CVE-2010-2478: Integer Overflow
First published: Tue Jun 29 2010(Updated: )
Description of problem: On a 32-bit machine, info.rule_cnt >= 0x40000000 leads to integer overflow and the buffer may be smaller than needed. Since ETHTOOL_GRXCLSRLALL is unprivileged, this can presumably be used for at least denial of service.
