Mandrake Linux Security Update Advisory
________________________________________________________________________
Package name: wu-ftpd
Advisory ID: MDKSA-2003:080
Date: July 31st, 2003
Affected versions: 8.2
________________________________________________________________________
Problem Description:
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.
