CVE-2007-4770, CVE-2007-4771
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=

=3D=3D=3D=3D=3D=3D=3D=3D=3D

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:
libicu34 3.4.1a-1ubuntu1.6.06.1

Ubuntu 6.10:
libicu34 3.4.1a-1ubuntu1.6.10.1

Ubuntu 7.04:
libicu36 3.6-2ubuntu0.1

Ubuntu 7.10:
libicu36 3.6-3ubuntu0.1

After a standard system upgrade you need to restart applications linked
against libicu, such as OpenOffice.org, to effect the necessary changes.

Details follow:

Will Drewry discovered that libicu did not properly handle '\\0' when
processing regular expressions. If an application linked against libicu
processed a crafted regular expression, an attacker could execute
arbitrary code with privileges of the user invoking the program.
(CVE-2007-4770)

Will Drewry discovered that libicu did not properly limit its
backtracking stack size. If an application linked against libicu
processed a crafted regular expression, an attacker could cause a denial
of service via resource exhaustion. (CVE-2007-4771)
