Linux kernel access restriction bypass vulnerability

Linux kernel is the kernel used by Linux, the open source operating system released by the Linux Foundation in the United States. A security vulnerability exists in the net/netfilter/nfnetlinkcthelper.c file in Linux kernel 4.14.4 and earlier, which stems from the nfnlcthelperlist data structure...

CVE-2016-3708

Red Hat OpenShift Enterprise 3.2, when multi-tenant SDN is enabled and a build is run in a namespace that would normally be isolated from pods in other namespaces, allows remote authenticated users to access network resources on restricted pods via an s2i build with a builder image that 1 contain...

kernel: 'kill sig -1' must only apply to caller's pid namespace

The killsomethinginfo function in kernel/signal.c in the Linux kernel before 2.6.28 does not consider PID namespaces when processing signals directed to PID -1, which allows local users to bypass the intended namespace isolation, and send arbitrary signals to all processes in all namespaces, via ...

CVE-2009-1338

The killsomethinginfo function in kernel/signal.c in the Linux kernel before 2.6.28 does not consider PID namespaces when processing signals directed to PID -1, which allows local users to bypass the intended namespace isolation, and send arbitrary signals to all processes in all namespaces, via ...

CVE-2009-1338

The CVE-2009-1338 issue is confirmed in the Linux kernel prior to 2.6.28, where the kill_something_info() function in kernel/signal.c did not respect PID namespaces when handling signals directed to PID -1. This allowed a local attacker to bypass namespace isolation and send signals to processes ...
