FTP: ProFTPD (Linux PPC) User Command Vulnerability (1)
This signature detects attempts to exploit a known vulnerability against ProFTPD. Versions 1.2pre6 and earlier are vulnerable. Attackers can send a malicious format string to overflow the PWD command.
Extended Description
The vulnerability in 1.2pre1, 1.2pre3 and 1.2pre3 is a remotely exploitable buffer overflow, the result of a sprintf() in the log_xfer() routine in src/log.c. The vulnerability in 1.2pre4 is a mkdir overflow. The name of the created path can not exceed 255 chars. 1.2pre6 limits the command buffer size to 512 characters in src/main.c and modifies the fix from 1.2pre4.
