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-200801-01
(unp: Arbitrary command execution)

Erich Schubert from Debian discovered that unp does not escape file
names properly before passing them to calls of the shell.

Impact :

A remote attacker could entice a user or automated system to unpack a
compressed archive with a specially crafted file name, leading to the
execution of shell commands from within the filename. That code will be
executed with the privileges of the user running unp.

Workaround :

There is no known workaround at this time.

Solution :

All unp users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=app-arch/unp-1.0.14'

Risk factor :

Critical / CVSS Base Score : 10.0
