libiberty vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 18.04 LTS
- Ubuntu 16.04 LTS

Summary:

Several security issues were fixed in libiberty.

Software Description:
- libiberty: library of utility functions used by GNU programs

Details:

It was discovered that libiberty incorrectly handled parsing certain
binaries. If a user or automated system were tricked into processing a
specially crafted binary, a remote attacker could use this issue to cause
libiberty to crash, resulting in a denial of service, or possibly execute
arbitrary code

The problem can be corrected by updating your system to the following
package versions:
