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.

Multiple buffer overflows in the ISO network protocol support in the NetBSD kernel 2.0 through 4.0BETA2, and NetBSD-current before 20070329, allow local users to execute arbitrary code via long parameters to certain functions, as demonstrated by a long sockaddr structure argument to the clnproute function.

The display driver allocattr functions in NetBSD 3.0 through 4.0BETA2, and NetBSD-current before 20070728, allow local users to cause a denial of service (panic) via a (1) negative or (2) large value in an ioctl call, as demonstrated by the vgaallocattr function.
