CVE-2006-4781

Estado: ModificadaAlta (7.5)—

Heap-based buffer overflow in FutureSoft TFTP Server Multithreaded (MT) 1.1 allows remote attackers to cause a denial of service (crash) or possibly execute arbitrary code by sending a crafted packet to port 69/UDP, which triggers the overflow when constructing an absolute path name. NOTE: Some details are obtained from third party information.
