CCID is a generic USB Chip/Smart Card Interface Devices driver.
CCID contains an integer overflow vulnerability in ccid_serial.c.
A physically proximate attacker could execute arbitrary code via a smart card with a specially crafted serial number.
There is no known workaround at this time.
All CCID users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=app-crypt/ccid-1.4.1-r1"
NOTE: This is a legacy GLSA. Updates for all affected architectures are available since January 21, 2011. It is likely that your system is already no longer affected by this issue.
