(Oracle Issues Fix for Solaris) OpenSSL DTLS Processing Bugs Let Remote Users Deny Service and Execute Arbitrary Code
SecurityTracker Alert ID:  1030485
SecurityTracker URL:  http://securitytracker.com/id/1030485
CVE Reference:   CVE-2014-0195, CVE-2014-0221   (Links to External Site)
Date:  Jun 27 2014
Impact:   Denial of service via network, Execution of arbitrary code via network, User access via network
Fix Available:  Yes  Vendor Confirmed:  Yes  
Version(s): prior to versions 0.9.8za, 1.0.0m, 1.0.1h
Description:   Two vulnerabilities were reported in OpenSSL. A remote user can execute arbitrary code on the target system. A remote user can cause denial of service conditions.

A remote user can send specially crafted DTLS fragments to the target DTLS client or server to trigger a buffer overflow and execute arbitrary code on the target system [CVE-2014-0195]. Only applications using OpenSSL as a DTLS client or server are affected.

The vendor was notified on April 23, 2014.

Juri Aedla reported this vulnerability (via HP's ZDI).

A remote server can send a specially crafted DTLS handshake to the target DTLS client to trigger a recursion flaw and cause the target service to crash [CVE-2014-0221]. Only applications using OpenSSL as a DTLS client are affected.

The vendor was notified on May 9, 2014.

Imre Rad (Search-Lab Ltd.) reported this vulnerability.

Impact:   A remote user can execute arbitrary code on the target system.

A remote user can cause the target service to crash.
