Descriptions
The TCP reassembly function in the inet module in FreeBSD 8.3 before p16, 8.4 before p9, 9.1 before p12, 9.2 before p5, and 10.0 before p2 allows remote attackers to cause a denial of service (undefined memory access and system crash) or possibly read system memory via multiple crafted packets, related to moving a reassemble queue entry to the segment list when the queue is full.
La función de reensamblaje de TCP en el módulo inet en FreeBSD 8.3 anterior a p16, 8.4 anterior a p9, 9.1 anterior a p12, 9.2 anterior a p5 y 10.0 anterior a p2 permite a atacantes remotos causar una denegación de servicio (acceso a memoria no definido y caída de sistema) o posiblemente leer memoria de sistema a través de múltiples paquetes manipulados, relacionado con trasladar una entrada de cola de reensamblaje hacia la lista de segmento cuando la cola está llena.
FreeBSD may add a reassemble queue entry on the stack into the segment list when the reassembly queue reaches its limit. The memory from the stack is undefined after the function returns. Subsequent iterations of the reassembly function will attempt to access this entry. An attacker who can send a series of specifically crafted packets with a connection could cause a denial of service situation by causing the kernel to crash. Additionally, because the undefined on stack memory may be overwritten by other kernel threads, while extremely difficult, it may be possible for an attacker to construct a carefully crafted attack to obtain portion of kernel memory via a connected socket. This may result in the disclosure of sensitive information such as login credentials, etc. before or even without crashing the system.
