Описание
A flaw was found in libxml2's xmlBuildQName function, where integer overflows in buffer size calculations can lead to a stack-based buffer overflow. This issue can result in memory corruption or a denial of service when processing crafted input.
Отчет
This vulnerability is rated Moderate due to the lack of confidentiality impact and limited integrity concerns, with the main risk being potential denial-of-service from a crash. Exploitation requires crafted XML input and specific application behavior using xmlBuildQName. While it’s a write overflow, modern mitigations make remote code execution unlikely.
Меры по смягчению последствий
Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability. Users are strongly advised to apply vendor-supplied patches as soon as they become available to address the underlying integer overflow flaw in the affected code.
