GNU libtool consists of a set of shell scripts used to build shared
libraries.
Joseph S. Myers
and Stefan
Nordhausen independently found a vulnerability in the way
the ltmain.sh script (which is part of the libtool package) creates
temporary directories for its use.
A local attacker could exploit this vulnerability to change/delete
arbitrary files in the system on behalf of the user who is calling the
script. The vulnerability has been fixed in the 1.5.2 version of libtool.
