Synopsis

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

Affected packages

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