Title: GCC: Flawed Code Generation
Date: September 24, 2024
Bugs: #719466
ID: 202409-22
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Synopsis
========
A vulnerability has been discovered in GCC, which can lead to flawed
code generation.
Background
==========
The GNU Compiler Collection includes front ends for C, C++, Objective-C,
Fortran, Ada, Go, D and Modula-2 as well as libraries for these
languages (libstdc++,...).
Affected packages
=================
Package Vulnerable Unaffected
------------- ------------ ------------
sys-devel/gcc < 10.0 >= 10.0
Description
===========
A vulnerability has been discovered in GCC. Please review the CVE
identifier referenced below for details.
Impact
======
The POWER9 backend in GNU Compiler Collection (GCC) could optimize
multiple calls of the __builtin_darn intrinsic into a single call, thus
reducing the entropy of the random number generator. This occurred
because a volatile operation was not specified. For example, within a
single execution of a program, the output of every __builtin_darn() call
may be the same.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All GCC users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=sys-devel/gcc-10.0"
And then select it with gcc-config:
# gcc-config latest
In this case, users should also rebuild all affected packages with
emerge -e, e.g.:
# emerge --usepkg=n --emptytree @world
