GLSA-200801-01 : unp: Arbitrary command execution

critical Nessus Plugin ID 29905

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'
