Description Jan Lieskovsky 2010-12-21 14:45:46 EST
Three stack-based buffer overflow flaws were found in the way
OpenSC device drivers for A-Trust ACOS, ACS ACOS5 and 
STARCOS SPK 2.3 based smart cards processed certain
values of card serial number. A local attacker could use this
flaw to execute arbitrary code, with the privileges of the
user running the opesc-tool or opensc-explorer binaries via
a malicious smart card, with specially-crafted value of its
serial number, inserted to the system.
