CVE-2006-2940

TITLE

OpenSSL SSLv2 client code fails to properly check for NULL

DESCRIPTION

OpenSSL 0.9.7 before 0.9.7l, 0.9.8 before 0.9.8d, and earlier versions allows attackers to cause a denial of service (CPU consumption) via parasitic public keys with large (1) "public exponent" or (2) "public modulus" values in X.509 certificates that require extra time to process when using RSA signature verification. A flaw in the OpenSSL library could allow a remote attacker to cause a denial of service on an affected application. Multiple RSA implementations fail to properly handle RSA signatures. This vulnerability may allow an attacker to forge RSA signatures. OpenSSL is prone to a denial-of-service vulnerability because it fails to validate the lengths of public keys being used. rPath Security Advisory: 2006-0175-2 Published: 2006-09-28 Updated: 2006-09-29 Resolved issue in patch for CVE-2006-2940 Products: rPath Linux 1 Rating: Major Exposure Level Classification: Remote Deterministic Unauthorized Access Updated Versions: openssl=/conary.rpath.com@rpl:devel//1/0.9.7f-10.5-1 openssl-scripts=/conary.rpath.com@rpl:devel//1/0.9.7f-10.5-1 References: http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-2937 http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-2940 http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-3738 http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-4343 http://issues.rpath.com/browse/RPL-613 Description: Previous versions of the openssl package are vulnerable to multiple attacks. In particular, any connection that the mysql daemon will accept may be vulnerable. In the default configuration of mysql, that would be a local unauthorized access vulnerability, but mysql can be configured to listen for network connections from remote hosts, which would then enable remote unauthorized access. Any program that calls the SSL_get_shared_ciphers() function may be vulnerable. 29 September 2006 Update: The initial fix for this vulnerability was incomplete, and the fault in the fix could enable a Denial of Service attack in some cases of the attack described in CVE-2006-2940. _______________________________________________ Full-Disclosure - We believe in it.
