Bugs:	#402861
ID:	201203-08

Synopsis

A vulnerability in libxslt could result in Denial of Service.

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	Architecture(s)
dev-libs/libxslt	< 1.1.26-r3	>= 1.1.26-r3	All supported architectures

Description

An out of bounds read error has been found in libxslt/pattern.c in libxslt.

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 resulting in a Denial of Service condition.

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 ">=dev-libs/libxslt-1.1.26-r3"
