high Nessus Plugin ID 291654

Synopsis

The remote MiracleLinux host is missing a security update.

Description

The remote MiracleLinux 8 host has packages installed that are affected by a vulnerability as referenced in the AXSA:2021-2879:01 advisory.

 * Developer environment: Unicode's bidirectional (BiDi) override characters can cause trojan source attacks (CVE-2021-42574) The following changes were introduced in gcc in order to facilitate detection of BiDi Unicode characters:
 This update implements a new warning option -Wbidirectional to warn about possibly dangerous bidirectional characters.
 There are three levels of warning supported by gcc:
 -Wbidirectional=unpaired, which warns about improperly terminated BiDi contexts. (This is the default.)
 -Wbidirectional=none, which turns the warning off.
 -Wbidirectional=any, which warns about any use of bidirectional characters.

Tenable has extracted the preceding description block directly from the MiracleLinux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected gcc-toolset-10-binutils and / or gcc-toolset-10-binutils-devel packages.
