IBM Lotus Notes HTML RTF conversion buffer overflow

notes-html-rtf-bo (37363) The risk level is classified as HighHigh Risk

Description:

IBM Lotus Notes is vulnerable to a buffer overflow when HTML messages are converted to RTF (Rich Text Format). By sending a specially-crafted HTML email to a vulnerable system, a remote attacker could overflow a buffer and execute arbitrary code on the system or cause the victim's email client to crash, once the message is converted back to an HTML message after initially being converted to RTF. This conversion occurs when the message is forwarded, replied to with history, or copied to the clipboard.
