NetBSD ftpd and tnftpd are prone to a remote buffer-overflow vulnerability. This issue is due to an off-by-one error; it allows attackers to corrupt memory.
|
|
|
|
Remote attackers may execute arbitrary machine code in the context of the user running the affected application. Failed attempts will likely result in denial-of-service conditions.

|
|
# About
|
|
#
|
|
# tnftpd is a port of the NetBSD FTP server to other systems.
|
|
# It offers many enhancements over the traditional BSD ftpd,
|
|
# including per-class configuration directives via ftpd.conf(5),
|
|
# RFC 2389 and draft-ietf-ftpext-mlst-11 support, IPv6,
|
|
# transfer rate throttling, and more.
|
|
# tnftpd was formerly known as lukemftpd,
|
|
# and earlier versions are present in Mac OS X 10.2 (as ftpd)
|
|
# and FreeBSD 5.0 (as lukemftpd).
|
|
#
|
|
# Description
|
|
#
|
|
# The NetBSD ftpd and the tnftpd port suffer from a remote stack overrun,
|
|
# which can lead to a root compromise.
|
|
#
|
|
# The bug is in glob.c file. The globbing mechanism is flawed as back in
|
|
# 2001.
|
|
#
|
|
# To trigger the overflow you can create a folder and use the globbing
|
|
# special characters (like STARS) to overflow an internal stack based
|
|
buffer.
|
|
#
|
|
# gdb output tested on NetBSD 3.0 i386 NetBSD-ftpd 20050303 :
|
|
# (gdb) c
|
|
# Continuing.
|
|
#
|
|
# Program received signal SIGSEGV, Segmentation fault.
|
|
# 0x00410041 in ?? ()
|
|
# (gdb)
|
|
#
|
|
# tnftpd-20040810 behaves similar.
|
|
# FreeBSD (lukemftpd) and MacOSX (ftpd) were not tested,
|
|
# however they could have the same bug, because of the same
|
|
# codebase.
|
|
#
|
|
# The problem when exploiting this kind of bug is,
|
|
# that we can only control 0x00410041, not the whole
|
|
# 32 bit. However it looks feasible to find a way
|
|
# to do a hole EIP redirection and/or exploit
|
|
# the bug the "unicode" way, which could be especially
|
|
# hard on BSD systems.
