The remote host is missing an update for the Debian 'procps' package(s) announced via the DLA-1390-1 advisory.
Vulnerability Insight:
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

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

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 Debian 7 Wheezy, these problems have been fixed in version 1:3.3.3.3+deb7u1.
We recommend that you upgrade your procps packages.
