>
> Description: Multiple input validation issues exist in WebKit's handling of FTP directory listings. Accessing a maliciously crafted FTP server may lead to information disclosure, unexpected application termination, or execution of arbitrary code. This update addresses the issues through improved parsing of FTP directory listings.
>
> **4. ImageIO**
>
> CVE-ID: CVE-2009-2285
>
> Available for: iPhone OS 1.0 through 3.1.2, iPhone OS for iPod touch 1.1 through 3.1.2
>
> Impact: Viewing a maliciously crafted TIFF image may lead to an unexpected application termination or arbitrary code execution
>
> Description: A buffer underflow exists in ImageIO's handling of TIFF images. Viewing a maliciously crafted TIFF image may lead to an unexpected application termination or arbitrary code execution. This issue is addressed through improved bounds checking.
>
> **5. WebKit**
>
> CVE-ID: CVE-2009-2841
>
> Available for: iPhone OS 1.0 through 3.1.2, iPhone OS for iPod touch 1.1 through 3.1.2
>
> Impact: Mail may load remote audio and video content when remote image loading is disabled
>
> Description: When WebKit encounters an HTML 5 Media Element pointing to an external resource, it does not issue a resource load callback to determine if the resource should be loaded. This may result in undesired requests to remote servers. As an example, the sender of an HTML-formatted email message could use this to determine that the message was read. This issue is addressed by generating resource load callbacks when WebKit encounters an HTML 5 Media Element.
