GLSA-200708-17 : Opera: Multiple vulnerabilities

Synopsis :

The remote Gentoo host is missing one or more security-related
patches.

Description :

The remote host is affected by the vulnerability described in GLSA-200708-17
(Opera: Multiple vulnerabilities)

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 :

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.

Workaround :

There is no known workaround at this time for all these
vulnerabilities.

High / CVSS Base Score : 9.3
(CVSS2#AV:N/AC:M/Au:N/C:C/I:C/A:C)
