Amazon Linux AMI : rsyslog (ALAS-2012-105)

low Nessus Plugin ID 69595

Synopsis

The remote Amazon Linux AMI host is missing a security update.

Description

A numeric truncation error, leading to a heap-based buffer overflow, was found in the way the rsyslog imfile module processed text files containing long lines. An attacker could use this flaw to crash the rsyslogd daemon or, possibly, execute arbitrary code with the privileges of rsyslogd, if they are able to cause a long line to be written to a log file that rsyslogd monitors with imfile. The imfile module is not enabled by default. (CVE-2011-4623)

Solution

Run 'yum update rsyslog' to update your system.
