Buffer overflows in dvips and dviljk could be triggered by specially crafted dvi files (CVE-2007-5935, CVE-2007-5937). dvips additionally created temporary files in an insecure manner (CVE-2007-5936).

The remote host is affected by the vulnerability described in GLSA-200711-26 (teTeX: Multiple vulnerabilities)

    Joachim Schrod discovered several buffer overflow vulnerabilities and     an insecure temporary file creation in the 'dvilj' application that is     used by dvips to convert DVI files to printer formats (CVE-2007-5937,     CVE-2007-5936). Bastien Roucaries reported that the 'dvips' application     is vulnerable to two stack-based buffer overflows when processing DVI     documents with long \\href{} URIs (CVE-2007-5935). teTeX also includes     code from Xpdf that is vulnerable to a memory corruption and two     heap-based buffer overflows (GLSA 200711-22); and it contains code from     T1Lib that is vulnerable to a buffer overflow when processing an overly     long font filename (GLSA 200710-12).
  Impact :

    A remote attacker could entice a user to process a specially crafted     DVI or PDF file which could lead to the execution of arbitrary code     with the privileges of the user running the application. A local     attacker could exploit the 'dvilj' vulnerability to conduct a symlink     attack to overwrite arbitrary files.
  Workaround :

    There is no known workaround at this time.

A flaw in the t1lib library where an attacker could create a malicious file that would cause tetex to crash or possibly execute arbitrary code when opened (CVE-2007-4033).

Alin Rad Pop found several flaws in how PDF files are handled in tetex. An attacker could create a malicious PDF file that would cause tetex to crash or potentially execute arbitrary code when opened (CVE-2007-4352, CVE-2007-5392, CVE-2007-5393).

A stack-based buffer overflow in dvips in tetex allows for user-assisted attackers to execute arbitrary code via a DVI file with a long href tag (CVE-2007-5935).

A vulnerability in dvips in tetex allows local users to obtain sensitive information and modify certain data by creating certain temporary files before they are processed by dviljk, which can then be read or modified in place (CVE-2007-5936).

Multiple buffer overflows in dviljk in tetext may allow users-assisted attackers to execute arbitrary code via a crafted DVI input file (CVE-2007-5937).

The updated packages have been patched to correct this issue.

Bastien Roucaries discovered that dvips as included in tetex-bin and texlive-bin did not properly perform bounds checking. If a user or automated system were tricked into processing a specially crafted dvi file, dvips could be made to crash and execute code as the user invoking the program. (CVE-2007-5935)

Joachim Schrod discovered that the dviljk utilities created temporary files in an insecure way. Local users could exploit a race condition to create or overwrite files with the privileges of the user invoking the program. (CVE-2007-5936)

Joachim Schrod discovered that the dviljk utilities did not perform bounds checking in many instances. If a user or automated system were tricked into processing a specially crafted dvi file, the dviljk utilities could be made to crash and execute code as the user invoking the program. (CVE-2007-5937).
