Debian DLA-1390-1 : procps security update

critical Nessus Plugin ID 110312
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote Debian host is missing a security update.

Description

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.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected libprocps0, libprocps0-dev, and procps packages.
