Last modified

CVE-2015-7942 is a vulnerability of currently unknown severity. The xmlParseConditionalSections function in parser.c in libxml2 does not properly skip intermediary entities when it stops parsing invalid input, which allows context-dependent attackers to cause a denial of service (out-of-bounds read and crash) via crafted XML data, a different vulnerability than CVE-2015-7941.. EPSS estimates a 4.74% chance of exploitation in the next 30 days.
