Oracle Linux 7 : unbreakable enterprise kernel (ELSA-2014-3049)
high Nessus Plugin ID 76781

Synopsis
The remote Oracle Linux host is missing one or more security updates.Description
The remote Oracle Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2014-3049 advisory.- The PPPoL2TP feature in net/l2tp/l2tp_ppp.c in the Linux kernel through 3.15.6 allows local users to gain privileges by leveraging data-structure differences between an l2tp socket and an inet socket.
(CVE-2014-4943)
- The Linux kernel before 3.15.4 on Intel processors does not properly restrict use of a non-canonical value for the saved RIP address in the case of a system call that does not use IRET, which allows local users to leverage a race condition and gain privileges, or cause a denial of service (double fault), via a crafted application that makes ptrace and fork system calls. (CVE-2014-4699)
- The skb_flow_dissect function in net/core/flow_dissector.c in the Linux kernel through 3.12 allows remote attackers to cause a denial of service (infinite loop) via a small value in the IHL field of a packet with IPIP encapsulation. (CVE-2013-4348)
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
