Integer Signedness Error in select() Allows Arbitrary Kernel Memory Overwrite

CVE-2002-1420 · HIGH Severity

AV:L/AC:L/AU:N/C:C/I:C/A:C

Integer signedness error in select() on OpenBSD 3.1 and earlier allows local users to overwrite arbitrary kernel memory via a negative value for the size parameter, which satisfies the boundary check as a signed integer, but is later used as an unsigned integer during a data copying operation.
