OVERVIEW:

	CA's previous software update failed to properly fix one of the 
	serious remote vulnerabilities reported in AL-2006.0094 for 
	Brightstor ARCserve Backup and CA Protection Suites. Systems with 
	the original update applied are still vulnerable.

	CA have now released new software updates which must be applied in 
	addition to the updates released with the original bulletin.


IMPACT:

	A remote, unauthenticated attacker can potentially take complete 
	control of the vulnerable systems, executing arbitrary code with
	SYSTEM privileges.


MITIGATION:

	It is necessary to apply both the original fix [2] and the new 
	updated fix [3].
