A vulnerability was discovered and corrected in automake: The dist or 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 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 . Packages for 2009.0 are provided as of the Extended Maintenance Program
