Apr 08, 2004, 21:59 (0 Talkback[s])
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.

Location:

  You can download the latest version of this package in NEPOTE format from:   <http://download.netwosix.org/0009/nepote>

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.

Netwosix Linux Security Advisory #2004-0010 <http://www.netwosix.org>


Package name: util-linux
Summary: leak problem in util-linux
Date: 2004-04-08
Affected versions: Netwosix 1.0 Netwosix 1.1

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.

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.
