CVE-2010-2434
Buffer overflow in Arcext.dll 2.16.1 and earlier in pon software Explzh 5.62 and earlier allows remote attackers to execute arbitrary code via an LZH LHA file with a crafted header that is not properly handled during expansion.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (5.36%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
