Security Bulletin

This security bulletin contains information about 6 vulnerabilities.

1) Out-of-bounds write

EUVDB-ID: #VU65671

Risk: Medium

CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-24805

CWE-ID: CWE-787 - Out-of-bounds write

Exploit availability: No

Description

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a boundary error when handling INDEX of NET-SNMP-VACM-MIB. A remote attacker can trick the victim into loading a specially crafted MIB collection, trigger an out-of-bounds write and execute arbitrary code on the target system.

Mitigation

Update the affected packages.
net-analyzer/net-snmp to version: 5.9.2

Vulnerable software versions

Gentoo Linux: All versions

net-analyzer/net-snmp: before 5.9.2

CPE2.3 External links

http://security.gentoo.org/glsa/202210-29


Q & A

Can this vulnerability be exploited remotely?

Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the Internet.

Is there known malware, which exploits this vulnerability?

No. We are not aware of malware exploiting this vulnerability.

2) Input validation error

EUVDB-ID: #VU65673

Risk: Low

CVSSv3.1: 3.8 [CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-24806

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

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

The vulnerability exists due to insufficient validation of user-supplied input when SETing malformed OIDs in master agent and subagent simultaneously. A remote user can pass specially crafted input to the application and perform a denial of service (DoS) attack.

Mitigation

Update the affected packages.
net-analyzer/net-snmp to version: 5.9.2

Vulnerable software versions

Gentoo Linux: All versions

net-analyzer/net-snmp: before 5.9.2
