CVE-2005-3007: Opera before 8.50 allows remote attackers to spoof the content type of files via a filename with a trailing...

Security readout for executives and security teams

Opera versions before 8.50 could misrepresent a file’s content type when the filename ended with a dot. That could help an attacker make dangerous content look safer and persuade a user to open or process it. The record does not show active exploitation or a CVSS score. Exposure is most plausible in legacy environments still using Opera before 8.50, especially where Opera handles email attachments, downloads, or untrusted files. Modern standard browser deployments are unlikely to be exposed unless old Opera installations remain unmanaged. Treat this as a legacy software hygiene issue unless affected Opera versions are still present. The business urgency rises if old Opera is used for email or file handling. Prioritize inventory and removal over emergency response because active exploitation is not evidenced in the supplied sources. Mitigation focus: Identify and remove Opera versions earlier than 8.50.; Upgrade affected systems to Opera 8.50 or later where still required.; Prevent legacy Opera from handling email attachments or downloaded files..
