Synopsis

The remote Red Hat host is missing a security update for devtoolset-9-gcc.

Description

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2020:2274 advisory.

The GNU Compiler Collection (GCC) is a portable compiler suite with support for various programming languages, including C, C++, and Fortran. The devtoolset-9-gcc packages provide the Red Hat Developer Toolset version of GCC, as well as related libraries.

The following packages have been upgraded to a later upstream version: devtoolset-9-gcc (9.3.1).

Security Fix(es):

* gcc: POWER9 DARN RNG intrinsic produces repeated output (CVE-2019-15847)

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.

Bug Fix(es):

* Compiler vectorizes the loop incorrectly when the loop is inlined (BZ#1769410)

* Update gcc for DTS 9.1 RHEL 7 (BZ#1783475)

* g++ rejects a valid code (BZ#1802608)

* Update gcc for DTS 9.1 from upstream GCC 9.3 (BZ#1812147)

Additional Changes:

For detailed changes in this release, see the Red Hat Developer Toolset 9.1 User Guide linked from the References section.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

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

Solution

Update the RHEL devtoolset-9-gcc package based on the guidance in RHSA-2020:2274.
