Netwosix Linux Security Advisory #2004-0010 <>
- -----------------------------------------------------------------------------------

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.

- - -> 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.
