============================================================================

A security issue affects these releases of Ubuntu and its derivatives:

KOffice could be made to crash or run programs as your login if it opened
a specially crafted file.

Software Description:
- koffice: KDE Office Suite

Details:

It was discovered that KOffice incorrectly handled certain malformed
MS Word documents. If a user or automated system were tricked into opening
a crafted MS Word file, an attacker could cause a denial of service or
execute arbitrary code with privileges of the user invoking the program.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 11.10:
  koffice                         1:2.3.3-0ubuntu6.1

necessary changes.
