AI-suggested
A patch is available and should be applied to affected libexpat versions. Ubuntu and Red Hat have released fixed package versions to address this vulnerability. Red Hat's builds use the -fstack-clash-protection compiler flag, which mitigates the risk of arbitrary code execution, limiting the impact to denial of service. Users should update to the fixed versions listed in the vendor advisories. No additional mitigations are currently recommended or available.
Description
CVE-2024-8176 is a stack overflow vulnerability in the libexpat XML parsing library caused by recursive entity expansion in XML documents. Deeply nested entity references can cause libexpat to recurse indefinitely, exhausting stack space and crashing the application. This can lead to denial of service (DoS) or potentially exploitable memory corruption depending on environment and usage. The vulnerability has a high severity score of 7.5 and affects multiple versions of libexpat. Fixes are available in updated package versions.
