var-200403-0072
Vulnerability from variot
FreeBSD 5.1 and earlier, and Mac OS X before 10.3.4, allows remote attackers to cause a denial of service (resource exhaustion of memory buffers and system crash) via a large number of out-of-sequence TCP packets, which prevents the operating system from creating new connections. FreeBSD fails to limit the number of TCP segments held in a reassembly queue which could allow an attacker to exhaust all available memory buffers (mbufs) on the destination system resulting in a denial-of-service condition. FreeBSD of FreeBSD Unspecified vulnerabilities exist in products from multiple vendors.None. A problem in the handling of out-of-sequence packets has been identified in BSD variants such as FreeBSD and OpenBSD. Because of this, it may be possible for remote attackers to deny service to legitimate users of vulnerable systems
