New! Plugin Severity Now Using CVSS v3
The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.
Synopsis
The remote Oracle Linux host is missing one or more security updates.Description
The remote Oracle Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2014-3046 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.
