18 Jul 2024 — matrix-rust-sdk is an implementation of a Matrix client-server library in Rust. The `UserIdentity::is_verified()` method in the matrix-sdk-crypto crate before version 0.7.2 doesn't take into account the verification status of the user's own identity while performing the check and may as a result return a value contrary to what is implied by its name and documentation. If the method is used to decide whether to perform sensitive operations towards a user identity, a malicious homeserver could manipulate the ... • https://github.com/matrix-org/matrix-rust-sdk/commit/76a7052149bb8f722df12da915b3a06d19a6695a • CWE-287: Improper Authentication •

17 Jul 2024 — vodozemac is an open source implementation of Olm and Megolm in pure Rust. Versions before 0.7.0 of vodozemac use a non-constant time base64 implementation for importing key material for Megolm group sessions and `PkDecryption` Ed25519 secret keys. This flaw might allow an attacker to infer some information about the secret key material through a side-channel attack.

05 Jul 2024 — matrix-appservice-irc is a Node.js IRC bridge for the Matrix messaging protocol. The fix for GHSA-wm4w-7h2q-3pf7 / CVE-2024-32000 included in matrix-appservice-irc 2.0.0 relied on the Matrix homeserver-provided timestamp to determine whether a user has access to the event they're replying to when determining whether or not to include a truncated version of the original event in the IRC message.

https://notcve.org/view.php?id=CVE-2024-34353
13 May 2024 — The matrix-sdk-crypto crate, part of the Matrix Rust SDK project, is an implementation of a Matrix end-to-end encryption state machine in Rust. In Matrix, the server-side `key backup` stores encrypted copies of Matrix message keys. This facilitates key sharing between a user's devices and provides a redundant copy in case all devices are lost. The key backup uses asymmetric cryptography, with each server-side key backup assigned a unique public-private key pair. Due to a logic bug introduced in commit 71136... • https://crates.io/crates/matrix-sdk-crypto/0.7.1 • CWE-532: Insertion of Sensitive Information into Log File •

03 May 2024 — vodozemac is an implementation of Olm and Megolm in pure Rust. Versions 0.5.0 and 0.5.1 of vodozemac have degraded secret zeroization capabilities, due to changes in third-party cryptographic dependencies (the Dalek crates), which moved secret zeroization capabilities behind a feature flag and defaulted this feature to off. The degraded zeroization capabilities could result in the production of more memory copies of encryption secrets and secrets could linger in memory longer than necessary. This marginally... • https://github.com/matrix-org/vodozemac/commit/297548cad4016ce448c4b5007c54db7ee39489d9 • CWE-1188: Initialization of a Resource with an Insecure Default •

12 Apr 2024 — matrix-appservice-irc is a Node.js IRC bridge for the Matrix messaging protocol. matrix-appservice-irc before version 2.0.0 can be exploited to leak the truncated body of a message if a malicious user sends a Matrix reply to an event ID they don't have access to. As a precondition to the attack, the malicious user needs to know the event ID of the message they want to leak, as well as to be joined to both the Matrix room and the IRC channel it is bridged to.

31 Oct 2023 — Synapse is an open-source Matrix homeserver Prior to versions 1.95.1 and 1.96.0rc1, cached device information of remote users can be queried from Synapse. This can be used to enumerate the remote users known to a homeserver. System administrators are encouraged to upgrade to Synapse 1.95.1 or 1.96.0rc1 to receive a patch. As a workaround, the `federation_domain_whitelist` can be used to limit federation traffic with a homeserver.
