===========================================================
Ubuntu Security Notice USN-49-1		  December 23, 2004
debmake vulnerability
CAN-2004-1179
===========================================================

A security issue affects the following Ubuntu releases:

Ubuntu 4.10 (Warty Warthog)

The following packages are affected:

debmake

The problem can be corrected by upgrading the affected package to
version 3.7.4ubuntu0.1.  In general, a standard system upgrade is
sufficient to effect the necessary changes.

Details follow:

Javier Fernández-Sanguino Peña noticed that the debstd script from
debmake, a deprecated helper package for Debian packaging, created
temporary directories in an insecure manner. This could allow a
symlink attack to create or overwrite arbitrary files with the
privileges of the user invoking the program.
