CVE-ID: CVE-2023-4039
CWE-ID:
CWE-254 - Security Features
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to bypass implemented security restrictions.
The vulnerability exists due to the GCC's stack smashing protection does not detect or defend against overflows of dynamically-sized local variables on AArch64 targets. A remote attacker can bypass expected security restrictions and successfully exploit buffer overflow vulnerabilities.
Update the affected package gcc13 to the latest version.
Vulnerable software versionsSUSE Linux Enterprise Micro: 5.3 - 5.5
