Debian Security Advisory DSA-055-1 security@debian.org
http://www.debian.org/security/ Wichert Akkerman
May 8, 2001
- - ------------------------------------------------------------------------
Package : gftp
Problem type : printf format attack
Debian-specific: no
The gftp package as distributed with Debian GNU/Linux 2.2 has a problem
in its logging code: it logged data received from the network but it did
not protect itself from printf format attacks. An attacker can use this
by making a FTP server return special responses that exploit this.
This has been fixed in version 2.0.6a-3.1, and we recommend that you
upgrade your gftp package.
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.
