Moderate: gcc-toolset-11-gcc security update
Topic
An update is available for gcc-toolset-11-gcc.
This update affects Rocky Linux 8.
A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE list
Description
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.
