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

2.  Impact Information


Oops! is an advanced, multithreaded caching web proxy.


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.


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.

3.  Resolution Information


There is no known workaround at this time.


All Oops! users should upgrade to the latest version:
