org.apache.qpid/proton-j: Apache Qpid Proton-J: Denial of Service due to excessive allocation

A flaw was found in Apache Qpid Proton-J. A remote attacker, without needing to authenticate, could exploit a vulnerability in how the software handles type sizes and counts. This could lead to excessive memory allocation, causing the system to become unresponsive and resulting in a denial of...

io.netty/netty-codec-http: Netty: Denial of Service via SPDY SETTINGS frame processing

A flaw was found in Netty, a network application framework. A remote attacker, by sending a specially crafted SPDY/3.1 SETTINGS frame, could cause the SPDY SETTINGS decoder to create a large number of map entries. This excessive processing and memory allocation can lead to a denial of service DoS...
