Date: Wed, 16 Jul 2014 22:50:37 -0700 From: Kees Cook <kees@...flux.net> To: oss-security@...ts.openwall.com Subject: CVE-2014-4943: Linux privilege escalation in ppp over l2tp sockets CVE-2014-4943 is a flaw in the Linux kernel allowing an unprivileged user to escalate to kernel privilege when CONFIG_PPPOL2TP is enabled. If built as a module, a work-around to limit this to just the root user would be to add this to /etc/modprobe.conf: alias pppox-proto-1 off blacklist l2tp_ppp Upstream commit: https://git.kernel.org/linus/3cf521f7dc87c031617fd47e4b7aa2593c2f3daf -Kees -- Kees Cook @outflux.net
