CVE-2015-7941 is a vulnerability of currently unknown severity. libxml2 2.9.2 does not properly stop parsing invalid input, which allows context-dependent attackers to cause a denial of service (out-of-bounds read and libxml2 crash) via crafted XML data to the (1) xmlParseEntityDecl or (2) xmlParseConditionalSections function in parser.c, as demonstrated by non-terminated entities.. EPSS estimates a 3.07% chance of exploitation in the next 30 days.
