Synopsis ========
Opera fails to correctly verify certain signatures.
Background ==========
Opera is a multi-platform web browser.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 www-client/opera < 9.0.2 >= 9.0.2
Description ===========
Opera makes use of OpenSSL, which fails to correctly verify PKCS #1 v1.5 RSA signatures signed by a key with exponent 3. Some CAs in Opera's list of trusted signers are using root certificates with exponent 3.
Impact ======
An attacker could forge certificates which will appear valid and signed by a trusted CA.
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-9.0.2"
