KDE kdenetwork lan:// URL handler buffer overflow

kde-kdenetwork-lan-bo (10598) The risk level is classified as HighHigh Risk

Description:

The LISa LAN (Local Area Network) browsing tool included in the kdenetwork package in the K Desktop Environment (KDE) is vulnerable to a buffer overflow in the lan:// URL handler, which is used to access LISa. By creating a specially-crafted lan:// URL request and sending it to a victim within an HTML email or Web page, a remote attacker could overflow a buffer and gain access to the victim's account, once the link is clicked.
