GLSA-200612-03 : GnuPG: Multiple vulnerabilities

This script is Copyright (C) 2006-2015 Tenable Network Security, Inc.

Synopsis :

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

Description :

The remote host is affected by the vulnerability described in GLSA-200612-03
(GnuPG: Multiple vulnerabilities)

Hugh Warrington has reported a boundary error in GnuPG, in the
'ask_outfile_name()' function from openfile.c: the
make_printable_string() function could return a string longer than
expected. Additionally, Tavis Ormandy of the Gentoo Security Team
reported a design error in which a function pointer can be incorrectly

Impact :

A remote attacker could entice a user to interactively use GnuPG on a
crafted file and trigger the boundary error, which will result in a
buffer overflow. They could also entice a user to process a signed or
encrypted file with gpg or gpgv, possibly called through another
application like a mail client, to trigger the dereference error. Both
of these vulnerabilities would result in the execution of arbitrary
code with the permissions of the user running GnuPG. gpg-agent, gpgsm
and other tools are not affected.

Workaround :

There is no known workaround at this time.

Solution :

All GnuPG users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '=app-crypt/gnupg-1.4*'

Risk factor :

Critical / CVSS Base Score : 10.0
CVSS Temporal Score : 8.7
Public Exploit Available : false
