EPSS 2.46%
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.
