Detail

Synopsis

Opera contains multiple vulnerabilities, which may allow the execution of arbitrary code.

Background

Opera is a multi-platform web browser.

Description

Michael A. Puls II discovered an unspecified flaw when launching external email or newsgroup clients (CVE-2007-5541). David Bloom discovered that when displaying frames from different websites, the same-origin policy is not correctly enforced (CVE-2007-5540).

Impact

An attacker could potentially exploit the first vulnerability to execute arbitrary code with the privileges of the user running Opera by enticing a user to visit a specially crafted URL. Note that this vulnerability requires an external e-mail or newsgroup client configured in Opera to be exploitable. The second vulnerability allows an attacker to execute arbitrary script code in a user's browser session in context of other sites or the theft of browser credentials.

Workaround

There is no known workaround at this time for all these vulnerabilities.

Resolution

All Opera users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=www-client/opera-9.24"
