Oops!: Remote code execution

Background

Oops! is an advanced, multithreaded caching web proxy.

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

All Oops! users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=net-proxy/oops-1.5.24_pre20050503"
