Detail

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-3ubuntu0.6

Ubuntu 5.10:
libssl0.9.7 0.9.7g-1ubuntu1.5

Ubuntu 6.06 LTS:
libssl0.9.8 0.9.8a-7ubuntu0.3

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

Details follow:

USN-353-1 fixed several vulnerabilities in OpenSSL. However, Mark J Cox noticed that the applied patch for CVE-2006-2940 was flawed. This update corrects that patch.

For reference, this is the relevant part of the original advisory:

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)
