CVE-2017-11323
Stack-based buffer overflow in ESTsoft ALZip 8.51 and earlier allows remote attackers to execute arbitrary code via a crafted MS-DOS device file, as demonstrated by use of "AUX" as the initial substring of a filename.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.95%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
