Описание
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.
Меры по смягчению последствий
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
