Date Reported:

20 Oct 2001

Affected Packages:

nvi, nvi-m17n

Vulnerable:

Yes

Security database references:

No other external database security references currently available.

More information:

Takeshi Uno found a very stupid format string vulnerability in all versions of nvi (in both, the plain and the multilingualized version). When a filename is saved, it ought to get displayed on the screen. The routine handling this didn't escape format strings.

This problem has been fixed in version 1.79-16a.1 for nvi and 1.79+19991117-2.3 for nvi-m17n for the stable Debian GNU/Linux 2.2.

Even if we don't believe that this could lead into somebody gaining access of another users account if they haven't lost their brain, we recommend that you upgrade your nvi packages.

Fixed in:

Debian GNU/Linux 2.2 (potato)
