Apache Filter & Weblogin Server:
WARNING: Versions of cosign older than 3.0 have an architectural flaw (detailed here). New users of cosign should select the latest cosign 3 release for download. Existing legacy cosign installations should upgrade to cosign 3 as soon as possible. An overview of that process may be found here.
WARNING: Versions of the cosign weblogin server
prior to 2.0.2a (excluding 1.9.4b) contain remotely
exploitable security vulnerabilities. The cosign
development team strongly recommends that only newer
versions of the cosign weblogin server be used.
