=========================================================== 
Ubuntu Security Notice USN-353-1         September 28, 2006
openssl vulnerabilities
CVE-2006-2937, CVE-2006-2940, CVE-2006-3738, CVE-2006-4343
===========================================================

A security issue affects the following Ubuntu releases:

Ubuntu 5.04
Ubuntu 5.10
Ubuntu 6.06 LTS

This advisory also applies to the corresponding versions of
Kubuntu, Edubuntu, and Xubuntu.

The problem can be corrected by upgrading your system to the
following package versions:

Ubuntu 5.04:
  libssl0.9.7                              0.9.7e-3ubuntu0.4

Ubuntu 5.10:
  libssl0.9.7                              0.9.7g-1ubuntu1.3

Ubuntu 6.06 LTS:
  libssl0.9.8                              0.9.8a-7ubuntu0.2

After a standard system upgrade you need to reboot your computer to
effect the necessary changes.

Details follow:

Dr. Henson of the OpenSSL core team and Open Network Security
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.
(CVE-2006-4343)
