Severity: Normal
Title: GnuPG: User-assisted execution of arbitrary code
Date: October 22, 2011
Bugs: #329583
ID: 201110-15
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Synopsis
========
The GPGSM utility included in GnuPG contains a use-after-free
vulnerability that may allow an unauthenticated remote attacker to
execute arbitrary code.
Background
==========
The GNU Privacy Guard, GnuPG, is a free replacement for the PGP suite
of cryptographic software. The GPGSM utility in GnuPG is responsible
for processing X.509 certificates, signatures and encryption as well as
S/MIME messages.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 app-crypt/gnupg < 2.0.16-r1 >= 2.0.16-r1
< 2.0
Description
===========
The GPGSM utility in GnuPG contains a use-after-free vulnerability that
may be exploited when importing a crafted X.509 certificate explicitly
or during the signature verification process.
Impact
======
An unauthenticated remote attacker may execute arbitrary code with the
privileges of the user running GnuPG by enticing them to import a
crafted certificate.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All GnuPG 2.x users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-crypt/gnupg-2.0.16-r1"
References
==========
[ 1 ] CVE-2010-2547
