7, and 8 are affected by this flaw, Red Hat does not support the NTFS filesystem. For this reason, the flaw has a Low Impact.
