Previously, a revoked 'SignatureKey' belonging to a CA was not correctly checked for revocation.

Previously, CVE-2024-45337 fixed an authorization bypass for misused ssh server configurations; if any other type of callback is passed other than public key, then the source-address validation would be skipped.

The in-memory keyring returned by NewKeyring() silently accepted keys with the ConfirmBeforeUse constraint but never enforced it.

When adding a key to a remote agent constraint extensions such as [email protected] were not serialized in the request.

The ToASCII and ToUnicode functions incorrectly accept Punycode-encoded labels that decode to an ASCII-only label.

A malicious SSH peer could send unsolicited global request responses to fill an internal buffer, blocking the connection's read loop.

Pathological inputs could cause DoS through consumePhrase when parsing an email address according to RFC 5322.

Well-crafted inputs reaching ParseAddress, ParseAddressList, and ParseDate were able to trigger excessive CPU exhaustion and memory allocations.

When using LookupCNAME with the cgo DNS resolver, a very long CNAME response can trigger a double-free of C memory and a crash.

Prometheus is an open-source monitoring system and time series database.

The RSA and DSA public key parsers did not enforce size limits on key parameters.

(*x509.Certificate).VerifyHostname previously called matchHostnames in a loop over all DNS Subject Alternative Name (SAN) entries.

When an SSH server authentication callback returned PartialSuccessError with non-nil Permissions, those permissions were silently discarded, potentially dropping certificate restrictions such as force-command after a sec…

SSH servers which use CertChecker as a public key callback without setting IsUserAuthority or IsHostAuthority could be caused to panic by a client presenting a certificate.
