Oracle Linux: CVE-2025-6069: ELSA-2025-23342: python3.9 security update (MODERATE) (Multiple Advisories)

A denial-of-service (DoS) vulnerability has been discovered in Python's html.parser.HTMLParser class. When processing specially malformed HTML input, the parsing runtime can become quadratic with respect to the input size. This significantly increased processing time can lead to excessive resource consumption, ultimately causing a denial-of-service condition in applications that rely on this parser.
