Version Summary:VMware has re-released a security advisory and updated software to address the OpenSSL OCSP invalid key denial of service vulnerability.
 
 
Description
OpenSSL contains a vulnerability that could an unauthenticated, remote attacker to cause a denial of service (DoS) condition.

The vulnerability is due to improper handling of Online Certificate Status Protocol (OCSP) response verification messages. An unauthenticated, remote attacker could exploit the vulnerability by transmitting a crafted certificate response with an invalid key. Successful exploitation could allow an attacker to cause a DoS condition on the targeted system.

OpenSSL has confirmed the vulnerability and released software updates.
 
Warning Indicators
The following OpenSSL versions are vulnerable:
  • 1.0.1c and prior
  • 1.0.0j and prior
  • 0.9.8x and prior
 
IntelliShield Analysis
To exploit the vulnerability, the attacker may need access to trusted or internal networks to send crafted messages to the targeted system. This access requirement could limit the likelihood of a successful exploit.

VMware has re-released a security advisory at the following link: VMSA-2013-0009
 
Impact
An unauthenticated, remote attacker could exploit the vulnerability to cause the affected software to stop responding. This could result in a DoS condition for applications that use the affected software for secure transmission services.
 
Technical Information
The vulnerability is due to insufficient checks for NULL keys implemented in the OpenSSL source code files crypto/ocsp/ocsp_vfy.c and crypto/asn1/a_verify.c when handling OCSP signatures.

An unauthenticated, remote attacker could exploit the vulnerability by hosting a malicious OCSP server and responding to OCSP verifications with a crafted OCSP certificate response that contains a NULL key. When the malicious response is processed by the affected software, the software could terminate abnormally, denying service to legitimate users. Successful exploitation could allow an attacker to cause a DoS condition on the targeted system.
 
Safeguards
Administrators are advised to apply the appropriate updates.

Administrators may consider using an alternate product.

Administrators may consider using IP-based access control lists (ACLs) to allow only trusted systems to access the affected systems.
