CVE-2015-7942

Publication date 23 October 2015

Last updated 24 July 2024

Ubuntu priority

Medium

Why this priority?

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.
