A gcc-toolset-10-binutils security update has been released for AlmaLinux.

ALSA-2021:4649 Moderate: gcc-toolset-10-binutils security update

Type:
security

Severity:
moderate

Release date:
2021-11-16

Description
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 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.
