CVE-2015-7941 Detail

Description

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.


Evaluator Description

"context dependent" seems to point to MiTM attack due to: If a user or automated system were tricked into opening a specially crafted document, an attacker could possibly cause libxml2 to crash, resulting in a denial of service. This issue only affected Ubuntu 12.04 LTS, Ubuntu 14.04 LTS and Ubuntu 15.04.
