CVE-2015-5312

Publication date 26 November 2015

Last updated 24 July 2024

The xmlStringLenDecodeEntities function in parser.c in libxml2 before 2.9.3 does not properly prevent entity expansion, which allows context-dependent attackers to cause a denial of service (CPU consumption) via crafted XML data, a different vulnerability than CVE-2014-3660.
