CVE ID         : CVE-2018-1122 CVE-2018-1123 CVE-2018-1124 CVE-2018-1125

Debian Bug     : 899170

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.
