Security Bulletin

This security bulletin contains information about 2 vulnerabilities.

1) NULL pointer dereference

EUVDB-ID: #VU70878

Risk: Medium

CVSSv3.1: 5.9 [CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H/E:P/RL:O/RC:C]

CVE-ID: CVE-2022-44792

CWE-ID: CWE-476 - NULL Pointer Dereference

Exploit availability: Yes

Description

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a NULL pointer dereference error within the handle_ipDefaultTTL() function in agent/mibgroup/ip-mib/ip_scalars.c. A remote non-authenticated attacker can send specially crafted UDP to the application and perform a denial of service (DoS) attack.

Mitigation

Update the affected package net-snmp to the latest version.
