CVE-2015-7941: Canonical Ubuntu Linux

Medium severity, CVSS 4.3. EPSS: 3.1% chance of exploitation in the next 30 days.

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.

Affected products

• Canonical Ubuntu Linux: version 12.04 only; version 14.04 only; version 15.04 only
• Xmlsoft LIBXML2: version 2.9.2 only
