mICQ 0.4.9 and earlier allows remote attackers to cause a denial of service (crash) via malformed ICQ message types without a 0xFE separator character. We will provide erratum packages containing mICQ version 0.4.10.2 which is not vulnerable to this issue. This will be RHSA-2003:119, CAN-2002-1362
Erratum was released in April http://rhn.redhat.com/errata/RHSA-2003-119.html
