Description
+ A security issue has been found in procps-ng <= 3.3.14 where an attacker can overflow the output buffer of ps, when executed by another user, administrator, or script: a denial of service only (not an LPE), because ps mmap()s its output buffer and mprotect()s its last page with PROT_NONE (an effective guard page).
