Amazon Linux 2023 : cpp, gcc, gcc-c++ (ALAS2023-2023-342)

medium Nessus Plugin ID 181327

Synopsis

The remote Amazon Linux 2023 host is missing a security update.

Description

It is, therefore, affected by a vulnerability as referenced in the ALAS2023-2023-342 advisory.

- An issue was found in a defense in depth feature of the GCC compiler on aarch64 platforms. The stack protector feature (-fstack-protector) did not detect or defend against overflows of dynamically-sized local variables. This update to the GCC compiler remedies code generation for this defense in depth feature, ensuring it is working as intended. (CVE-2023-4039)

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

Solution

Run 'dnf update gcc --releasever 2023.1.20230912' to update your system.
