Mandrake Linux Security Advisory : wu-ftpd (MDKSA-2003:080)

Critical Nessus Plugin ID 61921


The remote Mandrake Linux host is missing a security update.


A vulnerability was discovered by Janusz Niewiadomski and Wojciech Purczynski in the wu-ftpd FTP server package. They found an off-by- one bug in the fb_realpath() function which could be used by a remote attacker to obtain root privileges on the server. This bug can only be successfully accomplished by using wu-ftpd binaries compiled on Linux 2.0.x and later 2.4.x kernels because the 2.2.x and earlier 2.4.x kernels define PATH_MAX to be 4095 characters.

wu-ftpd is no longer shipped with Mandrake Linux, however Mandrake Linux 8.2 did come with wu-ftpd. If you use wu-ftpd, you are encouraged to upgrade to these patched packages.


Update the affected wu-ftpd package.
