3. Description:
The GNU Compiler Collection (GCC) is a portable compiler suite with support
for various programming languages, including C, C++, and Fortran. The
devtoolset-11-gcc packages provide the Red Hat Developer Toolset version of
GCC, as well as related 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.
