russh: Client-side channel-scoped Handler callbacks fire for channel IDs the client never opened

Russh: SSH message fields were decoded through allocation-first parsers before field-specific bounds

Russh: Post-decompression SSH packet size was not bounded, allowing remote oversized compressed packets

Russh: Unchecked CryptoVec allocation and growth handling is reachable from local agent inputs in current russh releases and from remote SSH traffic in historical pre-0.58.0 releases

Russh: Pre-auth DoS via unbounded allocation in keyboard-interactive auth

Russh: Unbounded memory exhaustion via CHANNEL_OPEN flood during a client-stalled rekey

Russh: Channel-scoped server callbacks can be reached without an open channel

Russh: Unchecked keyboard-interactive prompt count in client auth path

pageant: Out-of-bounds read / oversized allocation in `pageant` MemoryMap::read via a malicious Pageant agent (Windows)

Russh: Pre-auth remote panic via all-zero Curve25519 peer public value (encode_mpint OOB)

Russh: client wrong-length X25519 `clone_from_slice` panic (pre-auth DoS)

Russh: SSH identification parsing accepted non-canonical client banners and did not bound pre-banner input

russh server userauth state is not reset when authentication principal changes

russh: peer-declared zero maximum packet size permanently stalls channel writes (silent AsyncWrite hang)

russh's SSH client is susceptible to unbounded allocations via EXT_INFO packets

russh agent server converts constraint records into unbounded never-rolled-back tasks

Russh: Missing X25519 zero-point validation in hybrid ML-KEM key exchange

Russh: Post-auth remote panic via pty-req with more than 130 terminal-mode records

Russh: Configured server auth-attempt cap is not enforced in the USERAUTH_REQUEST runtime path

russh: negotiating a MAC-requiring block cipher (CTR/CBC) with mac=none causes a slice-index-out-of-range panic

russh's SSH agent server is susceptible to unbound allocations via repeated SSH_AGENT_CONSTRAIN_CONFIRM messages

pageant: unbounded frame buffering on peer-controlled 4-byte length prefix (memory-exhaustion DoS)
