Automake is a tool for automatically generating `Makefile.in' files
which is often used in conjuction with Autoconf and other GNU Autotools
to ease portability among applications. It also provides a standardized
and light way of writing complex Makefiles through the use of many
built-in macros.

<description>
<p>
Automake may be vulnerable to a symbolic link attack which may allow an
attacker to modify data or escalate their privileges. This is due to
the insecure way Automake creates directories during compilation. An
attacker may be able to create symbolic links in the place of files
contained in the affected directories, which may potentially lead to
elevated privileges due to modification of data.
