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

medium Nessus Plugin ID 181327

Language:

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.

 Customers building their own binaries with GCC are advised to update their compiler, and to ensure they are enabling the defense in depth options available to them, such as the stack protector.

Tenable has extracted the preceding description block directly from the tested product 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

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