"Google security engineer Ryan Sleevi found a vulnerability in the
NetScape Portable Runtime Library (NSPR). NSPR allocated memory
without specific checks, making it possible for remote attackers to
cause a Denial of Service or execute arbitrary code.

For Debian 6 'Squeeze', this issue have been fixed in nspr version
4.8.6-1+squeeze3. We recommend that you upgrade your nspr packages.
