    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.
    
    For the oldstable distribution (jessie), these problems have been fixed
    in version 2:3.3.9-9+deb8u1.
    
    For the stable distribution (stretch), these problems have been fixed in
    version 2:3.3.12-3+deb9u1.
    
    We recommend that you upgrade your procps packages.
    
    For the detailed security status of procps please refer to its security
    tracker page at: https://security-tracker.debian.org/tracker/procps
