The x86-64 kernel system-call functionality in Xen 4.1.2 and earlier, as used in Citrix XenServer 6.0.2 and earlier and other products; Oracle Solaris 11 and earlier; illumos before r13724; Joyent SmartOS before 20120614T184600Z; FreeBSD before 9.0-RELEASE-p3; NetBSD 6.0 Beta and earlier; Microsoft Windows Server 2008 R2 and R2 SP1 and Windows 7 Gold and SP1; and possibly other operating systems, when running on an Intel processor, incorrectly uses the sysret path in cases where a certain address is not a canonical address, which allows local users to gain privileges via a crafted application. NOTE: because this issue is due to incorrect use of the Intel specification, it should have been split into separate identifiers; however, there was some value in preserving the original mapping of the multi-codebase coordinated-disclosure effort to a single identifier.

Multiple integer signedness errors in smb_subr.c in the netsmb module in the kernel in NetBSD 5.0.2 and earlier, FreeBSD, and Apple Mac OS X allow local users to cause a denial of service (panic) via a negative size value in a /dev/nsmb ioctl operation, as demonstrated by a (1) SMBIOC_LOOKUP or (2) SMBIOC_OPENSESSION ioctl call.

The kernel in NetBSD, probably 5.0.1 and earlier, on x86 platforms does not properly handle a pre-commit failure of the iret instruction, which might allow local users to gain privileges via vectors related to a tempEIP pseudocode variable that is outside of the code-segment limits.

libprop/prop_object.c in proplib in NetBSD 4.0 and 4.0.1 allows local users to cause a denial of service (NULL pointer dereference and kernel panic) via a malformed externalized plist (XML form) containing an undefined element.

The pam_unix module in OpenPAM in NetBSD 4.0 before 4.0.2 and 5.0 before 5.0.1 allows local users to change the current root password if it is already known, even when they are not in the wheel group.

The TCP implementation in (1) Linux, (2) platforms based on BSD Unix, (3) Microsoft Windows, (4) Cisco products, and probably other operating systems allows remote attackers to cause a denial of service (connection queue exhaustion) via multiple vectors that manipulate information in the TCP state table, as demonstrated by sockstress.
