Gentoo Linux Security Advisory

Title: libxslt: Denial of Service (GLSA 201401-07)
Severity: normal
Exploitable: remote
Date: January 10, 2014
Bug(s): #433603, #436284, #463236, #496114
ID: 201401-07

Synopsis

Multiple Denial of Service vulnerabilities have been found in
libxslt.


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: dev-libs/libxslt
Vulnerable: < 1.1.28
Unaffected: >= 1.1.28
Architectures: All supported architectures


Description

Multiple vulnerabilities have been found in libxslt:
  • Multiple errors exist in pattern.c and functions.c (CVE-2012-2870,
    CVE-2012-6139).
  • A double-free error exists in templates.c (CVE-2012-2893).
  • A NULL pointer dereference in keys.c (CVE-2012-6139).
  • An error in handling stylesheets containing DTDs (CVE-2013-4520).


Impact

A remote attacker could entice a user to process a specially crafted
file 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:
Code:
# emerge --sync
      # emerge --ask --oneshot --verbose ">=dev-libs/libxslt-1.1.28"
   
Packages which depend on this library may need to be recompiled. Tools
such as revdep-rebuild may assist in identifying some of these packages.
