Buffa Vulnerable to Memory Exhaustion Denial of Service in decodeunknownfield via Unbounded Allocation...

CVE-2026-55406

Buffa is a pure-Rust Protocol Buffers implementation with first-class protobuf editions support. Prior to 0.7.0, a soundness bug in the OwnedView type allowed safe Rust code to trigger a use-after-free: the OwnedView::decode constructor transmuted a borrowed slice to &'static u8, and the Deref...

CVE-2026-55407

Buffa is a pure-Rust Protocol Buffers implementation with first-class protobuf editions support. Prior to 0.8.0, the decodeunknownfield function in buffa's protobuf decoder allocated heap memory in proportion to untrusted input unknown fields in the serialized protobuf without enforcing an...

CVE-2026-55407

CVE-2026-55407 affects Buffa, a pure-Rust Protocol Buffers implementation. Before v0.8.0, decode_unknown_field could allocate unbounded heap in response to untrusted input, causing memory amplification (e.g., a 64 MiB input could trigger ~1.4 GB). This impacts messages decoded with preserve_unkno...

CVE-2026-55406 Buffa: Use-After-Free in OwnedView via Unsound 'static Lifetime Promotion in Deref

Buffa is a pure-Rust Protocol Buffers implementation with first-class protobuf editions support. Prior to 0.7.0, a soundness bug in the OwnedView type allowed safe Rust code to trigger a use-after-free: the OwnedView::decode constructor transmuted a borrowed slice to &'static u8, and the Deref...

CVE-2026-55406

Buffa (Rust Protocol Buffers) prior to 0.7.0 contained a soundness flaw in OwnedView where OwnedView::decode transmuted a borrowed slice to &'static [u8] and the Deref promoted the static lifetime to borrowed view fields. This could let references outlive the OwnedView and, after drop, the backin...
