Date:	08/11/2024
Bugs:	#842846
ID:	202408-28

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	Architecture(s)
app-admin/rsyslog	< 8.2206.0	>= 8.2206.0	All supported architectures

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"
