Disclosure Date


A remote overflow exists in linux-ftpd-ssl. The SSL code fails to validate input to the vsprintf() function resulting in a stack-based buffer overflow. With a specially crafted request which generates more than 2048 bytes of response from the server, a remote attacker can cause arbitrary code execution resulting in a loss of integrity.


Location: Remote / Network Access
Attack Type: Input Manipulation
Impact: Loss of Integrity

Currently, there are no known workarounds or upgrades to correct this issue. However, James Longstreet has released an unofficial patch to address this vulnerability.
