Synopsis
========
libxslt is affected by a heap-based buffer overflow, possibly leading
to the execution of arbitrary code.
Background
==========
libxslt is the XSLT C library developed for the GNOME project. XSLT is
an XML language to define transformations for XML.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 dev-libs/libxslt lt; 1.1.24-r1 gt;= 1.1.24-r1
lt; 1.1.8
Description
===========
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.
Resolution
==========
All libxslt users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose "gt;=dev-libs/libxslt-1.1.24-r1"
References
==========
