CVE-2011-1512
Heap-based buffer overflow in xlssr.dll in Autonomy KeyView, as used in IBM Lotus Notes before 8.5.2 FP3, allows remote attackers to execute arbitrary code via a malformed BIFF record in a .xls Excel spreadsheet attachment, aka SPR PRAD8E3HKR.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (6.87%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
