Описание
xml.parsers.expat and xml.etree.ElementTree use insufficient entropy for Expat hash-flooding protection, which allows a crafted XML document to trigger hash flooding.\r\n\r\nFully mitigating this vulnerability requires both updating libexpat to 2.8.0 or later and applying this patch.
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 denial of service (DoS) condition.
Отчет
The impact from this flaw is limited to a denial of service in the Python runtime. Host Red Hat systems are not affected in their default configurations.
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.
