Ubuntu Security Notice USN-353-2
4th October, 2006
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 6.06 LTS
- Ubuntu 5.10
- Ubuntu 5.04
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)
The problem can be corrected by updating your system to the following package version:
- Ubuntu 6.06 LTS:
- 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
To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
After a standard system upgrade you need to reboot your computer to
effect the necessary changes.
