Ubuntu 14.04 LTS : Linux kernel vulnerabilities (USN-3083-1)

high Nessus Plugin ID 93602

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 14.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-3083-1 advisory.

- net/sctp/sm_sideeffect.c in the Linux kernel before 4.3 does not properly manage the relationship between a lock and a socket, which allows local users to cause a denial of service (deadlock) via a crafted sctp_accept call. (CVE-2015-8767)

- The IPv6 stack in the Linux kernel before 4.3.3 mishandles options data, which allows local users to gain privileges or cause a denial of service (use-after-free and system crash) via a crafted sendmsg system call. (CVE-2016-3841)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected kernel package.
