Mozilla, Firefox, Thunderbird, and Netscape non-ascii character buffer overflow
| mozilla-netscape-nonascii-bo (17378) |  High Risk |
Description:
Mozilla is vulnerable to a heap overflow, caused by improper handling of non-ascii characters in a URL. By creating a specially-crafted URL request containing non-ascii characters, a remote attacker could overflow a buffer and execute arbitrary code on the system, once the link is clicked. An attacker could exploit this vulnerability by hosting the malicious URL on a Web site or by sending it to a victim as an HTML email.
