- Steven van Acker reported on bugtraq that the version of cfingerd (a
- configurable finger daemon) as distributed in Debian GNU/Linux 2.2
- suffers from two problems:
-
-
- The code that reads configuration files (files in which $ commands are
- expanded) copied its input to a buffer without checking for a buffer
- overflow. When the ALLOW_LINE_PARSING feature is enabled that code
- is used for reading users\' files as well, so local users could exploit
- this.
-
- There also was a printf call in the same routine that did not protect
- against printf format attacks.
-
-
- Since ALLOW_LINE_PARSING is enabled in the default /etc/cfingerd.conf
- local users could use this to gain root access.
-
- This has been fixed in version 1.4.1-1.2, and we recommend that you upgrade
- your cfingerd package immediately.

- Solution : http://www.debian.org/security/2001/dsa-066
- Risk factor : High';
