Detailsinfo

A vulnerability was found in Apple macOS up to 10.14.3 (Operating System) and classified as critical. Affected by this issue is an unknown code block of the component Perl. The manipulation with an unknown input leads to a path traversal vulnerability. Using CWE to declare the problem leads to CWE-22.

Impacted is integrity, and availability. CVE summarizes:

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.
