Summary

libseccomp vulnerability

Details

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.
