ID:	202305-09

Synopsis

A denial of service vulnerability was discovered in rsyslog related to syslog input over the network.

Background

syslog replacement with advanced filtering features.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
app-admin/syslog-ng	< 3.38.1	>= 3.38.1	All supported architectures

Description

An integer overflow in the RFC3164 parser allows remote attackers to cause a denial of service via crafted syslog input that is mishandled by the tcp or network function.

Impact

Attackers with access to input syslogs over syslog-ng's network functionality can cause a denial of service.

Workaround

There is no known workaround at this time.

Resolution

All syslog-ng users should upgrade to the latest version:

          # emerge --ask --oneshot --verbose ">=app-admin/syslog-ng-3.38.1"
