Amazon Linux 2 : gcc (ALAS-2023-2245)

medium Nessus Plugin ID 181359

Language:

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of gcc installed on the remote host is prior to 7.3.1-17. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2023-2245 advisory.

 2023-09-13: The severity of this advisory was corrected from low to medium.

 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. (CVE-2023-4039)

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 'yum update gcc' to update your system.
