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.
