A vulnerability was discovered and corrected in automake:

The (1) dist or (2) distcheck rules in GNU Automake 1.11.1, 1.10.3,
and release branches branch-1-4 through branch-1-9, when producing a
distribution tarball for a package that uses Automake, assign insecure
permissions (777) to directories in the build tree, which introduces
a race condition that allows local users to modify the contents of
package files, introduce Trojan horse programs, or conduct other
attacks before the build is complete (CVE-2009-4029).

Packages for 2009.0 are provided as of the Extended Maintenance
Program. Please visit this link to learn more:
