CVE-2008-5331
Adobe Acrobat 9 uses more efficient encryption than previous versions, which makes it easier for attackers to guess a document's password via a brute-force attack.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.00%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
