Synopsis
========
Multiple vulnerabilities have been found in GnuTLS, the worst of which
may allow execution of arbitrary code.
Background
==========
GnuTLS is an Open Source implementation of the TLS and SSL protocols.
Affected packages
=================
——————————————————————-
Package / Vulnerable / Unaffected
——————————————————————-
1 net-libs/gnutls < 3.3.26 >= 3.3.26
Description
===========
Multiple heap and stack overflows and double free vulnerabilities have
been discovered in GnuTLS by the OSS-Fuzz project. Please review the
CVE identifiers referenced below for details.
Impact
======
A remote attacker could entice a user or automated system to process a
specially crafted certificate using an application linked against
GnuTLS. This could possibly result in the execution of arbitrary code
with the privileges of the process or a Denial of Service condition.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All GnuTLS users should upgrade to the latest version:
# emerge –sync
# emerge –ask –oneshot –verbose “>=net-libs/gnutls-3.3.26”
