RedHat: RHSA-2021-4730:02 Moderate: Unicode Trojan Source Security Risk

An update for devtoolset-11-binutils is now available for Red Hat Software Collections. Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 ==================================================================== Red Hat Security Advisory Synopsis: Moderate: devtoolset-11-binutils security update Advisory ID: RHSA-2021:4730-01 Product: Red Hat Software Collections Advisory URL: https://access.redhat.com/errata/RHSA-2021:4730 Issue date: 2021-11-18 CVE Names: CVE-2021-42574 ==================================================================== 1. Summary: An update for devtoolset-11-binutils is now available for Red Hat Software Collections. 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 Software Collections for Red Hat Enterprise Linux Server (v. 7) - ppc64, ppc64le, s390x, x86_64 Red Hat Software Collections for Red Hat Enterprise Linux Server EUS (v. 7.7) - ppc64, ppc64le, s390x, x86_64 Red Hat Software Collections for Red Hat Enterprise Linux Workstation (v. 7) - x86_64 3. Description: The binutils packages provide a collection of binary utilities for the manipulation of object code in various object file formats. It includes the ar, as, gprof, ld, nm, objcopy, objdump, ranlib, readelf, size, strings, strip, and addr2line utilities. Security Fix(es): * Developer environment: Unicode's bidirectional (BiDi) override characterscan cause trojan source attacks (CVE-2021-42574) The following changes were introduced in binutils in order to facilitate detection of BiDi Unicode characters: Tools which display names or strings (readelf,strings, nm, objdump) have a new command line option --unicode / -U which controls how Unicode characters are handled. Using "--unicode=default" will treat them as normal for the tool. This is the default behaviour when --unicode option is not used. Using "--unicode=locale" will display them according to the current locale. Using "--unicode=hex" will display them as hex byte values. Using "--unicode=escape" will display them as Unicode escape sequences. Using "--unicode=highlight" will display them as Unicode escape sequences highlighted in red, if supported by the output device. 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. 4. Solution: For details on how to apply this update, which includes the changes described in this advisory, refer to: https://access.redhat.com/articles/11258 5.
