Synopsis
========
A vulnerability has been discovered in rsyslog, which could possibly
lead to remote code execution.
Background
==========
rsyslog is an enhanced multi-threaded syslogd with database support and
more.
Affected packages
=================
Package Vulnerable Unaffected
----------------- ------------ ------------
app-admin/rsyslog < 8.2206.0 >= 8.2206.0
Description
===========
Multiple vulnerabilities have been discovered in rsyslog. Please review
the CVE identifiers referenced below for details.
Impact
======
Modules for TCP syslog reception have a heap buffer overflow when octet-
counted framing is used. The attacker can corrupt heap values, leading
to data integrity issues and availability impact. Remote code execution
is unlikely to happen but not impossible.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All rsyslog users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-admin/rsyslog-8.2206.0"
