Security Bulletin

This security bulletin contains information about 5 vulnerabilities.

1) Buffer overflow

EUVDB-ID: #VU12361

Risk: Medium

CVSSv4.0: 4 [CVSS:4.0/AV:L/AC:L/AT:P/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2018-10538

CWE-ID: CWE-190 - Integer overflow

Exploit availability: No

Description

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to boundary error within ParseRiffHeaderConfig function in riff.c when processing WAV files. A remote unauthenticated attacker can create a specially crafted WAV file, trick the victim into opening it and trigger integer overflow in bytes_to_copy calculation and subsequent malloc call

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

Mitigation

Install patch from vendor's website:
https://github.com/dbry/WavPack/commit/6f8bb34c2993a48ab9afbe353e6d0cff7c8d821d

Vulnerable software versions

WavPack: 4.1 - 5.1.0

CPE2.3

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) Buffer overflow

EUVDB-ID: #VU12362

Risk: Medium

CVSSv4.0: 4 [CVSS:4.0/AV:L/AC:L/AT:P/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2018-10539

CWE-ID: CWE-190 - Integer overflow

Exploit availability: No

Description

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to boundary error within ParseDsdiffHeaderConfig function in dsdiff.c when processing WAV files. A remote unauthenticated attacker can create a specially crafted WAV file, trick the victim into opening it and trigger integer overflow in bytes_to_copy calculation and subsequent malloc call

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

3) Buffer overflow

EUVDB-ID: #VU12363

Risk: Medium

CVSSv4.0: 4 [CVSS:4.0/AV:L/AC:L/AT:P/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2018-10540

CWE-ID: CWE-190 - Integer overflow

Exploit availability: No

Description

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to boundary error within ParseWave64HeaderConfig function in wave64.c when processing WAV files. A remote unauthenticated attacker can create a specially crafted WAV file, trick the victim into opening it and trigger integer overflow in bytes_to_copy calculation and subsequent malloc call

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

4) Heap-based buffer overwrite

EUVDB-ID: #VU12398

Risk: Medium

CVSSv4.0: 4.5 [CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P/U:Green]

CVE-ID: CVE-2018-10536

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

Exploit availability: No

Description

The vulnerability allows a local attacker to cause DoS condition or execute arbitrary code on the target system.

The weakness exists in the WAV parser component due to improper rejection of multiple format chunks by the ParseRiffHeaderConfig function, as defined in the riff.c source code file. A local attacker can execute a specially crafted .wav file, trigger heap buffer overwrite and cause the service to crash or execute arbitrary code.

Successful exploitation of the vulnerability may result in system compromise.

Mitigation

Install update from vendor's website.
