openssl (0.9.7e-3sarge3) stable-security; urgency=high

  * Non-maintainer upload by the Security Team
  * Apply patch to fix infinite loop / memory allocation denial of
    service due to mis-handling of error conditions on invalid ASN1
    data.  CVE-2006-2937
  * Apply patch to fix a buffer overflow in the SSL_get_shared_ciphers
    function.  CVE-2006-3738
  * Apply patch to fix a denial of service in the SSLv2 client code
    whereby a malicious server could cause a client to crash.
    CVE-2006-4343
  * Apply patch to correct a potential denial of service attack when
    parsing ASN1 data from untrusted sources.  Certain types of public
    key can take a disproportionate amount of time to process, allowing
    an attacker to exhaust system resources.  CVE-2006-2940
