[Jamie Strandboge]

==========================================================================
Ubuntu Security Notice USN-1428-1
April 24, 2012

openssl vulnerability
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 11.10
- Ubuntu 11.04
- Ubuntu 10.04 LTS
- Ubuntu 8.04 LTS

Summary:

An application using OpenSSL could be made to crash or run programs if it
opened a specially crafted file.

Software Description:
- openssl: Secure Socket Layer (SSL) cryptographic library and tools

Details:

It was discovered that the fix for CVE-2012-2110 was incomplete for OpenSSL
0.9.8. A remote attacker could trigger this flaw in services that used SSL
to cause a denial of service or possibly execute arbitrary code with
application privileges. Ubuntu 11.10 was not affected by this issue.
(CVE-2012-2131)

The original upstream fix for CVE-2012-2110 would cause BUF_MEM_grow_clean()
to sometimes return the wrong error condition. This update fixes the
problem.

Update instructions:

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

Ubuntu 11.10:
  libssl1.0.0                     1.0.0e-2ubuntu4.5

Ubuntu 11.04:
  libssl0.9.8                     0.9.8o-5ubuntu1.5

Ubuntu 10.04 LTS:
  libssl0.9.8                     0.9.8k-7ubuntu8.11

Ubuntu 8.04 LTS:
  libssl0.9.8                     0.9.8g-4ubuntu3.18

After a standard system update you need to reboot your computer to make
all the necessary changes.
