Security Bulletin

This security bulletin contains information about 3 vulnerabilities.

1) Out-of-bounds read

EUVDB-ID: #VU12882

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-2017-14160

CWE-ID: CWE-125 - Out-of-bounds read

Exploit availability: No

Description

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

The weakness exists in the bark_noise_hybridmp function in psy.c due to out-of-bounds read. A remote attacker can trick the victim into opening a specially crafted mp4 file and cause the service to crash.

Mitigation

Update the affected packages.
media-libs/libvorbis to version: 1.3.6-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) Memory corruption

EUVDB-ID: #VU13263

Risk: Low

CVSSv4.0: 2.7 [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:U/U:Clear]

CVE-ID: CVE-2018-10392

CWE-ID: CWE-119 - Memory corruption

Exploit availability: No

Description

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

The vulnerability exists due to improper validation of the number of channels by mapping0_forward in mapping0.c in Xiph.Org libvorbis. A remote unauthenticated attacker can send a specially crafted file, trigger heap-based buffer overflow or over-read and cause the service to crash.

Mitigation

Update the affected packages.
