DESCRIPTION:
Francis Provencher has discovered a vulnerability in Observer, which
can be exploited by malicious people to cause a DoS (Denial of
Service).

The vulnerability is caused due to a NULL-pointer dereference error
when copying an octet string from a variable binding list. This can
be exploited to cause a crash via a specially crafted SNMP SetRequest
PDU sent to UDP port 162.

The vulnerability is confirmed in version 15.1 Build 0007.0000. Other
versions may also be affected.

SOLUTION:
Restrict access to trusted hosts only.

PROVIDED AND/OR DISCOVERED BY:
