CVE-2012-2870

libxslt v1.1.26 y anteriores, tal como se utiliza en Google Chrome anterior a v21.0.1180.89, no gestiona adecuadamente la memoria, lo que podría permitir a atacantes remotos provocar una denegación de servicio (caída de aplicación) a través de una elaborada expresión XSLT que no esté debidamente identificado durante XPath navegación, en relación con (1) la función xsltCompileLocationPathPattern en libxslt / pattern.c y (2) la función xsltGenerateIdFunction en libxslt / functions.c.

Unspecified vulnerability in XSLT allows remote attackers to obtain potentially sensitive information about heap memory addresses via unknown vectors. libxslt 1.1.26 and earlier does not properly manage memory, which might allow remote attackers to cause a denial of service via a crafted XSLT expression that is not properly identified during XPath navigation, related to the xsltCompileLocationPathPattern function in libxslt/pattern.c and the xsltGenerateIdFunction function in libxslt/functions.c. libxml2 2.9.0-rc1 and earlier does not properly support a cast of an unspecified variable during handling of XSL transforms, which allows remote attackers to cause a denial of service or possibly have unknown other impact via a crafted document, related to the _xmlNs data structure in include/libxml/tree.h. Double free vulnerability in libxslt allows remote attackers to cause a denial of service or possibly have unspecified other impact via vectors related to XSL transforms. The updated packages have been patched to correct these issues.
