===========================================================
Ubuntu Security Notice USN-994-1         September 29, 2010
libhx vulnerability
CVE-2010-2947
===========================================================

A security issue affects the following Ubuntu releases:

Ubuntu 8.04 LTS
Ubuntu 9.04
Ubuntu 9.10
Ubuntu 10.04 LTS

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 8.04 LTS:
  libhx10                         1.10.2-2ubuntu0.1

Ubuntu 9.04:
  libhx14                         1.28-1ubuntu0.1

Ubuntu 9.10:
  libhx18                         2.9-3ubuntu0.1

Ubuntu 10.04 LTS:
  libhx22                         3.2-1ubuntu0.1

In general, a standard system update will make all the necessary changes.

Details follow:

It was discovered that libHX incorrectly handled certain parameters to the
HX_split function. An attacker could use this flaw to cause a denial of
service or possibly execute arbitrary code with the privileges of the user.

The default compiler options for affected releases should reduce the
vulnerability to a denial of service.
