CPE [?]: cpe:/o:gentoo:linux, p-cpe:/a:gentoo:linux:mod_jk

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-200703-16 (Apache JK Tomcat Connector: Remote execution of arbitrary code)

ZDI reported an unsafe memory copy in mod_jk that was discovered by an anonymous researcher in the map_uri_to_worker function of native/common/jk_uri_worker_map.c . Impact :

A remote attacker can send a long URL request to an Apache server using Tomcat. That can trigger the vulnerability and lead to a stack-based buffer overflow, which could result in the execution of arbitrary code with the permissions of the Apache user. Workaround :

There is no known workaround at this time.

Solution

All Apache Tomcat users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose '>=www-apache/mod_jk-1.2.21-r1'
