undici: undici: Denial of Service via unbounded decompression of compressed responses

A flaw was found in undici. The decompress interceptor in undici processes compressed response bodies based on the untrusted Content-Encoding header. A remote attacker can exploit this by sending a small, specially crafted compressed payload, known as a 'compression bomb,' which expands...

io.netty/netty-codec-compression: Netty: Infinite loop in netty-codec-compression (bzip2)

A flaw was found in the netty-codec-compression component of Netty. This vulnerability, caused by a logic error in the bzip2 decoder, allows a remote attacker to send specially crafted bzip2-compressed data. Processing this malformed data can trigger an infinite loop, causing the decoder thread t...

github.com/klauspost/compress: klauspost/compress: Denial of Service via integer overflow in dictionary processing

A flaw was found in the klauspost/compress package. A remote attacker can exploit this vulnerability by supplying a specially crafted compression dictionary with an excessively large repeat value, triggering an integer overflow. When the dictionary is subsequently processed, this overflow leads t...
