Description
This security bulletin contains information about 4 secuirty vulnerabilities.
1) Buffer overflow (CVE-ID: CVE-2014-0195)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.The vulnerability exists due to a boundary error in OpenSSL when processing DTLS fragments to an OpenSSL DTLS client or server. A remote attacker can send a specially crafted request to vulnerable application and cause the server to crash or execute arbitrary code on the target system.
Successful exploitation of the vulnerability requires that server support DTLS.
2) Resource management error (CVE-ID: CVE-2014-0221)
The vulnerability allows a remote attacker to perform a denial of service attack.The vulnerability exists due to an error when processing invalid DTLS handshake. A remote attacker can initiate SSL/TLS connection to the affected application and trigger denial of service conditions.
3) Man-in-the-Middle attack (CVE-ID: CVE-2014-0224)
The vulnerability allows a remote attacker to decrypt encrypted connections.The vulnerability exists due to an error in OpenSSL. A remote attacker with ability to intercept network traffic can decrypt SSL connection and gain access to sensitive data.
4) Resource management error (CVE-ID: CVE-2014-3470)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.The vulnerability exists due to an error when processing ECDH ciphersuites in TLS clients. A remote attacker can send a specially crafted response to vulnerable OpenSSL client and cause the application to crash.
