ID: 200411-02

Synopsis

Cherokee contains a format string vulnerability that could lead to denial of service or the execution of arbitary code.

Background

Description

Florian Schilhabel from the Gentoo Linux Security Audit Team found a format string vulnerability in the cherokee_logger_ncsa_write_string() function.

Impact

Using a specially crafted URL when authenticating via auth_pam, a malicious user may be able to crash the server or execute arbitrary code on the target machine with permissions of the user running Cherokee.

Workaround

There is no known workaround at this time.
