Mark Richters discovered a buffer overflow in the open_sty() function
|
||
|
|
in file mkind.c. Other vulnerabilities have also been discovered in the
|
||
|
|
same file but might not be exploitable (CVE-2007-0650). Tetex also
|
||
|
|
includes vulnerable code from GD library (GLSA 200708-05), and from
|
||
|
|
Xpdf (CVE-2007-3387).

A remote attacker could entice a user to process a specially crafted
|
||
|
|
PNG, GIF or PDF file, or to execute "makeindex" on an overly long
|
||
|
|
filename. In both cases, this could lead to the remote execution of
|
||
|
|
arbitrary code with the privileges of the user running the application.

<workaround>
|
||
|
|
<p>
|
||
|
|
There is no known workaround at this time.

All teTeX users should upgrade to the latest version:
