2007: The year of the 9,999 vulnerabilities?

A look at the National Vulnerability Database statistics will reveal that the number of vulnerabilities found yearly has greatly increased since 2003:


Average yearly increase (including the 2002-2003 decline): 48%

6605*1.48= 9775

So, that’s not quite 9999, but fairly close.  There’s enough variance that hitting 9999 in 2007 seems a plausible event.  If not in 2007, then it seems likely that we’ll hit 9999 in 2008.  So, what does it matter?

MITRE’s CVE effort uses a numbering scheme for vulnerabilities that can accomodate only 9999 vulnerabilities:  CVE-YEAR-XXXX.  Many products and vulnerability databases that are CVE-compatible (e.g., my own Cassandra service, CIRDB, etc…) use a field of fixed size just big enough for that format.  We’re facing a problem similar, although much smaller in scope, to the year-2000 overflow.  When the board of editors of the CVE was formed, the total number of vulnerabilities known, not those found yearly, was in the hundreds.  A yearly number of 9999 seemed astronomical;  I’m sure that anyone who would have brought up that as a concern back then would have been laughed at.  I felt at the time that it would take a security apocalypse to reach that.  Yet there we are, and a fair warning to everyone using or developing CVE-compatible products.

Kudos to the National Vulnerability Database and the MITRE CVE teams for keeping up under the onslaught.  I’m impressed.

Elisa’s dead

No, not our esteemed director of research.  It turned off my ELISA project, Enterprise-Level Information Security Assurance, due to lack of interest from the public at large.  The idea for this web application was to keep track of patches and basically support NIST’s recommendation on managing patches to use such a system.  I believe this indicates that the process was too heavy;  people don’t like to spend so much effort and money managing patches.
