NVD Description

Note: Versions mentioned in the description apply only to the upstream libxml2-python package and not the libxml2-python package as distributed by RHEL. See How to fix? for RHEL:7 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.
