Package        : nedit
Problem type   : insecure temporary file
Debian-specific: no

The nedit (Nirvana editor) package as shipped in the non-free section accompanying Debian GNU/Linux 2.2/potato had a bug in its printing code: when printing text it would create a temporary file with the to be printed text and pass that on to the print system. The temporary file was not created safely, which could be exploited by an attacked to make nedit overwrite arbitrary files.

This has been fixed in version 5.02-7.1.

wget url
will fetch the file for you
dpkg -i file.deb
will install the referenced file.

Debian GNU/Linux 2.2 alias potato


Potato was released for alpha, arm, i386, m68k, powerpc and sparc.
