CVE-2005-4779

Status: ModifiedLow (3.6)—

verifiedexecioctl in verified_exec.c in NetBSD 2.0.2 calls NDINIT with UIO_USERSPACE rather than UID_SYSSPACE, which removes the functionality of the verified exec kernel subsystem and might allow local users to execute Trojan horse programs.

CVSS

Version: 2.0
Vector: AV:L/AC:L/Au:N/C:P/I:P/A:N
