"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 Debian 7 'Wheezy', these problems have been fixed in version
1:3.3.3-3+deb7u1.

We recommend that you upgrade your procps packages.

The Debian LTS team would like to thank Abhijith PA for preparing this
update.

introducing additional issues."
