OpenSSL RFC 3779 denial of service

openssl-rfc3779-dos (72131) The risk level is classified as MediumMedium Risk

Description:

OpenSSL is vulnerable to a denial of service, caused by the improper handling of malicious RFC 3779 data in certificates. If OpenSSL is configured with "enable-rfc3779", a remote attacker could exploit this vulnerability to cause an assertion error.

*CVSS:

Base Score: 4.3
  Access Vector: Network
  Access Complexity: Medium
  Authentication: None
  Confidentiality Impact: None
  Integrity Impact: None
  Availability Impact: Partial
 
Temporal Score: 3.2
  Exploitability: Unproven
  Remediation Level: Official-Fix
  Report Confidence: Confirmed

Consequences:

Denial of Service

Remedy:

Upgrade to the latest version of OpenSSL (0.9.8s or 1.0.0f or later), available from the OpenSSL Web site. See References.

Refer to the appropriate IBM Security Bulletin for patch, upgrade or suggested workaround information. See References.
