Description msiddiqu 2020-12-23 13:03:17 UTC
Archive_Tar through 1.4.10 has :// filename sanitization only to address phar attacks, and thus any other stream-wrapper attack (such as file:// to overwrite files) can still succeed.

Comment 3 Doran Moppert 2020-12-24 01:21:52 UTC
Note this vulnerability affects the php Archive_Tar package, not the perl package with the same name.  Archive_Tar is included in Fedora and Red Hat Enterprise Linux bundled in the php-pear package.
