Debian DSA-4154-1 : net-snmp - security update

critical Nessus Plugin ID 108696

Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

A heap corruption vulnerability was discovered in net-snmp, a suite of Simple Network Management Protocol applications, triggered when parsing the PDU prior to the authentication process. A remote, unauthenticated attacker can take advantage of this flaw to crash the snmpd process (causing a denial of service) or, potentially, execute arbitrary code with the privileges of the user running snmpd.

Solution

Upgrade the net-snmp packages.

For the oldstable distribution (jessie), these problems have been fixed in version 5.7.2.1+dfsg-1+deb8u1.

For the stable distribution (stretch), these problems have been fixed before the initial release.
