Am I affected?
Debian, Ubuntu or Red Hat sometimes backport a fix without changing the upstream version number: such a version reads « to verify », never « affected ».With a domain, we read the version its public headers and pages expose. A distribution build can carry the fix under an older number.
Description
An improper verification of cryptographic signature vulnerability was identified in GitHub Enterprise Server that allowed SAML SSO authentication to be bypassed resulting in unauthorized provisioning of users and access to the instance. Exploitation required the encrypted assertions feature to be enabled, and the attacker would require direct network access as well as a signed SAML response or metadata document. This vulnerability affected all versions of GitHub Enterprise Server prior to 3.15 and was fixed in versions 3.11.16, 3.12.10, 3.13.5, and 3.14.2. This vulnerability was reported via the GitHub Bug Bounty program.
