USN-236-2: xpdf vulnerabilities in kword, kpdf

9 January 2006

kdegraphics, koffice vulnerabilities

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

  • Ubuntu 5.10
  • Ubuntu 5.04

Software Description

Details

USN-236-1 fixed several vulnerabilities in xpdf. kpdf and kword contain copies of xpdf code and are thus vulnerable to the same issues.

For reference, this is the original advisory:

Chris Evans discovered several integer overflows in the XPDF code, which is present in xpdf, the Poppler library, and tetex-bin. By tricking an user into opening a specially crafted PDF file, an attacker could exploit this to execute arbitrary code with the privileges of the application that processes the document.

Update instructions

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

Ubuntu 5.10
kpdf
kword
Ubuntu 5.04
kpdf
kword

To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
