Source: libapache2-mod-auth-openidc Version: 2.4.4.1-2 Severity: important Tags: security upstream X-Debbugs-Cc: car...@debian.org, Debian Security Team <t...@security.debian.org>
Hi, The following vulnerability was published for libapache2-mod-auth-openidc. CVE-2021-32791[0]: | mod_auth_openidc is an authentication/authorization module for the | Apache 2.x HTTP server that functions as an OpenID Connect Relying | Party, authenticating users against an OpenID Connect Provider. In | mod_auth_openidc before version 2.4.9, the AES GCM encryption in | mod_auth_openidc uses a static IV and AAD. It is important to fix | because this creates a static nonce and since aes-gcm is a stream | cipher, this can lead to known cryptographic issues, since the same | key is being reused. From 2.4.9 onwards this has been patched to use | dynamic values through usage of cjose AES encryption routines. If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
