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.
