Vulnerability identifier: #VU68895
Vulnerability risk: High
Exploitation vector: Network
Exploit availability: Yes
Vendor: OpenSSL Software Foundation
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when processing the email address field inside X.509 certificate. A remote attacker can supply a specially crafted certificate to the application, trigger a 4-byte buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system but requires that either a CA signs the malicious certificate or for the application to continue certificate verification despite failure to construct a path to a trusted issuer.
