Vulnerability in Openbsd

CVE-2002-1420

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: 0.003 (25.5th percentile) — read the EPSS interpretation.
