| Description: | Description:
The remote host is missing an update to xpdf/cupsys/tetex-bin/kdegraphics/koffice
announced via advisory USN-227-1.
A security issue affects the following Ubuntu releases:
Ubuntu 4.10 (Warty Warthog)
Ubuntu 5.04 (Hoary Hedgehog)
Ubuntu 5.10 (Breezy Badger)
The following packages are affected:
cupsys
cupsys-bsd
cupsys-client
kpdf
kword
libpoppler0c2
tetex-bin
xpdf-reader
xpdf-utils
infamous41md discovered several integer overflows in the XPDF code,
which is present in xpdf, the Poppler library, tetex-bin, KOffice, and
kpdf. 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.
The CUPS printing system also uses XPDF code to convert PDF files to
PostScript. By attempting to print such a crafted PDF file, a remote
attacker could execute arbitrary code with the privileges of the
printer server (user 'cupsys').
Solution:
The problem can be corrected by upgrading the affected package to the
following versions:
Ubuntu 4.10:
xpdf: 3.00-8ubuntu1.9
cupsys: 1.1.20final+cvs20040330-4ubuntu16.9
tetex-bin: 2.0.2-21ubuntu0.7
Ubuntu 5.04:
xpdf: 3.00-11ubuntu3.5
tetex-bin: 2.0.2-25ubuntu0.3
kword: 1:1.3.5-2ubuntu1.2
kpdf: 4:3.4.0-0ubuntu3.2
Ubuntu 5.10:
libpoppler0c2: 0.4.2-0ubuntu6.4
tetex-bin: 2.0.2-30ubuntu3.3
kword: 1:1.4.1-0ubuntu7.1
kpdf: 4:3.4.3-0ubuntu2.1
In general, a standard system upgrade is sufficient to effect the
necessary changes.
