| Description | A flaw was found in the SPDY streaming code used by Kubelet, CRI-O, and kube-apiserver. An attacker with specific cluster roles, such as those allowing access to pod port forwarding, execution, or attachment, or node proxying, could exploit this vulnerability. This could lead to a Denial of Service (DoS) by causing the affected components to become unresponsive. | spdystream is a Go library for multiplexing streams over SPDY connections. In versions 0.5.0 and below, the SPDY/3 frame parser does not validate attacker-controlled counts and lengths before allocating memory. Three allocation paths are affected: the SETTINGS frame entry count, the header count in parseHeaderValueBlock, and individual header field sizes — all read as 32-bit integers and used directly as allocation sizes with no bounds checking. Because SPDY header blocks are zlib-compressed, a small on-the-wire payload can decompress into large attacker-controlled values. A remote peer that can send SPDY frames to a service using spdystream can exhaust process memory and cause an out-of-memory crash with a single crafted control frame. This issue has been fixed in version 0.5.1. |
