DESCRIPTION
gv is a program which uses the Ghostscript PostScript interpreter to
display PostScript and PDF documents under the X Window System.
kghostview is a KDE application which does the same.
Zen Parse found[1] a buffer overflow vulnerability in gv version
3.5.8 and earlier. kghostview (from kdegraphics versions prior to
3.0.4) is also affected, since it has some code derived from the same
project. An attacker can exploit this vulnerability by creating a
carefully crafted pdf file that, when opened by gv or kghostview,
causes the execution of arbitrary code.
The Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the name CAN-2002-0838 to this issue[2].
SOLUTION
All gv and kdegraphics users are advised to upgrade.
ADDITIONAL INSTRUCTIONS
Users of Conectiva Linux version 6.0 or higher may use apt to perform
upgrades of RPM packages:
- add the following line to /etc/apt/sources.list if it is not there yet
(you may also use linuxconf to do this):
(replace 6.0 with the correct version number if you are not running CL6.0)
- run: apt-get update
- after that, execute: apt-get upgrade
