CVE-2018-12015
In Perl through 5.26.2, the Archive::Tar module allows remote attackers to bypass a directory-traversal protection mechanism, and overwrite arbitrary files, via an archive file containing a symlink and a regular file with the same name.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (7.31%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
