Red Hat Security Advisory: Red Hat Hardened Images RPMs bug fix and enhancement update

xmlregexp in libxml2 before 2.15.4 has a NULL pointer dereference in xmlRegNewParserCtxt after a strdup failure, i.e., it does not calculate a string length after NULL checking.

The vulnerability in libxml2 (xmlregexp) prior to version 2.15.4 is due to an unchecked return value from strdup, which can return NULL. The function xmlRegNewParserCtxt does not handle this NULL pointer correctly and proceeds without recalculating string length, causing a NULL pointer dereference. This can lead to a denial of service by crashing the application using this library.
