Ubuntu Security Notice USN-484-1
17th July, 2007
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 7.04
- Ubuntu 6.10
- Ubuntu 6.06 LTS
It was discovered that the GnuTLS certificate verification methods
implemented in Curl did not check for expiration and activation dates.
When performing validations, tools using libcurl3-gnutls would
incorrectly allow connections to sites using expired certificates.
The problem can be corrected by updating your system to the following package version:
- Ubuntu 7.04:
- libcurl3-gnutls 7.15.5-1ubuntu2.1
- Ubuntu 6.10:
- libcurl3-gnutls 7.15.4-1ubuntu2.2
- Ubuntu 6.06 LTS:
- libcurl3-gnutls 7.15.1-1ubuntu2.1
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.
