Details

Dirk Mueller discovered that UTF8 strings could be made to cause a small
buffer overflow. A remote attacker could exploit this by sending specially
crafted strings to applications that use the Qt3 library for UTF8 processing,
potentially leading to arbitrary code execution with user privileges, or a
denial of service.
