Last modified

CVE-2002-1420 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 0.33% chance of exploitation in the next 30 days.
