Advisory 2006-09-15.01

Norton Insufficient validation of 'SymEvent' driver input buffer

Basic information:


Release date: September 15, 2006

Last update: April 1, 2007

Severity:Medium

Character:System crash

Status:Unknown

Testing program: BTP00011P002NF.zip

Description:

Norton insufficiently protects its driver '\Device\SymEvent' against a manipulation by malicious applications and it fails to validate its input buffer. It is possible to open this driver and send arbitrary data to it, which are implicitly believed to be valid. It is possible to assemble the data in the input buffer such that the driver performs an invalid memory operation and crashes the whole operating system. Further impacts of this bug were not examined.
