|Gentoo Linux Security Advisory
Title: Opera: Multiple vulnerabilities (GLSA 200710-31)
Date: October 30, 2007
Opera contains multiple vulnerabilities, which may allow the execution of arbitrary code.
Opera is a multi-platform web browser.
Vulnerable: < 9.24
Unaffected: >= 9.24
Architectures: All supported architectures
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).
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.
There is no known workaround at this time for all these vulnerabilities.
All Opera users should upgrade to the latest version:
|# emerge --sync
# emerge --ask --oneshot --verbose ">=www-client/opera-9.24"
