CVE-2019-16736
A stack-based buffer overflow in processCommandUploadSnapshot in libcommon.so in Petwant PF-103 firmware 4.22.2.42 and Petalk AI 3.2.2.30 allows remote attackers to cause denial of service or run arbitrary code as the root user.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (3.39%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
