The remote host is missing an update to mozilla announced via advisory DSA 810-1. Several problems have been discovered in Mozilla, the we browser of the Mozilla suite. Since the usual praxis of backporting apparently does not work for this package, this update is basically version 1.7.10 with the version number rolled back, and hence still named 1.7.8. For more details on the problems that have been fixed, please visit the referenced security advisory.

For the stable distribution (sarge) these problems have been fixed in version 1.7.8-1sarge2. For the unstable distribution (sid) these problems have been fixed in version 1.7.10-1. We recommend that you upgrade your Mozilla packages. https://secure1.securityspace.com/smysecure/catid.html?in=DSA%20810-1
