netty-handler: netty-handler: IPv6 subnet rule bypass due to incorrect masking operation

A flaw was found in netty-handler, a component of the Netty network application framework. A remote attacker can exploit an incorrect masking operation in the IpSubnetFilterRule.compareTo function to bypass configured IPv6 subnet rules. This allows valid public IP addresses to circumvent intended...

netty-handler: Netty: Denial of Service due to eager buffer allocation in TLS handshake

A flaw was found in Netty, a network application framework. A remote attacker can exploit this vulnerability by sending a crafted TLS Transport Layer Security ClientHello message. This can lead to an eager allocation of a large memory buffer, causing a Denial of Service DoS due to excessive memor...

netty: io.netty/netty-codec-http: io.netty/netty-codec-http2: Netty: Denial of Service via unbounded memory allocation in HTTP content decompression

A flaw was found in Netty. A remote attacker can bypass the configured decompression limit in the HttpContentDecompressor by sending a specially crafted compressed payload using Brotli br, Zstandard zstd, or Snappy content encodings. This can lead to unbounded memory allocation, resulting in an...

io.netty/netty-codec-http: Netty: Request smuggling via incorrect parsing of HTTP/1.1 chunked transfer encoding extension values

A flaw was found in Netty. A remote attacker could exploit this vulnerability by sending specially crafted HTTP/1.1 chunked transfer encoding extension values. Due to incorrect parsing of quoted strings, this flaw enables request smuggling attacks, potentially allowing an attacker to bypass...

netty: io.netty/netty-codec-http: Netty: Incorrect HTTP response parsing leads to data confusion

A flaw was found in Netty, an asynchronous, event-driven network application framework.
