DeepGuard: Defending Deep Joint Source-Channel Coding against Eavesdropping at Physical-Layer

Deep joint source-channel coding DeepJSCC has emerged as a promising paradigm for efficient and robust information transmission. However, its intrinsic characteristics also pose new security challenges, notably an increased vulnerability to eavesdropping attacks. Existing studies on defending...

Denial Of Service

rack is vulnerable to Denial Of Service. The vulnerability is due to unbounded buffering of the multipart preamble in Rack::Multipart::Parser, where attackers can send extremely large preamble data before the first boundary, causing excessive memory consumption and potential OOM-induced DoS...

rack: Rack's unbounded multipart preamble buffering enables DoS (memory exhaustion)

A flaw was found in Rack where the Rack::Multipart::Parser buffers the multipart preamble memory without size limits. A remote attacker can send a crafted multipart/form-data request with a very large preamble before its first boundary, causing excessive memory consumption and denial of service...
