Due to incorrect accounting when decoding and escaping Unicode data in procfs, ps is vulnerable to overflowing an mmap()ed region when formatting the process list for display. Since ps maps a guard page at the end of the buffer, impact is limited to a crash.(CVE-2018-1123)

If an argument longer than INT_MAX bytes is given to pgrep, 'int bytes' could wrap around back to a large positive int (rather than approaching zero), leading to a stack buffer overflow via strncat().(CVE-2018-1125)
