An update for mod_auth_openidc is now available for openEuler-22.03-LTS-SP3 Security Advisory openeuler-security@openeuler.org openEuler security committee openEuler-SA-2024-1194 Final 1.0 1.0 2024-02-23 Initial 2024-02-23 2024-02-23 openEuler SA Tool V1.0 2024-02-23 mod_auth_openidc security update An update for mod_auth_openidc is now available for openEuler-22.03-LTS-SP3. This module enables an Apache 2.x web server to operate as an OpenID Connect Relying Party(RP) to an OpenID Connect Provider(OP). Security Fix(es): mod_auth_openidc is an OpenID Certified™ authentication and authorization module for the Apache 2.x HTTP server that implements the OpenID Connect Relying Party functionality. In affected versions missing input validation on mod_auth_openidc_session_chunks cookie value makes the server vulnerable to a denial of service (DoS) attack. An internal security audit has been conducted and the reviewers found that if they manipulated the value of the mod_auth_openidc_session_chunks cookie to a very large integer, like 99999999, the server struggles with the request for a long time and finally gets back with a 500 error. Making a few requests of this kind caused our server to become unresponsive. Attackers can craft requests that would make the server work very hard (and possibly become unresponsive) and/or crash with minimal effort. This issue has been addressed in version 2.4.15.2. Users are advised to upgrade. There are no known workarounds for this vulnerability.(CVE-2024-24814) An update for mod_auth_openidc is now available for openEuler-22.03-LTS-SP3. openEuler Security has rated this update as having a security impact of high.
