Security Bulletin

This security bulletin contains information about 6 vulnerabilities.

1) NULL pointer dereference

EUVDB-ID: #VU35701

Risk: Medium

CVSSv4.0: 4.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2019-13959

CWE-ID: CWE-476 - NULL Pointer Dereference

Exploit availability: No

Description

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

In Bento4 1.5.1-627, AP4_DataBuffer::SetDataSize does not handle reallocation failures, leading to a memory copy into a NULL pointer. This is different from CVE-2018-20186.

Mitigation

Install update from vendor's website.

2) Input validation error

EUVDB-ID: #VU36167

Risk: Medium

CVSSv4.0: 4.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2019-7697

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

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

An issue was discovered in Bento4 v1.5.1-627. There is an assertion failure in AP4_AtomListWriter::Action in Core/Ap4Atom.cpp, leading to a denial of service (program crash), as demonstrated by mp42hls.

Mitigation

Install update from vendor's website.

3) Resource exhaustion

EUVDB-ID: #VU36168

Risk: Medium

CVSSv4.0: 4.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2019-7698

CWE-ID: CWE-400 - Resource exhaustion

Exploit availability: No

Description

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

An issue was discovered in AP4_Array<AP4_CttsTableEntry>::EnsureCapacity in Core/Ap4Array.h in Bento4 1.5.1-627. Crafted MP4 input triggers an attempt at excessive memory allocation, as demonstrated by mp42hls, a related issue to CVE-2018-20095.

Mitigation

Install update from vendor's website.

4) Buffer overflow

EUVDB-ID: #VU36169

Risk: Medium

CVSSv4.0: 4.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2019-7699

CWE-ID: CWE-119 - Memory corruption

Exploit availability: No

Description

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

A heap-based buffer over-read occurs in AP4_BitStream::WriteBytes in Codecs/Ap4BitStream.cpp in Bento4 v1.5.1-627. Remote attackers could leverage this vulnerability to cause an exception via crafted mp4 input, which leads to a denial of service.

Mitigation

Install update from vendor's website.
