OpenSSL vulnerability

Releases

Details

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)

Update instructions

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

Ubuntu 6.06
  • libssl0.9.8 - 0.9.8a-7ubuntu0.3
Ubuntu 5.10
  • libssl0.9.7 - 0.9.7g-1ubuntu1.5
Ubuntu 5.04
  • libssl0.9.7 - 0.9.7e-3ubuntu0.6

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