GLSA 200803-21: Sarg: Remote execution of arbitrary code

http://security.gentoo.org/

Severity:	normal
Title:	Sarg: Remote execution of arbitrary code
Date:	03/12/2008
Bugs:	#212208, #212731
ID:	200803-21

Synopsis

Sarg is vulnerable to the execution of arbitrary code when processed with untrusted input files.

Background

Sarg (Squid Analysis Report Generator) is a tool that provides many informations about the Squid web proxy server users activities: time, sites, traffic, etc.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
net-analyzer/sarg	< 2.2.5	>= 2.2.5	All supported architectures

Description

Sarg doesn't properly check its input for abnormal content when processing Squid log files.

Impact

A remote attacker using a vulnerable Squid as a proxy server or a reverse-proxy server can inject arbitrary content into the "User-Agent" HTTP client header, that will be processed by sarg, which will lead to the execution of arbitrary code, or JavaScript injection, allowing Cross-Site Scripting attacks and the theft of credentials.

Workaround

There is no known workaround at this time.

Resolution

All sarg users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=net-analyzer/sarg-2.2.5"
