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-200808-06
(libxslt: Execution of arbitrary code)

Chris Evans (Google Security) reported that the libexslt library that
is part of libxslt is affected by a heap-based buffer overflow in the
RC4 encryption/decryption functions.

Impact :

A remote attacker could entice a user to process an XML file using a
specially crafted XSLT stylesheet in an application linked against
libxslt, possibly leading to the execution of arbitrary code with the
privileges of the user running the application.

Workaround :

There is no known workaround at this time.
