Ubuntu 14.04 LTS : libseccomp vulnerability (USN-4001-2)

critical Nessus Plugin ID 125625

Language:

Synopsis

The remote Ubuntu host is missing a security-related patch.

Description

USN-4001-1 fixed a vulnerability in libseccomp. This update provides the corresponding update for Ubuntu 14.04 ESM.

Original advisory details :

Jann Horn discovered that libseccomp did not correctly generate 64-bit syscall argument comparisons with arithmetic operators (LT, GT, LE, GE). An attacker could use this to bypass intended access restrictions for argument-filtered system calls.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected libseccomp2 package.
