CVE-2015-7941  (opens in a new tab)
CWE-119  (opens in a new tab)

How to fix?

Upgrade Debian:9 libxml2 to version 2.9.2+really2.9.1+dfsg1-0.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream libxml2 package and not the libxml2 package as distributed by Debian. See How to fix? for Debian:9 relevant fixed versions and status.

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.
