Multiple Mozilla products BOM characters security bypass

firefox-bom-security-bypass (45356) The risk level is classified as MediumMedium Risk

Description:

Multiple Mozilla products, including Firefox, Thunderbird and SeaMonkey could allow a remote attacker to bypass security restrictions. Certain BOM characters are stripped from JavaScript code prior to execution. By persuading a victim to visit a Web site containing specially-crafted control format Unicode characters, an attacker could exploit this vulnerability to bypass script filters and perform cross-site scripting attacks.
