Description Riccardo Schirone 2020-04-29 14:06:17 UTC 
An issue was discovered in libgit2 where checkout.c mishandles equivalent filenames that exist because of NTFS short names. This may allow remote code execution when cloning a repository. This issue is the libgit2 variant of CVE-2019-1353.

Comment 5 Riccardo Schirone 2020-04-30 08:00:59 UTC 
Statement:

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 nor Windows Subsystem for Linux (WSL). For this reason, the flaw has a Low Impact.
