CVE-2010-4523
Multiple stack-based buffer overflows in libopensc in OpenSC 0.11.13 and earlier allow physically proximate attackers to execute arbitrary code via a long serial-number field on a smart card, related to (1) card-acos5.c, (2) card-atrust-acos.c, and (3)…
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.86%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
