Impact:
Denial of service via network, Execution of arbitrary code via network, User access via network
|
Fix Available: Yes Vendor Confirmed: Yes

Description:
Several vulnerabilities were reported in OpenSSL. A remote user can cause denial of service conditions. A remote user can execute arbitrary code on the target system. HP System Management Homepage for Linux and Windows is affected.
A remote user can send specially crafted, invalid ASN.1 structures to trigger an infinite loop [CVE-2006-2937]. As a result, the process will consume excessive system memory. Versions prior to 0.9.7 are not affected.
A remote user can use certain types of public keys to cause the target system to take a disproportionate amount of time to process [CVE-2006-2940].
Dr. S. N. Henson developed the ASN.1 test suite for NISCC that uncovered these denial of service vulnerabilities.
A user can send a specially crafted list of ciphers to an application that uses the SSL_get_shared_ciphers() function to trigger a buffer overflow and potentially execute arbitrary code [CVE-2006-3738]. The vendor credits Tavis Ormandy and Will Drewry of the Google Security Team with reporting this vulnerability.
A remote server can cause a connected SSLv2 client to crash [CVE-2006-4343]. The vendor credits Tavis Ormandy and Will Drewry of the Google Security Team with reporting this vulnerability.
