Package : tetex-bin Vulnerability : arbitrary command execution Problem-type : remote Debian-specific: no CVE Id : CAN-2002-0836
The SuSE security team discovered a vulnerability in kpathsea library (libkpathsea) which is used by xdvi and dvips. Both programs call the system() function insecurely, which allows a remote attacker to execute arbitrary commands via cleverly crafted DVI files.
If dvips is used in a print filter, this allows a local or remote attacker with print permission execute arbitrary code as the printer user (usually lp).
This problem has been fixed in version 1.0.7+20011202-7.1for the current stable distribution (woody), in version 1.0.6-7.3 for the old stable distribution (potato) and in version 1.0.7+20021025-4 for the unstable distribution (sid). xdvik-ja and dvipsk-ja are vulnerable as well, but link to the kpathsea library dynamically and will automatically be fixed after a new libkpathsea is installed.
We recommend that you upgrade your tetex-lib package immediately.
wget url will fetch the file for you dpkg -i file.deb will install the referenced file.
If you are using the apt-get package manager, use the line for sources.list as given below:
apt-get update will update the internal database apt-get upgrade will install corrected packages
