Multiple vulnerabilities have been discovered in Opera, allowing for file disclosure, privilege escalation and Cross-Site scripting.
|Package||www-client/opera on all architectures|
|Affected versions||< 9.26|
|Unaffected versions||>= 9.26|
Opera is a fast web browser that is available free of charge.
Mozilla discovered that Opera does not handle input to file form fields properly, allowing scripts to manipulate the file path (CVE-2008-1080). Max Leonov found out that image comments might be treated as scripts, and run within the wrong security context (CVE-2008-1081). Arnaud reported that a wrong representation of DOM attribute values of imported XML documents allows them to bypass sanitization filters (CVE-2008-1082).
A remote attacker could entice a user to upload a file with a known path by entering text into a specially crafted form, to execute scripts outside intended security boundaries and conduct Cross-Site Scripting attacks.
There is no known workaround at this time.
All Opera users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=www-client/opera-9.26"
