Security Bulletin

This security bulletin contains information about 3 vulnerabilities.

1) Integer overflow

EUVDB-ID: #VU83856

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-2021-28429

CWE-ID: CWE-190 - Integer overflow

Exploit availability: No

Description

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

The vulnerability exists due to integer overflow within the av_timecode_make_string in libavutil/timecode.c. A local user can pass specially crafted data to the application, trigger integer overflow and cause a denial of service condition on the target system.

Mitigation

Install updates from vendor's repository.

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.

2) NULL pointer dereference

EUVDB-ID: #VU71645

Risk: Low

CVSSv4.0: 1.2 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2022-3341

CWE-ID: CWE-476 - NULL Pointer Dereference

Exploit availability: No

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 decode_main_header() function in libavformat/nutdec.c A remote attacker can trick the victim to open a specially crafted file and perform a denial of service (DoS) attack.

Mitigation

Install updates from vendor's repository.

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.

3) Buffer overflow

EUVDB-ID: #VU1048

Risk: High

CVSSv4.0: 6.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber]

CVE-ID: CVE-2016-6432

CWE-ID: CWE-120 - Buffer overflow

Exploit availability: No

Description

The vulnerability allows a remote unauthenticated user to execute arbitrary code on the target system.
The weakness is caused by improper checking of the input. By returning a specially crafted NetBIOS packet via IPv4 in response to a NetBIOS probe sent by the target system, attackers can trigger a buffer overflow that lets execute arbitrary code.
Successful exploitation of the vulnerability results in arbitrary code execution on the vulnerable system.

Mitigation

Install updates from vendor's repository.
