Red Hat Bugzilla – Bug 1297813
CVE-2013-4312 kernel: File descriptors passed over unix sockets are not properly accounted
Last modified: 2018-08-28 18:01:55 EDT
It was found that process could allocate and accumulate far more FDs than the process' limit by sending them over a unix socket then closing them to keep the process' fd count low, which could result into a local DoS against kernel by depleting all available memory.
