3. Description:

frysk is an execution-analysis technology implemented using native Java and
C++. It provides developers and system administrators with the ability to
examine and analyze multi-host, multi-process, and multithreaded systems
while they are running. frysk is released as a Technology Preview for Red
Hat Enterprise Linux 4.

A buffer overflow flaw was found in HarfBuzz, an OpenType text shaping
engine used in the embedded Pango library. If a frysk application were used
to debug or trace a process that uses HarfBuzz while it loaded a
specially-crafted font file, it could cause the application to crash or,
possibly, execute arbitrary code with the privileges of the user running
the application. (CVE-2011-3193)

Users of frysk are advised to upgrade to this updated package, which
contains a backported patch to correct this issue. All running frysk
applications must be restarted for this update to take effect.

4. Solution:

Before applying this update, make sure all previously-released errata
relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to
use the Red Hat Network to apply this update are available at
