USN-5543-1: Net-SNMP vulnerabilities
1 August 2022
Several security issues were fixed in Net-SNMP.
Releases
Packages
- 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.
