Описание
An issue was discovered in libexpat before 2.6.4. There is a crash within the XML_ResumeParser function because XML_StopParser can stop/suspend an unstarted parser.
A security issue was found in Expat (libexpat). A crash can be triggered in the XML_ResumeParser function due to XML_StopParser's ability to stop or suspend an unstarted parser, which can lead to a denial of service.
Отчет
Within regulated environments, a combination of the following controls acts as a significant barrier to successfully exploiting a CWE-754: Improper Check for Unusual or Exceptional Conditions vulnerability and therefore downgrades the severity of this particular CVE from Moderate to Low. The platform enforces hardening guidelines to apply the most restrictive settings required for operations, while baseline configurations maintain secure system and software states. A defense-in-depth monitoring strategy includes perimeter firewalls and endpoint protection services that detect and respond to indicators in real time, enabling logging and auditing of system behavior to identify and address improper exception handling. Automated integrity checks alert on unverified exception-related errors, while memory protection mechanisms reduce the risk of crashes or vulnerabilities caused by improper handling.
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.
