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 < 1.1.24-r1 >= 1.1.24-r1 < 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 ">=dev-libs/libxslt-1.1.24-r1" References ========== [ 1 ] CVE-2008-2935 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-2935 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200808-06.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.
