GLSA-200406-16 : Apache 1.3: Buffer overflow in mod_proxy

critical Nessus Plugin ID 14527

Synopsis

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

Description

The remote host is affected by the vulnerability described in GLSA-200406-16 (Apache 1.3: Buffer overflow in mod_proxy)

 A bug in the proxy_util.c file may lead to a remote buffer overflow. To trigger the vulnerability an attacker would have to get mod_proxy to connect to a malicous server which returns an invalid (negative) Content-Length.
 Impact :

 An attacker could cause a Denial of Service as the Apache child handling the request, which will die and under some circumstances execute arbitrary code as the user running Apache, usually 'apache'.
 Workaround :

 There is no known workaround at this time. All users are encouraged to upgrade to the latest available version:

Solution

Apache 1.x users should upgrade to the latest version of Apache:
 # emerge sync # emerge -pv '>=www-servers/apache-1.3.31-r2' # emerge '>=www-servers/apache-1.3.31-r2'
