CVE-2023-42465 : What You Need to Know
Discover the security impact of CVE-2023-42465, a vulnerability in Sudo before 1.9.15 that could lead to authentication bypass or privilege escalation. Learn about affected systems, exploitation, and mitigation steps.
Sudo before 1.9.15 might allow row hammer attacks (for authentication bypass or privilege escalation) because application logic sometimes is based on not equaling an error value (instead of equaling a success value), and because the values do not resist flips of a single bit.
