When a new user registers with ICQ, various files are created which are specific to ICQ, including .pnq (ICQ Plugin), .scm (ICQ Sound Scheme), .uin (ICQ User) and .hpf (ICQ Home Page Factory). If a file with any of the mentioned file extensions is accessed, ICQ is the default handler. An issue has been discovered which could cause ICQ to crash. Reportedly, if a user attempts to access a malformed .hpf file ICQ will crash.
