Description Riccardo Schirone 2018-06-29 15:04:50 UTC

A flaw was found in libgit2 which allows arbitrary file write when recursively cloning a malicious repository. libgit2 can be tricked into writing files outside the .git/modules directory. This is a variant of git CVE-2018-11235.

Comment 1 Riccardo Schirone 2018-06-29 15:05:25 UTC

Created libgit2 tracking bugs for this issue:

Affects: fedora-all [bug 1596744]

Comment 2 Riccardo Schirone 2018-07-03 12:09:20 UTC

After deeper analysis with upstream help, we determined libgit2 is not vulnerable to any variant of CVE-2018-11235.
Thus I'm closing this as NOTABUG.
