Security Bulletin

This security bulletin contains information about 2 vulnerabilities.

1) Input validation error

EUVDB-ID: #VU41292

Risk: Medium

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:Green]

CVE-ID: CVE-2014-6421

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

The vulnerability allows remote attackers to perform a denial of service (DoS) attack.

The vulnerability exists due to insufficient validation of user-supplied input. A remote attacker can cause a denial of service (application crash) via a crafted packet that leverages split memory ownership between the SDP and RTP dissectors.

Mitigation

Install update from vendor's website.

Vulnerable software versions

Wireshark: 1.10.0 - 1.10.9

2) Buffer overflow

EUVDB-ID: #VU41293

Risk: Medium

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:Green]

CVE-ID: CVE-2014-6422

CWE-ID: CWE-119 - Memory corruption

Exploit availability: No

Description

The vulnerability allows a remote non-authenticated attacker to perform service disruption.

The SDP dissector in Wireshark 1.10.x before 1.10.10 creates duplicate hashtables for a media channel, which allows remote attackers to cause a denial of service (application crash) via a crafted packet to the RTP dissector.

Mitigation

Install update from vendor's website.
