source: http://www.securityfocus.com/bid/22145/info Transmit 3 is prone to a heap-overflow vulnerability because it fails to perform sufficient boundary checks on user-supplied data before copying it to a buffer. An attacker could leverage this issue to have arbitrary code execute with administrative privileges. A successful exploit could result in the complete compromise of the affected system. Transmit 3 version 3.5.5 and prior are reported vulnerable.
