+
+Raphael Geissert have found that this package contains a script that
+can be abused by an attacker to execute arbitrary code.
+
+The vulnerability is introduced by an insecure change to
+LD_LIBRARY_PATH, and environment variable used by ld.so(8) to look for
+libraries on a directory other than the standard paths.
+
+Vulnerable code follows:
+
+/usr/bin/tauex line 197:
+export LD_LIBRARY_PATH=$TAUROOT/$TAUARCH/lib/$theBinding:$LD_LIBRARY_PATH
+
+When there's an empty item on the colon-separated list of
+LD_LIBRARY_PATH, ld.so treats it as '.' (i.e. CWD/$PWD.)
+If the given script is executed from a directory where a potential,
+local, attacker can write files to, there's a chance to exploit this
+bug.
