Summary
OpenSSL is prone to multiple denial of service (DoS) vulnerabilities.
Insight
Insight
The following vulnerabilities exist: - An integer overflow could allow remote attackers to cause a denial of service (crash) via an SSL client certificate with certain ASN.1 tag values. - Incorrect tracking of the number of characters in certain ASN.1 inputs could allow remote attackers to cause a denial of service (crash) by sending an SSL client certificate that causes OpenSSL to read past the end of a buffer when the long form is used.
Affected Software
Affected Software
OpenSSL version 0.9.6 through 0.9.6j and 0.9.7 through 0.9.7b.
Detection Method
