Security Bulletin

This security bulletin contains information about 2 vulnerabilities.

1) Denial of service

EUVDB-ID: #VU10565

Risk: Low

CVSSv4.0: 6.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2017-16820

CWE-ID: CWE-415 - Double Free

Exploit availability: No

Description

The vulnerability allows a remote unauthenticated attacker to cause DoS condition on the target system.

The weakness exists due to the csnmp_read_table function in the snmp.c code in the SNMP plug-in of the collectd daemon. A remote attacker can send specially crafted input to the target system, trigger a double-free memory condition and cause the collected daemon to crash.

Mitigation

Update the affected packages.
app-admin/collectd to version: 5.7.2-r1

Vulnerable software versions

Gentoo Linux: All versions

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: #VU37389

Risk: Low

CVSSv4.0: 4.3 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2017-18240

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

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

The Gentoo app-admin/collectd package before 5.7.2-r1 sets the ownership of PID file directory to the collectd account, which might allow local users to kill arbitrary processes by leveraging access to this account for PID file modification before a root script sends a SIGKILL (when the service is stopped).

Mitigation

Update the affected packages.
app-admin/collectd to version: 5.7.2-r1

Vulnerable software versions

Gentoo Linux: All versions

Q & A

Can this vulnerability be exploited remotely?

No. This vulnerability can be exploited locally. The attacker should have authentication credentials and successfully authenticate on the system.

Is there known malware, which exploits this vulnerability?

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