GLSA 200504-29: Pound: Buffer overflow vulnerability

http://security.gentoo.org/

Severity:	high
Title:	Pound: Buffer overflow vulnerability
Date:	04/30/2005
Bugs:	#90851
ID:	200504-29

Synopsis

Pound is vulnerable to a buffer overflow that could lead to the remote execution of arbitrary code.

Background

Pound is a reverse proxy, load balancer and HTTPS front-end.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
www-servers/pound	< 1.8.3	>= 1.8.3	All supported architectures

Description

Steven Van Acker has discovered a buffer overflow vulnerability in the "add_port()" function in Pound.

Impact

A remote attacker could send a request for an overly long hostname parameter, which could lead to the remote execution of arbitrary code with the rights of the Pound daemon process (by default, Gentoo uses the "nobody" user to run the Pound daemon).

Workaround

There is no known workaround at this time.

Resolution

All Pound users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=www-servers/pound-1.8.3"
