GLSA-200808-06 : libxslt: Execution of arbitrary code

high Nessus Plugin ID 33836

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.

Solution

All libxslt users should upgrade to the latest version:
 # emerge --sync # emerge --ask --oneshot --verbose '>=dev-libs/libxslt-1.1.24-r1'
