CVE-2018-1123

Published: 17 May 2018

procps-ng before version 3.3.15 is vulnerable to a denial of service in ps via mmap buffer overflow. Inbuilt protection in ps maps a guard page at the end of the overflowed buffer, ensuring that the impact of this flaw is limited to a crash (temporary denial of service).
