Gentoo Linux Security Advisory GLSA 200504-29
http://security.gentoo.org/
Severity: High
Title: Pound: Buffer overflow vulnerability
Date: April 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
-------------------------------------------------------------------
1 www-servers/pound < 1.8.3 >= 1.8.3
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"
