kernel: af_unix: Set gc_in_progress to true in unix_gc()

A flaw was found in the Linux kernel's afunix component. A race condition exists within the unixgc garbage collection function where the gcinprogress flag may not be correctly set. This could lead to unixpeekfpl misinterpreting garbage collection status when handling MSGPEEK operations, potential...

stomper 5e2741e is vulnerable to Denial of Service. A malicious client can send partial STOMP frames and keep the TCP connections open, which, combined with the broker s use of edge-triggered epoll EPOLLET and MSGPEEK in recv, causes sockets to enter a permanent half-read state. When enough such...
