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

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

Impact
======

A remote attacker able to control the value passed to Rust's

arbitrary code when using rustdoc.

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-1.29.1"
