Several unauthorised SSL certificates have been found in the wild issued for the DigiNotar Certificate Authority, obtained through a security compromise with said company. Debian, like other software distributors, has as a precaution decided to disable the DigiNotar Root CA by default in the NSS crypto libraries. As a result from further understanding of the incident, this update to DSA 2300 disables additional DigiNotar issuing certificates. For the lenny-backports distribution the problems have been fixed in version 3.12.8-1+squeeze3~bpo50+1. For the squeeze-backports distribution the problems have been fixed in version 3.12.11-3~bpo60+1. For the oldstable distribution (lenny), this problem has been fixed in version 3.12.3.1-0lenny6. For the stable distribution (squeeze), this problem has been fixed in version 3.12.8-1+squeeze3. For the unstable distribution (sid), this problem has been fixed in version 3.12.11-3. We recommend that you upgrade your nss packages. Upgrade instructions -------------------- If you don't use pinning (see [1]) you have to update the package manually via "apt-get -t lenny-backports install <packagelist>" with the packagelist of your installed packages affected by this update. [1] <http://backports.debian.org/Instructions> We recommend to pin (in /etc/apt/preferences) the backports repository to 200 so that new versions of installed backports will be installed automatically. Package: * Pin: release a=lenny-backports Pin-Priority: 200
