USN-173-2: PCRE vulnerability
Posted on: 08/24/2005 05:00 PM

A new PCRE vulnerability update is available for Ubuntu Linux. Here the announcement:

Ubuntu Security Notice USN-173-2 August 24, 2005
pcre3, apache2 vulnerabilities
CAN-2005-2491
==========================
==========================
=========

A security issue affects the following Ubuntu releases:

Ubuntu 4.10 (Warty Warthog)
Ubuntu 5.04 (Hoary Hedgehog):

The following packages are affected:

apache2
apache2-mpm-perchild
apache2-mpm-prefork
apache2-mpm-threadpool
apache2-mpm-worker
libpcre3

The problem can be corrected by upgrading the affected package to
version 2.0.50-12ubuntu4.4 (apache2 for Ubuntu 4.10),
4.5-1.1ubuntu0.4.10.1 (libpcre3 for Ubuntu4.10), or
4.5-1.1ubuntu0.5.04.1 (libpcre3 for Ubuntu 5.04).

A standard system upgrade is NOT SUFFICIENT to effect the necessary
changes! If you can afford to reboot your machine, this is the easiest
way to ensure that all services using this library are restarted
correctly. If not, please manually restart all server processes (exim,
PHP, etc.). It is advised to also restart your desktop session.


Details follow:

USN-173-1 fixed a buffer overflow vulnerability in the PCRE library.
However, it was determined that this did not suffice to prevent all
possible overflows, so another update is necessary.

In addition, it was found that the Ubuntu 4.10 version of Apache 2
contains a static copy of the library code, so this package needs to
be updated as well. In Ubuntu 5.04, Apache 2 uses the external library
from the libpcre3 package.


Updated packages for Ubuntu 4.10 (Warty Warthog):
