==========================================================================

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

- Ubuntu 18.04 LTS

Summary:

Several security issues were fixed in GNU binutils.

Software Description:
- binutils: GNU assembler, linker and binary utilities

Details:

It was discovered that GNU binutils contained a large number of security
issues. If a user or automated system were tricked into processing a
specially-crafted file, a remote attacker could cause GNU binutils to
crash, resulting in a denial of service, or possibly execute arbitrary
code.

Update instructions:

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