Synopsis
========

Multiple vulnerabilities have been discovered in Rust, the worst of
which could result in denial of service.

Background
==========

A systems programming language that runs blazingly fast, prevents
segfaults, and guarantees thread safety.

Affected packages
=================

    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
  1  dev-lang/rust              < 1.63.0-r1              >= 1.63.0-r1
  2  dev-lang/rust-bin          < 1.64.0                    >= 1.64.0

Description
===========

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

Impact
======

Please review the referenced CVE identifiers for details.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All Rust users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=dev-lang/rust-1.63.0-r1"

All Rust binary users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=dev-lang/rust-bin-1.64.0"

In addition, users using Portage 3.0.38 or later should ensure that
packages with Rust binaries have no vulnerable code statically linked
into their binaries by rebuilding the @rust-rebuild set:

  # emerge --ask --oneshot --verbose @rust-rebuild
