golang.org/x/crypto/ssh/agent: golang.org/x/crypto/ssh/agent: Security bypass due to improper handling of key restrictions

A flaw was found in golang.org/x/crypto/ssh/agent. When a key was added to a remote agent, security restrictions, known as constraint extensions, were not properly processed during the request. This allowed these restrictions to be silently removed when keys were forwarded, leading to the...

golang.org/x/crypto/ssh/knownhosts: golang: golang.org/x/crypto/ssh/knownhosts: Revocation bypass via unchecked SignatureKey

A flaw was found in golang.org/x/crypto/ssh/knownhosts. This vulnerability occurs because the system did not correctly check for the revocation status of a SignatureKey belonging to a Certificate Authority CA. A remote attacker could potentially exploit this by presenting a revoked key, leading t...

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...

SUSE CVE-2026-41678

rust-openssl provides OpenSSL bindings for the Rust programming language. From to before 0.10.78, aes::unwrapkey contains an incorrect assertion: it checks that out.len + 8 = in.len - 8, ensuring the output buffer is large enough. Because of the inverted check, the function only accepts buffers a...
