Navision Financials Server 2.60 and earlier allows remote attackers to cause a denial of service by sending a null character and a long string to the server port (2407), which causes the server to crash.

Navision Financials Server 2.0 allows remote attackers to cause a denial of service via a series of connections to the server without providing a username/password combination, which consumes the license limits.

A certain pseudo-random number generator (PRNG) algorithm that uses XOR and 2-bit random hops (aka "Algorithm X2"), as used in OpenBSD 2.6 through 3.4, Mac OS X 10 through 10.5.1, FreeBSD 4.4 through 7.0, and DragonFlyBSD 1.0 through 1.10.1, allows remote attackers to guess sensitive values such as IP fragmentation IDs by observing a sequence of previously generated values. NOTE: this issue can be leveraged for attacks such as injection into TCP packets and OS fingerprinting.
