CVE-2013-4520 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2013-4520): xslt.c in libxslt before 1.1.25 allows context-dependent attackers to cause a denial of service (crash) via a stylesheet that embeds a DTD, which causes a structure to be accessed as a different type. NOTE: this issue is due to an incomplete fix for CVE-2012-2825. Just filing to make CVETool happy, nothing to see here.
