Description: Debian has reported a vulnerability, which can be exploited by malicious, local users to overwrite certain files on the system. The vulnerability has been identified in "ps2epsi", which creates a temporary file in an insecure manner when calling ghostscript. The problem is that there are no checks to determine, whether the file already exists or is linked to another place. Successful exploitation allows a malicious user to overwrite files on the system owned by the user invoking "ps2epsi" by conducting a symlink attack. Solution: Updated packages: -- Debian GNU/Linux 3.0 alias woody -- Source archives: http://security.debian.org/pool/updat...gs-common/gs-common_0.3.3.0woody1.dsc Size/MD5 checksum: 522 16e9ffda57fcdb6c48e977e499fd8671 http://security.debian.org/pool/updat...common/gs-common_0.3.3.0woody1.tar.gz Size/MD5 checksum: 16202 9588ecfa64ccffdc50df77cdf282edc0 Architecture independent components: http://security.debian.org/pool/updat...ommon/gs-common_0.3.3.0woody1_all.deb Size/MD5 checksum: 23008 77cc8798e636d26f6fa3a9913afc1de4 -- Debian GNU/Linux unstable alias sid -- Fixed in version 0.3.3.1.
