Security Bulletin

This security bulletin contains information about 2 vulnerabilities.

1) Null pointer dereference

EUVDB-ID: #VU15678

Risk: Low

CVSSv4.0: 5.5 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:P/U:Clear]

CVE-ID: CVE-2018-13440

CWE-ID: CWE-476 - NULL Pointer Dereference

Exploit availability: No

Description

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

The vulnerability exists in the ModuleState::setup function, as defined in the modules/ModuleState.cpp source code file due to a NULL pointer exception bug. A remote attacker can send a malicious CAF file, trigger a NULL pointer dereference condition and cause the affected application to crash.

Mitigation

Install updates from vendor's website.

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. However, proof of concept for this vulnerability is available.

2) Heap-based buffer overflow

EUVDB-ID: #VU15679

Risk: High

CVSSv4.0: 7 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P/U:Amber]

CVE-ID: CVE-2018-17095

CWE-ID: CWE-122 - Heap-based Buffer Overflow

Exploit availability: No

Description

The vulnerability allows a local attacker to gain elevated privileges on the target system.

The vulnerability exists in the ModuleState::setup function due to a heap-based buffer overflow condition that occurs when running sfconvert. A remote attacker can trick the victim into opening or executing a specially crafted file that submits malicious input, trigger memory corruption and cause the service to crash or execute arbitrary code with elevated privileges.

Successful exploitation of the vulnerability may result in system compromise.

Mitigation

Install updates from vendor's website.
