描述

Automake is a tool for automatically generating Makefile.in files compliant
with the GNU Coding Standards.

It was found that the distcheck rule in Automake-generated Makefiles made a
directory world-writable when preparing source archives. If a malicious,
local user could access this directory, they could execute arbitrary code
with the privileges of the user running "make distcheck". (CVE-2012-3386)

Red Hat would like to thank Jim Meyering for reporting this issue. Upstream
acknowledges Stefano Lattarini as the original reporter.

All automake users are advised to upgrade to this updated package, which
contains a backported patch to correct this issue.
