Debian DLA-2313-1 : net-snmp security update

high Nessus Plugin ID 139341

Language:

Synopsis

The remote Debian host is missing a security update.

Description

A privilege escalation vulnerability was discovered in Net-SNMP, a set of tools for collecting and organising information about devices on computer networks, due to incorrect symlink handling (CVE-2020-15861).

This security update also applies an upstream fix to their previous handling of CVE-2020-15862 as part of DLA-2299-1.

For Debian 9 'Stretch', these problems have been fixed in version 5.7.3+dfsg-1.7+deb9u3.

We recommend that you upgrade your net-snmp packages.

For the detailed security status of net-snmp please refer to its security tracker page at:
https://security-tracker.debian.org/tracker/net-snmp

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 packages.
