View on CVE.org

Published Sep 1, 2004 CVSS 2.0 · 7.2 High EPSS < 1% KEV · Not listed

Description

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.
