Synopsis :

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

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.
