Title: Transmit 3 Remote Heap Overflow Vulnerability
Severity: CRITICAL
Description:
Transmit 3 is an FTP application designed for use on the Mac OS X operating system.
Transmit 3 is prone to a heap-overflow vulnerability because the server fails to perform sufficient boundary checks on user-supplied data before copying it into an insufficiently sized buffer. Specifically, the application fails to allocate enough space when dealing with strings passed on by the URL handler.
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.
Affected Products:
- Transmit 3 Transmit 3 3.5.5
