Opera: Multiple vulnerabilities

Background

Opera is a multi-platform web browser.

Description

Opera contains several vulnerabilities:

• fails to properly validate Content-Type and filename.
• fails to properly validate date: URIs.
• uses kfmclient exec as the Default Application to handle downloaded files when integrated with KDE.
• fails to properly control frames.
• uses Sun Java packages insecurely.
• searches an insecure path for plugins.

Impact

An attacker could exploit these vulnerabilities to:

• execute arbitrary code.
• load a malicious frame in the context of another browser session.
• leak information.

Workaround

There is no known workaround at this time.

Resolution

All Opera users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=www-client/opera-7.54-r3"
