CVE-2020-24175
Buffer overflow in Yz1 0.30 and 0.32, as used in IZArc 4.4, ZipGenius 6.3.2.3116, and Explzh (extension) 8.14, allows attackers to execute arbitrary code via a crafted archive file, related to filename handling.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.76%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
