TITLE

Google Chrome Used in libxslt Service disruption in (DoS) Vulnerabilities

DESCRIPTION

libxslt 1.1.26 and earlier, as used in Google Chrome before 21.0.1180.89, does not properly manage memory, which might allow remote attackers to cause a denial of service (application crash) via a crafted XSLT expression that is not properly identified during XPath navigation, related to (1) the xsltCompileLocationPathPattern function in libxslt/pattern.c and (2) the xsltGenerateIdFunction function in libxslt/functions.c. (1) libxslt/pattern.c of xsltCompileLocationPathPattern function (2) libxslt/functions.c of xsltGenerateIdFunction function. Google Chrome is prone to multiple security vulnerabilities. Attackers can exploit these issues to execute arbitrary code in the context of the browser, cause denial-of-service conditions, execute arbitrary script code in the browser of an unsuspecting user or steal cookie-based authentication credentials; other attacks are also possible. Versions prior to Chrome 21.0.1180.89 are vulnerable. A vulnerability exists in libxslt 1.1.26 and earlier versions using Google Chrome prior to 21.0.1180.89 due to improper memory management. An attacker with a privileged network position may inject arbitrary contents. This issue was addressed by using an encrypted HTTPS connection to retrieve tutorials. Summary: Updated libxslt packages that fix several security issues are now available for Red Hat Enterprise Linux 5 and 6. The Red Hat Security Response Team has rated this update as having important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. 2.

Description: libxslt is a library for transforming XML files into other textual formats (including HTML, plain text, and other XML representations of the underlying data) using the standard XSLT stylesheet transformation mechanism. A heap-based buffer overflow flaw was found in the way libxslt applied templates to nodes selected by certain namespaces. An attacker could use this flaw to create a malicious XSL file that, when used by an application linked against libxslt to perform an XSL transformation, could cause the application to crash or, possibly, execute arbitrary code with the privileges of the user running the application. (CVE-2012-2871) Several denial of service flaws were found in libxslt. An attacker could use these flaws to create a malicious XSL file that, when used by an application linked against libxslt to perform an XSL transformation, could cause the application to crash. (CVE-2012-2825, CVE-2012-2870, CVE-2011-3970) An information leak could occur if an application using libxslt processed an untrusted XPath expression, or used a malicious XSL file to perform an XSL transformation. If combined with other flaws, this leak could possibly help an attacker bypass intended memory corruption protections. (CVE-2011-1202) All libxslt users are advised to upgrade to these updated packages, which contain backported patches to resolve these issues. All running applications linked against libxslt must be restarted for this update to take effect. 4. This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/knowledge/articles/11258 5.

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 < 1.1.28 >= 1.1.28 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). 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-1.1.28" Packages which depend on this library may need to be recompiled. Tools such as revdep-rebuild may assist in identifying some of these packages.
