"The Qualys Research Labs discovered multiple vulnerabilities in
procps, a set of command line and full screen utilities for browsing
procfs. The Common Vulnerabilities and Exposures project identifies
the following problems :

  - CVE-2018-1122
    top read its configuration from the current working
    directory if no $HOME was configured. If top were
    started from a directory writable by the attacker (such
    as /tmp) this could result in local privilege
    escalation.

  - CVE-2018-1123
    Denial of service against the ps invocation of another
    user.

  - CVE-2018-1124
    An integer overflow in the file2strvec() function of
    libprocps could result in local privilege escalation.

  - CVE-2018-1125
    A stack-based buffer overflow in pgrep could result in
    denial of service for a user using pgrep for inspecting
    a specially crafted process.

  - CVE-2018-1126
    Incorrect integer size parameters used in wrappers for
    standard C allocators could cause integer truncation and
    lead to integer overflow issues."
