On s390 systems, an unprivileged local user could use this flaw to set address space control bits to kernel space combination and thus gain read/write access to kernel memory. CVE-2014-4667 Gopal Reddy Kodudula of Nokia Siemens Networks discovered that the sctp_association_free function does not properly manage a certain backlog value, which allows remote attackers to cause a denial of service (socket outage) via a crafted SCTP packet. CVE-2014-4943 Sasha Levin discovered a flaw in the Linux kernel's point-to-point protocol (PPP) when used with the Layer Two Tunneling Protocol (L2TP). An unprivileged local user could use this flaw for privilege escalation. For the stable distribution (wheezy), these problems have been fixed in version 3.2.60-1+deb7u3. For the unstable distribution (sid), these problems have been fixed in version 3.14.13-2. We recommend that you upgrade your linux packages.
