Name of the Vulnerable Software and Affected Versions expat versions prior to 2.1.0

Description The issue is related to multiple vulnerabilities in the expat package, which can lead to a disruption of protected information availability. These vulnerabilities can be exploited remotely. A memory leak in the poolGrow function in expat/lib/xmlparse.c allows context-dependent attackers to cause a denial of service (memory consumption) via a large number of crafted XML files that cause improperly-handled reallocation failures when expanding entities.

Recommendations For expat versions prior to 2.1.0, update to version 2.1.0 or later to resolve the issue. As a temporary workaround, consider restricting the processing of XML files to minimize the risk of exploitation. Avoid using the poolGrow function in the expat/lib/xmlparse.c file until the issue is resolved.
