Description

The SSL/TLS handshaking code in OpenSSL does not properly check the length of Kerberos tickets during an SSL/TLS handshake when using Kerberos ciphersuites. This allows remote attackers to cause a denial of service by manipulating the parameters during SSL/TLS handshake, causing an out-of-bounds read and crashing OpenSSL.

Classification

Location: Local Access Required, Remote / Network Access
Attack Type: Denial of Service, Input Manipulation
Impact: Loss of Availability
Exploit: Exploit Public

Solution

Upgrade to version 0.9.7d or higher, as it has been reported to fix this vulnerability. An upgrade is required as there are no known workarounds.

Products

OpenSSL Project	OpenSSL	0.9.7a
		0.9.7b
