Description

This security bulletin contains information about 4 vulnerabilities.


1) SRTP Memory Leak (CVE-ID: CVE-2014-3513)

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

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Green


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.

2) Information disclosure (CVE-ID: CVE-2014-3566)

CWE-ID: CWE-327 - Use of a Broken or Risky Cryptographic Algorithm

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


The vulnerability allows a remote attacker to perform MitM attack.

The vulnerability exists due to usage of insecure SSLv3 protocol in OpenSSL. A remote attacker can force the current connection between user and server to be downgraded to SSLv3 protocol and then use padding-oracle attack on Cypher-block chaining (CBC) mode to decrypt encrypted communication.

Successful exploitation of the vulnerability may allow an attacker to read encrypted communications in clear text.

Note: The vulnerability is known as POODLE.

3) Session Ticket Memory Leak (CVE-ID: CVE-2014-3567)

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

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


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.

4) Forced SSLv3 support (CVE-ID: CVE-2014-3568)

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

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear


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.
