Mandrake Linux Security Advisory : wu-ftpd (MDKSA-2000:014)

high Nessus Plugin ID 61812

Language:

Synopsis

The remote Mandrake Linux host is missing a security update.

Description

Wu-ftpd is vulnerable to a very serious remote attack in the SITE EXEC implementation. Because of user input going directly into a format string for a *printf function, it is possible to overwrite important data, such as a return address, on the stack. When this is accomplished, the function can jump into shellcode pointed to by the overwritten eip and execute arbitrary commands as root. While exploited in a manner similar to a buffer overflow, it is actually an input validation problem. Anonymous ftp is exploitable making it even more serious as attacks can come anonymously from anywhere on the internet.

This update also fixes the setproctitle() vulnerability which involves a missing character-formatting argument in setproctitle(), a call which sets the string used to display process identifier information.

Solution

Update the affected wu-ftpd package.
