Ubuntu: PCRE vulnerabilities Print E-mail
User Rating:      How can I rate this item?
Posted by Benjamin D. Thomas   
Ubuntu Tavis Ormandy and Will Drewry discovered multiple flaws in the regular expression handling of PCRE. By tricking a user or service into running specially crafted expressions via applications linked against libpcre3, a remote attacker could crash the application, monopolize CPU resources, or possibly execute arbitrary code with the application's privileges.
=========================================================== 
Ubuntu Security Notice USN-547-1          November 27, 2007
pcre3 vulnerabilities
CVE-2007-1659, CVE-2007-1660, CVE-2007-1661, CVE-2007-1662,
CVE-2007-4766, CVE-2007-4767, CVE-2007-4768
===========================================================

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                        7.4-0ubuntu0.6.06.1
  libpcrecpp0                     7.4-0ubuntu0.6.06.1

Ubuntu 6.10:
  libpcre3                        7.4-0ubuntu0.6.10.1
  libpcrecpp0                     7.4-0ubuntu0.6.10.1

Ubuntu 7.04:
  libpcre3                        7.4-0ubuntu0.7.04.1
  libpcrecpp0                     7.4-0ubuntu0.7.04.1

Ubuntu 7.10:
  libpcre3                        7.4-0ubuntu0.7.10.1
  libpcrecpp0                     7.4-0ubuntu0.7.10.1

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

Due to the large internal code changes needed to solve outstanding flaws,
it was not possible to backport all the upstream security fixes to the
earlier released versions.  To address this, the pcre3 library has been
updated to the latest stable release (7.4), which includes fixes for
all known security issues.  While the new version is ABI compatible,
efforts have been taken to maintain behavioral compatibility with the
earlier versions.

Details follow:

Tavis Ormandy and Will Drewry discovered multiple flaws in the regular
expression handling of PCRE.  By tricking a user or service into running
specially crafted expressions via applications linked against libpcre3,
a remote attacker could crash the application, monopolize CPU resources,
or possibly execute arbitrary code with the application's privileges.
