[ALSA-2021:4587] Moderate: gcc security update
Release date:
The gcc packages provide compilers for C, C++, Java, Fortran, Objective C, and Ada 95 GNU, as well as related support 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 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. 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.
