CONECTIVA LINUX SECURITY ANNOUNCEMENT
- --------------------------------------------------------------------------
PACKAGE : libtool
SUMMARY : Insecure handling of temporary files
DATE : 2004-02-05 18:11:00
ID : CLA-2004:811
RELEVANT
RELEASES : 8, 9

DESCRIPTION
GNU libtool consists of a set of shell scripts used to build shared
libraries.
Joseph S. Myers and Stefan Nordhausen independently found[1,2] a
vulnerability[3] 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.
This update keeps the original versions distributed with Conectiva
Linux, fixing the vulnerability by using mktemp to securely create
the directories.
SOLUTION
All developers using libtool should upgrade.
