GLSA-200407-18 : mod_ssl: Format string vulnerability

Medium Nessus Plugin ID 14551


The remote Gentoo host is missing one or more security-related patches.


The remote host is affected by the vulnerability described in GLSA-200407-18 (mod_ssl: Format string vulnerability)

A bug in ssl_engine_ext.c makes mod_ssl vulnerable to a ssl_log() related format string vulnerability in the mod_proxy hook functions.
Impact :

Given the right server configuration, an attacker could execute code as the user running Apache, usually 'apache'.
Workaround :

A server should not be vulnerable if it is not using both mod_ssl and mod_proxy. Otherwise there is no workaround other than to disable mod_ssl.


All mod_ssl users should upgrade to the latest version:
# emerge sync # emerge -pv '>=net-www/mod_ssl-2.8.19' # emerge '>=net-www/mod_ssl-2.8.19'
