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.
