Vulnerability Details : CVE-2013-4520
Potential exploit
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.
