Background ========== Libxslt is the XSLT C library developed for the GNOME project. XSLT itself is an XML language to define transformations for XML. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 dev-libs/libxslt < 1.1.24 >= 1.1.24 Description =========== Anthony de Almeida Lopes reported a vulnerability in libxslt when handling XSL style-sheet files, which could be exploited to trigger the use of uninitialized memory, e.g. in a call to "free()". Impact ====== A remote attacker could entice a user or automated system to process an XML file using a specially crafted XSL transformation file, possibly resulting in the execution of arbitrary code or a Denial of Service. 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-1.1.24" References ========== [ 1 ] CVE-2008-1767 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-1767 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200806-02.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
