How to fix?

Upgrade Oracle:8 libxml2 to version 0:2.9.7-18.el8_9 or higher.
This issue was patched in ELSA-2024-0119.

NVD Description

Note: Versions mentioned in the description apply only to the upstream libxml2 package and not the libxml2 package as distributed by Oracle. See How to fix? for Oracle:8 relevant fixed versions and status.

Xmlsoft Libxml2 v2.11.0 was discovered to contain an out-of-bounds read via the xmlSAX2StartElement() function at /libxml2/SAX2.c. This vulnerability allows attackers to cause a Denial of Service (DoS) via supplying a crafted XML file. NOTE: the vendor's position is that the product does not support the legacy SAX1 interface with custom callbacks; there is a crash even without crafted input.
