Date:	05/05/2005
Bugs:	#91303
ID:	200505-02

Synopsis

The Oops! proxy server contains a remotely exploitable format string vulnerability, which could potentially lead to the execution of arbitrary code.

Background

Oops! is an advanced, multithreaded caching web proxy.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
net-proxy/oops	< 1.5.24_pre20050503	>= 1.5.24_pre20050503	All supported architectures

Description

A format string flaw has been detected in the my_xlog() function of the Oops! proxy, which is called by the passwd_mysql and passwd_pgsql module's auth() functions.

Impact

A remote attacker could send a specially crafted HTTP request to the Oops! proxy, potentially triggering this vulnerability and leading to the execution of arbitrary code.

Workaround

There is no known workaround at this time.

Resolution
