Amazon Linux 2023 : xmlrpc-c, xmlrpc-c-apps, xmlrpc-c-c++ (ALAS2023-2025-1229)

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2025-1229 advisory. libexpat through 2.5.0 allows a denial of service resource consumption because many full reparsings are required in the case of a large token for which multiple buffer fills are needed...

firefox: thunderbird: expat: libexpat in Expat allows attackers to trigger large dynamic memory allocations via a small document that is submitted for parsing

A memory amplification vulnerability in libexpat allows attackers to trigger excessive dynamic memory allocations by submitting specially crafted XML input. A small input 250 KiB can cause the parser to allocate hundreds of megabytes, leading to denial-of-service DoS through memory exhaustion...

Important: xmlrpc-c

Issue Overview: libexpat through 2.5.0 allows a denial of service resource consumption because many full reparsings are required in the case of a large token for which multiple buffer fills are needed. Considering the tradeoff between the stability of Amazon Linux and the impact of CVE-2023-52425...
