CVE-2014-4502
Multiple heap-based buffer overflows in the parse_notify function in sgminer before 4.2.2, cgminer before 4.3.5, and BFGMiner before 4.1.0 allow remote pool servers to have unspecified impact via a (1) large or (2) negative value in the Extranonc2_size…
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (3.30%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
