Описание
mod_auth_openidc is an authentication and authorization module for the Apache 2.x HTTP server that implements the OpenID Connect Relying Party functionality. In versions 2.0.0 through 2.4.13.1, when OIDCStripCookies is set and a crafted cookie supplied, a NULL pointer dereference would occur, resulting in a segmentation fault. This could be used in a Denial-of-Service attack and thus presents an availability risk. Version 2.4.13.2 contains a patch for this issue. As a workaround, avoid using OIDCStripCookies.
A flaw was found in mod_auth_openidc, an OpenID Certified™ authentication and authorization module for the Apache HTTP server. It is possible to trigger a NULL pointer dereference when OIDCStripCookies is set and a crafted Cookie header is supplied, leading to a segmentation fault and a denial of service.
