USN-8790-1: Expat vulnerabilities

It was discovered that Expat could be made to allocate large amounts of memory when parsing a small crafted document. An attacker could possibly use this issue to cause Expat to consume resources, leading to a denial of service. This issue was only addressed in Ubuntu 24.04 LTS. CVE-2025-59375 It...

python: Python/Expat: Denial of Service via crafted XML document

A flaw was found in the python and expat components. Insufficient entropy in the hash-flooding protection mechanism of xml.parsers.expat and xml.etree.ElementTree allows a remote attacker to craft a malicious XML document. This crafted document can trigger a hash flooding attack, leading to a...
