An error known as "a virtual function call on an invalid pointer" has
|
||
|
|
been discovered in the JavaScript engine (CVE-2007-4367). Furthermore,
|
||
|
|
iDefense Labs reported that an already-freed pointer may be still used
|
||
|
|
under unspecified circumstances in the BitTorrent support
|
||
|
|
(CVE-2007-3929). At last, minor other errors have been discovered,
|
||
|
|
relative to memory read protection (Opera Advisory 861) and URI
|
||
|
|
displays (CVE-2007-3142, CVE-2007-3819).

<impact type="normal">
|

|
<p>
|
||
|
|
A remote attacker could trigger the BitTorrent vulnerability by
|
||
|
|
enticing a user into starting a malicious BitTorrent download, and
|
||
|
|
execute arbitrary code through unspecified vectors. Additionally, a
|
||
|
|
specially crafted JavaScript may trigger the "virtual function"
|
||
|
|
vulnerability. The JavaScript engine can also access previously freed
|
||
|
|
but uncleaned memory. Finally, a user can be fooled with a too long
|
||
|
|
HTTP server name that does not fit the dialog box, or a URI containing
|
||
|
|
whitespaces.
|
||
|
|
</p>
|
||
|
|
</impact>
|
||
|
|
<workaround>
|
||
|
|
<p>
|
||
|
|
There is no known workaround at this time for all these
|
||
|
|
vulnerabilities.
|
||
|

|

</workaround>
|

<resolution>
|

|
|
<p>
|
||
|
|
All Opera users should upgrade to the latest version:
|
||
|
|
</p>
|
||
|
|
<code>
|
||
|
|
# emerge --sync
|
||
|
|
# emerge --ask --oneshot --verbose ">=www-client/opera-9.23"</code>
