Description
Multiple critical security vulnerabilities have been identified in the Go programming language (golang) affecting versions prior to 1.21.4-53.oe2403sp3. These include denial of service issues in certificate chain verification, memory exhaustion via HTTP/2 Trailer headers, flow control bypass in HTTP/2, excessive CPU consumption from SETTINGS frames, improper handling of HTTP/1 CONNECT responses leading to potential request smuggling, checksum bypass in module proxy verification, and server crashes due to concurrent HPACK encoder modifications. These vulnerabilities collectively impact the integrity and availability of applications using affected Go versions.
