Synopsis :

The remote Gentoo host is missing one or more security-related
patches.

Description :

The remote host is affected by the vulnerability described in GLSA-200603-02
(teTeX, pTeX, CSTeX: Multiple overflows in included XPdf code)

CSTeX, teTex, and pTeX include XPdf code to handle PDF files. This
XPdf code is vulnerable to several heap overflows (GLSA 200512-08) as
well as several buffer and integer overflows discovered by Chris Evans
(CESA-2005-003).

Impact :

An attacker could entice a user to open a specially crafted PDF
file with teTeX, pTeX or CSTeX, potentially resulting in the execution
of arbitrary code with the rights of the user running the affected
application.

Workaround :

There is no known workaround at this time.
