Synopsis: Older versions of NEdit make insecure use of temp files
Software: nedit
History:
2001-04-27 Update available in Progeny archive
Affects: Progeny Debian (nedit prior to 5.1.1-1.0progeny1)
Progeny Only: NO
Vendor-Status: New Version Released
5.1.1-1.0progeny1
$Id: PROGENY-SA-2001-10,v 1.1 2001/04/27 15:09:05 jdaily Exp $
---------------------------------------------------------------------------
DESCRIPTION
NEdit, a popular GUI editor, insecurely opens a file in /tmp for
printing purposes. This vulnerability could be used by a local
attacker to cause a privileged user to unwittingly overwrite a file
(via a symbolic link) to which the user has write access.
SOLUTION (See also: UPDATING VIA APT-GET)
If you have NEdit installed, upgrade to a fixed version of nedit.
nedit version 5.1.1-1.0progeny1 corrects the problem. For your
convenience, you may upgrade to the new package.
If you aren't sure if you have NEdit installed, type:
dpkg -l nedit
...at a command prompt. If you don't have it installed, you can
disregard this warning.
UPDATING VIA APT-GET
1. Ensure that your /etc/apt/sources.list file has a URI for Progeny's
update repository:
deb http://archive.progeny.com/progeny updates/newton/
2. Update your cache of available packages for apt(8).
Example:
# apt-get update
3. Using apt(8), install the new package. apt(8) will download the
update, verify its integrity with md5, and then install the
package on your system with dpkg(8).
Example:
# apt-get install nedit
UPDATING VIA DPKG
1. Using your preferred FTP/HTTP client to retrieve the following
updated files from Progeny's update archive at:
http://archive.progeny.com/progeny/updates/newton/
MD5 Checksum Filename
-------------------------------- -------------------------------------
142a511170fbf30ce2881d362787658a nedit_5.1.1-1.0progeny1_i386.deb
Example:
# wget \
http://archive.progeny.com/progeny/updates/newton/nedit_5.1.1-1.0progeny1_i386.deb
2. Use the md5sum command on the retrieved files to verify that they
match the md5sum provided in this advisory:
Example:
# md5sum nedit_5.1.1-1.0progeny1_i386.deb
3. Then install the replacement package(s) using the dpkg command.
Example:
# dpkg --install nedit_5.1.1-1.0progeny1_i386.deb
WORKAROUND
Other than removing the nedit software, no known workaround exists for
this vulnerability.
