This update for gcc7 to r275405 fixes the following issues :

Security issues fixed :

CVE-2019-14250: Fixed an integer overflow in binutils (bsc#1142649).

CVE-2019-15847: Fixed an optimization in the POWER9 backend of gcc that could reduce the entropy of the random number generator (bsc#1149145).

Non-security issue fixed: Move Live Patching technology stack from kGraft to upstream klp (bsc#1071995, fate#323487).

The remote Oracle Linux 8 host has packages installed that are affected by a vulnerability as referenced in the ELSA-2020-1864 advisory.

  - The POWER9 backend in GNU Compiler Collection (GCC) before version 10 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. (CVE-2019-15847)

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

This update for gcc9 fixes the following issues :

The GNU Compiler Collection is shipped in version 9.

A detailed changelog on what changed in GCC 9 is available at https://gcc.gnu.org/gcc-9/changes.html

The compilers have been added to the SUSE Linux Enterprise Toolchain Module.

To use these compilers, install e.g. gcc9, gcc9-c++ and build with CC=gcc-9 CXX=g++-9 set.

For SUSE Linux Enterprise base products, the libstdc++6, libgcc_s1 and other compiler libraries have been switched from their gcc8 variants to their gcc9 variants.

Security issues fixed :

CVE-2019-15847: Fixed a miscompilation in the POWER9 back end, that optimized multiple calls of the __builtin_darn intrinsic into a single call. (bsc#1149145)

CVE-2019-14250: Fixed a heap overflow in the LTO linker. (bsc#1142649)

Non-security issues fixed: Split out libstdc++ pretty-printers into a separate package supplementing gdb and the installed runtime.
(bsc#1135254)

Fixed miscompilation for vector shift on s390. (bsc#1141897)
