MGASA-2012-0272 Date: September 15th, 2012 Affected releases: 2 Description: Updated libxslt packages fix security vulnerabilities: libxslt 1.1.26 and earlier 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 (CVE-2012-2870). 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). Updated Packages: lib(64)xslt1-1.1.26-6.20120127.3.mga2 lib(46)xslt-devel-1.1.26-6.20120127.3.mga2 python-libxslt-1.1.26-6.20120127.3.mga2 xsltproc-1.1.26-6.20120127.3.mga2 References: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2012-2870 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2012-2871 https://rhn.redhat.com/errata/RHSA-2012-1265.html https://bugs.mageia.org/show_bug.cgi?id=7480 https://wiki.mageia.org/en/Support/Advisories/MGASA-2012-...
