Overview:

The OpenSSL has published a security update addressing the two high-risk buffer overflow vulnerabilities. The flaws exist in the validation process of X.509 certificates of OpenSSL. Successful exploitation of these vulnerabilities allows an attacker to cause a denial of service condition or execute the remote code. We strongly recommend applying the security update for these vulnerabilities on high priority.
