[USN-884-1] OpenSSL vulnerability

By | 2010/01/13

===========================================================
Ubuntu Security Notice USN-884-1           January 14, 2010
openssl vulnerability
CVE-2009-4355
===========================================================

It was discovered that OpenSSL did not correctly free unused memory in certain situations.  A remote attacker could trigger this flaw in services that used SSL, causing the service to use all available system memory, leading to a denial of service.

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

Ubuntu 6.06 LTS:
libssl0.9.8                     0.9.8a-7ubuntu0.11

Ubuntu 8.04 LTS:
libssl0.9.8                     0.9.8g-4ubuntu3.9

Ubuntu 8.10:
libssl0.9.8                     0.9.8g-10.1ubuntu2.6

Ubuntu 9.04:
libssl0.9.8                     0.9.8g-15ubuntu3.4

Ubuntu 9.10:
libssl0.9.8                     0.9.8g-16ubuntu3.1

After a standard system upgrade you need to restart any applications using OpenSSL, especially Apache, to effect the necessary changes.
