[原文]NetBSD 2.0 before 20050316 and NetBSD-current before 20050112 allow local users to cause a denial of service (infinite loop and system hang) by calling the F_CLOSEM fcntl with a parameter value of 0.
NetBSD contains a flaw that may allow a local denial of service. The issue is triggered when a malicious user calls F_CLOSEM fnctl() with the parameter 0, causing an infinite loop in the kernel, resulting in a loss of availability for the platform.
Upgrade to version 2.0 after the correction date or higher, as it has been reported to fix this vulnerability. An upgrade is required as there are no known workarounds.
