golang.org/x/crypto/ssh: golang.org/x/crypto/ssh: Denial of Service via crafted public key with excessive parameters

A flaw was found in golang.org/x/crypto/ssh. The RSA and DSA public key parsers in the affected component did not enforce size limits on key parameters. This vulnerability allows an unauthenticated client to provide a crafted public key with an excessively large modulus or DSA parameter during...

Infinite loop

Overview Affected versions of this package are vulnerable to Infinite loop due to logic errors in automatic certificate-based public key authentication, which can cause clients to enter an infinite loop in the authentication process. An attacker can cause resource exhaustion by configuring a serv...

CVE-2026-59849: Loop with Unreachable Exit Condition

A flaw was found in libssh. Logic errors in automatic certificate-based public key authentication can cause libssh clients to loop indefinitely when configured certificates are missing or repeatedly rejected by a server, leading to denial of service...

golang.org/x/crypto/ssh: golang.org/x/crypto/ssh: Authorization bypass due to skipped source-address validation

A flaw was found in golang.org/x/crypto/ssh. Source-address validation can be skipped when an SSH server configuration uses an authentication callback type other than public key, allowing authorization bypass in misconfigured servers. This is a follow-on to incomplete coverage from the...

PYSEC-2026-2384 AsyncSSH `AuthorizedKeysFile %u` path traversal allows attacker-selected authorized keys to authenticate a traversal username

Summary AsyncSSH 2.22.0 expands the OpenSSH-compatible AuthorizedKeysFile %u token with the raw SSH username during pre-authentication server config reload. A server configured with a documented per-user key pattern such as AuthorizedKeysFile authorizedkeys/%u can be made to read an authorized-ke...

golang.org/x/crypto: Invoking pathological RSA/DSA parameters may cause DoS

The RSA and DSA public key parsers did not enforce size limits on key parameters. A crafted public key with an excessively large modulus or DSA parameter could cause several minutes of CPU consumption during signature verification. This could be triggered by unauthenticated clients during public...
