LJ2410.jpgHewlett-Packard has warned owners of some of its laser printers to update their devices' firmware or risk having remote attackers access previously-printed documents.  According to Digital Defense, the security company that reported the problem to HP last October, attackers can exploit a bug in the printers' Web-based control interface to "read arbitrary system configuration files, cached documents, etc."  Affected printers include:

HP LaserJet 2410 with firmware prior to 20080819 SPCL112A
HP LaserJet 2420 with firmware prior to 20080819 SPCL112A
HP LaserJet 2430 with firmware prior to 20080819 SPCL112A
