Red Hat Security Advisory
Synopsis: Moderate: rust-toolset:rhel8 security update
Advisory ID: RHSA-2021:4590-01
Product: Red Hat Enterprise Linux
Advisory URL: https://access.redhat.com/errata/RHSA-2021:4590

=====================================================================
1. Summary:
An update for the rust-toolset:rhel8 module is now available for Red Hat
Enterprise Linux 8.
Red Hat Product Security has rated this update as having a security impact
of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which
gives a detailed severity rating, is available for each vulnerability from
the CVE link(s) in the References section.
2. Relevant releases/architectures:
Red Hat Enterprise Linux AppStream (v. 8) - aarch64, noarch, ppc64le, s390x, x86_64
3. Description:
Rust Toolset provides the Rust programming language compiler rustc, the
cargo build tool and dependency manager, and required libraries.
Security Fix(es):
* Developer environment: Unicode's bidirectional (BiDi) override characters
can cause trojan source attacks (CVE-2021-42574)
The following changes were introduced in rust in order to facilitate
detection of BiDi Unicode characters:
Rust introduces two new lints to detect and reject code containing the
affected codepoints. These new deny-by-default lints detect affected
codepoints in string literals and comments. The lints will prevent source
code file containing these codepoints from being compiled. If your code has
legitimate uses for the codepoints we recommend replacing them with the
related escape sequence. The error messages will suggest the right escapes
to use.
For more details about the security issue(s), including the impact, a CVSS
score, acknowledgments, and other related information, refer to the CVE
page(s) listed in the References section.
