Echo: gcc-12: security update to 12.2.0-14

medium Tenable Cloud Security Plugin ID 459981

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - **DISPUTED**A failure in the -fstack-protector feature in GCC-based toolchains that target AArch64 allows
 an attacker to exploit an existing buffer overflow in dynamically-sized local variables in your
 application without this being detected. This stack-protector failure only applies to C99-style
 dynamically-sized local variables or those created using alloca(). The stack-protector operates as
 intended for statically-sized local variables. The default behavior when the stack-protector detects an
 overflow is to terminate your application, resulting in controlled loss of availability. An attacker who
 can exploit a buffer overflow without triggering the stack-protector might be able to change program flow
 control to cause an uncontrolled loss of availability or to go further and affect confidentiality or
 integrity. NOTE: The GCC project argues that this is a missed hardening bug and not a vulnerability by
 itself. (CVE-2023-4039)

Solution

Update the gcc-12 library and its related packages to version 12.2.0-14 or later.
