announced via advisory USN-633-1.
A security issue affects the following Ubuntu releases:
Ubuntu 6.06 LTS
Ubuntu 7.04
Ubuntu 7.10

This advisory also applies to the corresponding versions of
Kubuntu, Edubuntu, and Xubuntu.
Details follow:
It was discovered that long transformation matches in libxslt could
overflow. If an attacker were able to make an application linked against
libxslt process malicious XSL style sheet input, they could execute
arbitrary code with user privileges or cause the application to crash,
leading to a denial of serivce. (CVE-2008-1767)
Chris Evans discovered that the RC4 processing code in libxslt did not
correctly handle corrupted key information. If a remote attacker were
able to make an application linked against libxslt process malicious
XML input, they could crash the application, leading to a denial of
service. (CVE-2008-2935)
Solution:
The problem can be corrected by upgrading your system to the
following package versions:
Ubuntu 6.06 LTS:
libxslt1.1 1.1.15-1ubuntu1.2

In general, a standard system upgrade is sufficient to effect the
necessary changes.
