CVE-2010-4531

17
FAUCET Score

CVE-2010-4531 describes a stack-based buffer overflow in the ATRDecodeAtr function within the PCSC-Lite smart card daemon (pcscd), affecting versions 1.5.3 and potentially other 1.5.x and 1.6.x releases. This vulnerability allows physically proximate attackers to trigger a denial of service or potentially execute arbitrary code by presenting a specially crafted smart card with an overly long Answer-to-Reset (ATR) message. Rated with a CVSS score of 4.4, its exploitation requires physical access and moderate attack complexity, leading to potential confidentiality, integrity, and availability impacts. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage surrounding this CVE.
