Ubuntu: PCRE vulnerability Print E-mail
User Rating:      How can I rate this item?
Posted by Benjamin D. Thomas   
Ubuntu It was discovered that PCRE did not correctly handle very long strings containing UTF8 sequences. In certain situations, an attacker could exploit applications linked against PCRE by tricking a user or automated system in processing a malicious regular expression leading to a denial of service or possibly arbitrary code execution.
=========================================================== 
Ubuntu Security Notice USN-581-1          February 21, 2008
pcre3 vulnerability
CVE-2008-0674
===========================================================

A security issue affects the following Ubuntu releases:

Ubuntu 6.06 LTS
Ubuntu 6.10
Ubuntu 7.04
Ubuntu 7.10

This advisory also applies to the corresponding versions of
Kubuntu, Edubuntu, and Xubuntu.

The problem can be corrected by upgrading your system to the
following package versions:

Ubuntu 6.06 LTS:
  libpcre3                        7.4-0ubuntu0.6.06.2

Ubuntu 6.10:
  libpcre3                        7.4-0ubuntu0.6.10.2

Ubuntu 7.04:
  libpcre3                        7.4-0ubuntu0.7.04.2

Ubuntu 7.10:
  libpcre3                        7.4-0ubuntu0.7.10.2

After a standard system upgrade you need to reboot your computer to
effect the necessary changes.

Details follow:

It was discovered that PCRE did not correctly handle very long strings
containing UTF8 sequences.  In certain situations, an attacker could
exploit applications linked against PCRE by tricking a user or automated
system in processing a malicious regular expression leading to a denial
of service or possibly arbitrary code execution.
