Security Bulletin

This security bulletin contains one medium risk vulnerability.

1) Security features bypass

EUVDB-ID: #VU81045

Risk: Medium

CVSSv3.1: 4.9 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:L/E:U/RL:O/RC:C]

CVE-ID: CVE-2023-4039

CWE-ID: CWE-254 - Security Features

Exploit availability: No

Description

The 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.

Mitigation

Update the affected package gcc12 to the latest version.
