Synopsis

The remote EulerOS host is missing multiple security updates.

Description

According to the versions of the net-snmp packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

 - handle_ipDefaultTTL in agent/mibgroup/ip-mib/ip_scalars.c in Net-SNMP 5.8 through 5.9.3 has a NULL Pointer Exception bug that can be used by a remote attacker (who has write access) to cause the instance to crash via a crafted UDP packet, resulting in Denial of Service. (CVE-2022-44792)

 - handle_ipv6IpForwarding in agent/mibgroup/ip-mib/ip_scalars.c in Net-SNMP 5.4.3 through 5.9.3 has a NULL Pointer Exception bug that can be used by a remote attacker to cause the instance to crash via a crafted UDP packet, resulting in Denial of Service. (CVE-2022-44793)
