discovered a mishandled error condition in the ASN.1 parser. By
sending specially crafted packet data, a remote attacker could exploit
this to trigger an infinite loop, which would render the service
unusable and consume all available system memory. (CVE-2006-2937)
Certain types of public key could take disproportionate amounts of
time to process. The library now limits the maximum key exponent size
to avoid Denial of Service attacks. (CVE-2006-2940)
Tavis Ormandy and Will Drewry of the Google Security Team discovered a
buffer overflow in the SSL_get_shared_ciphers() function. By sending
specially crafted packets to applications that use this function (like
Exim, MySQL, or the openssl command line tool), a remote attacker
could exploit this to execute arbitrary code with the server's
privileges. (CVE-2006-3738)
Tavis Ormandy and Will Drewry of the Google Security Team reported
that the get_server_hello() function did not sufficiently check the
client's session certificate. This could be exploited to crash clients
by remote attackers sending specially crafted SSL responses.
