Details

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)
