Description
Automake-generated Makefiles made certain directories world-writable when
preparing source archives, as was recommended by the GNU Coding Standards.
If a malicious, local user could access the directory where a victim was
creating distribution archives, they could use this flaw to modify the
files being added to those archives. Makefiles generated by these updated
automake packages no longer make distribution directories world-writable,
as recommended by the updated GNU Coding Standards. (CVE-2009-4029)
