    CVE-2018-1124

    Published: 23 May 2018Last Modified: 8 Jul 2026

    Summary:

    Details: procps-ng before version 3.3.15 is vulnerable to multiple integer overflows leading to a heap corruption in file2strvec function. This allows a privilege escalation for a local attacker who can create entries in procfs by starting processes, which could result in crashes or arbitrary code execution in proc utilities run by other users.
