Severity:	normal
Title:	Logsurfer: Arbitrary code execution
Date:	01/20/2012
Bugs:	#387397
ID:	201201-04

Synopsis

A double-free flaw in Logsurfer allows a remote attacker to execute arbitrary code.

Background

Logsurfer is a real time log monitoring and analysis tool.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
app-admin/logsurfer+	< 1.8	>= 1.8	All supported architectures

Description

Logsurfer log files may contain substrings used for executing external commands. The prepare_exec() function in src/exec.c contains a double-free vulnerability.

Impact

A remote attacker could inject specially-crafted strings into a log file processed by Logsurfer, resulting in the execution of arbitrary code with the permissions of the Logsurfer user.

Workaround

There is no known workaround at this time.

Resolution

All Logsurfer users should upgrade to the latest version:

      # emerge --sync
      # emerge --ask --oneshot --verbose ">=app-admin/logsurfer+-1.8"
