Multiple vulnerabilities in IBM FlashSystem 840 and V840 systems

1) SRTP Memory Leak

EUVDB-ID: #VU5212

Risk: Medium

CVSSv3.1: 6.3 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:N/A:L/E:U/RL:O/RC:C]

CVE-ID: CVE-2014-3513

CWE-ID: CWE-401 - Missing release of memory after effective lifetime

Exploit availability: No

Description

The vulnerability allows a remote attacker to obtain potentially sensitive information and cause denial of service.

The vulnerability exists due to a parsing error within DTLS SRTP extension in OpenSSL. A remote attacker can send a carefully crafted handshake message and free up to 64k of memory or cause denial of service conditions.

Successful exploitation of the vulnerability may allow an attacker to obtain potentially sensitive data, stored in system memory, or cause the affected service to fail.

Mitigation

Install update from vendor's website.

Vulnerable software versions

2) Session Ticket Memory Leak

EUVDB-ID: #VU5213

Risk: Medium

CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2014-3567

CWE-ID: CWE-401 - Missing release of memory after effective lifetime

Exploit availability: No

Description

The vulnerability allows a remote attacker to cause denial of service.

The vulnerability exists due to an error when handling integrity of session tickets in OpenSSL. A remote attacker can send a large number of invalid session tickets and cause denial of service conditions.

Successful exploitation of the vulnerability may allow an attacker to perform a denial of service (DoS) attack.

Mitigation

Install update from vendor's website.

3) Forced SSLv3 support

EUVDB-ID: #VU5215

Risk: Low

CVSSv3.1: 5.2 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2014-3568

CWE-ID: CWE-749 - Exposed Dangerous Method or Function

Exploit availability: No

Description

The vulnerability allows a remote attacker to force SSLv3 usage.

When OpenSSL is configured with "no-ssl3" as a build option, servers could accept and complete a SSL 3.0 handshake, and clients could be configured to send them. A remote attacker can force SSLv3 usage and perfom a variety of attacks against SSLv3 protocol

Successful exploitation of the vulnerability may allow an attacker to obtain potentially sensitive information.

Mitigation

Install update from vendor's website.
