"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).

description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
