Synopsis
=======
Multiple vulnerabilities have been found in CyaSSL, the worst of which
may allow attackers to execute arbitrary code.

Background
=========
CyaSSL is a small, fast, portable implementation of TLS/SSL for
embedded devices to the cloud.

Affected packages
================
    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
  1  net-libs/cyassl             *<= 2.9.4                 Vulnerable!
    -------------------------------------------------------------------
     NOTE: Certain packages are still vulnerable. Users should migrate
           to another package if one is available or wait for the
           existing packages to be marked stable by their
           architecture maintainers.

Description
==========
Multiple vulnerabilities have been discovered in CyaSSL. Please review
the CVE identifiers referenced below for details.

Impact
=====
An attacker could possibly execute arbitrary code with the privileges
of the process, cause a Denial of Service condition, or conduct a
man-in-the-middle attack.

Workaround
=========
There is no known workaround at this time.

Resolution
=========
Upstream has discontinued the software in favor of wolfSSL. Therefore,
the CyaSSL package has been removed from the Gentoo repository and
current users are advised to unmerge the package.

  # emerge --unmerge "net-libs/cyassl"
