GLSA-200612-10 : Tar: Directory traversal vulnerability

medium Nessus Plugin ID 23862

Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

The remote host is affected by the vulnerability described in GLSA-200612-10 (Tar: Directory traversal vulnerability)

 Tar does not properly extract archive elements using the GNUTYPE_NAMES record name, allowing files to be created at arbitrary locations using symlinks. Once a symlink is extracted, files after the symlink in the archive will be extracted to the destination of the symlink.
 Impact :

 An attacker could entice a user to extract a specially crafted tar archive, possibly allowing for the overwriting of arbitrary files on the system extracting the archive.
 Workaround :

 There is no known workaround at this time.

Solution

All Tar users should upgrade to the latest version:
 # emerge --sync # emerge --ask --oneshot --verbose '>=app-arch/tar-1.16-r2'
