net-snmp vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 22.04 LTS
- Ubuntu 20.04 LTS
- Ubuntu 18.04 LTS

Summary:

Several security issues were fixed in Net-SNMP.

Software Description:
- net-snmp: SNMP (Simple Network Management Protocol) server and applications

Details:

Yu Zhang and Nanyu Zhong discovered that Net-SNMP incorrectly handled
memory operations when processing certain requests. A remote attacker could
use this issue to cause Net-SNMP to crash, resulting in a denial of
service, or possibly execute arbitrary code.
