Netwosix Linux Security Advisory #2004-0009 <http://www.netwosix.org>
Package name: automake
Summary: Automake symbolic link
vulnerability
Date:
2004-04-08
Affected versions: Netwosix 1.0
Netwosix 1.1
Package description:
Automake is a tool for automatically generating `Makefile.in’
files compliant with the GNU Coding Standards. Automake requires
the use of GNU Autoconf.
Problem description:
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.
Action:
We recommend that all systems with this package installed be
upgraded. Please note that if you do not need the
functionality provided by this package, you may want to
remove it from your system.

About Linux Netwosix:
Linux Netwosix is a powerful and optimized Linux distribution for servers and Network Security related jobs. It can also be used for special operations such as penetration testing with its big collection of security oriented software and sources. It's a light distribution created for the requirements of every SysAdmin and it's very portable and highly configurable. Our philosophy is to give greater liberty for configuration to the SysAdmin. Only in this way can he/she configure a powerful and stable server machine. Linux Netwosix also has a powerful ports system (Nepote) similar to the xBSD systems but more flexible and usable.

Package description:
Util-linux is a suite of essential utilities for any Linux system. Its primary audience is system integrators and DIY Linux hackers. Util-linux is attempting to be portable, but the only platform it has been tested much on is Linux i386. It contains the following programs: agetty arch blockdev cal cfdisk chfn chkdupexe chsh clear col colcrt colrm column ctrlaltdel cytune ddate dmesg elvtune fastboot fasthalt fdformat fdisk fsck.cramfs fsck.minix getopt halt hexdump hwclock initctl ipcrm ipcs isosize kill last line logger login look mcookie mesg mkfs mkfs.bfs mkfs.cramfs mkfs.minix mkswap more mount namei need passwd pg pivot_root ramsize raw rdev readprofile reboot rename renice rescuept reset rev rootflags script setfdprm setsid setterm sfdisk shutdown simpleinit sln swapoff swapon tunelp ul umount vidmode vipw wall whereis write.
Problem description:
The login program in util-linux 2.11 and earlier uses a pointer after it has been freed and reallocated, which could cause login to leak sensitive data.
