Using an affected version of MicroStation or MicroStation-based application to open a 3DS file containing crafted data can force an out-of-bounds read. Exploitation of these vulnerabilities within the parsing of IFC files could enable an attacker to read information in the context of the current process.Īn issue was discovered in Bentley MicroStation before 10.17.0.x and Bentley View before 10.17.0.x. Using an affected version of MicroStation or MicroStation-based application to open an IFC file containing crafted data can force an out-of-bounds read. Exploitation of these vulnerabilities within the parsing of FBX files could enable an attacker to read information in the context of the current process.Īn issue was discovered in Bentley MicroStation before 10.17.0.x and Bentley View before 10.17.0.x.

Users unable to upgrade are advised to filter websocket traffic externally or to only accept trusted traffic.Īn issue was discovered in Bentley MicroStation before 10.17.0.x and Bentley View before 10.17.0.x. Affected users are advised to update to this version. The crashes are fixed in version 0.26.5 by imposing default dataframe size limits. Async version also does not limit memory, but does not use `with_capacity`, so DoS can happen only when bytes for oversized dataframe or message actually got delivered by the attacker.

This affects only sync (non-Tokio) implementation. When `Vec::with_capacity` fails to allocate, the default Rust allocator will abort the current process, killing all threads.

Affected versions would allocate a buffer based on the declared dataframe size, which may come from an untrusted source. The root cause of the issue is during dataframe parsing. In versions prior to 0.26.5 untrusted websocket connections can cause an out-of-memory (OOM) process abort in a client or a server. Rust-WebSocket is a WebSocket (RFC6455) library written in Rust.
