Opera is a fast Web browser that is available free of charge.
David Bloom reported two vulnerabilities where plug-ins (CVE-2007-6520)
and Rich text editing (CVE-2007-6522) could be used to allow cross
domain scripting. Alexander Klink (Cynops GmbH) discovered an issue
with TLS certificates (CVE-2007-6521). Gynvael Coldwind reported that
bitmaps might reveal random data from memory (CVE-2007-6524).
<impact type="normal">
A remote attacker could exploit these vulnerabilities, possibly leading
to the execution of arbitrary code and cross domain scripting.
There is no known workaround at this time.
All Opera users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=www-client/opera-9.25&quot;</code>
