8 April 2020

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

  o Ubuntu 18.04 LTS

Several security issues were fixed in libiberty.

Software Description

  o libiberty - library of utility functions used by GNU programs


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
