CONECTIVA LINUX SECURITY ANNOUNCEMENT
- --------------------------------------------------------------------------

PACKAGE : licq
SUMMARY : Remote command execution
DATE : 2001-03-27 14:16:00
ID : CLA-2001:389
RELEVANT
RELEASES : 4.0, 4.0es, 4.1, 4.2, 5.0, prg graficos, ecommerce, 5.1, 6.0

- -------------------------------------------------------------------------

DESCRIPTION
"licq" is a very popular ICQ graphical client.
Previous versions have two vulnerabilities that could be exploited by
a remote attacker to execute arbitrary commands on the client host.
The first vulnerability is a buffer overflow in a log function.
The second vulnerability consists in the use of the system() function
to invoke an external browser when an URL is received. This function
will expand and interpret shell characters and this could be used to
execute commands on behalf of the user running licq.

SOLUTION
It is recommended that all licq users install the update for their
specific version of the distribution.

ADDITIONAL INSTRUCTIONS
Users of Conectiva Linux version 6.0 or higher may use apt to perform
upgrades of RPM packages:
- add the following line to /etc/apt/sources.list if it is not there yet
(you may also use linuxconf to do this):

rpm [cncbr] ftp://atualizacoes.conectiva.com.br 6.0/conectiva updates

(replace 6.0 with the correct version number if you are not running CL6.0)

- run: apt-get update
- after that, execute: apt-get upgrade
