The XSL stylesheet implementation in WebKit in Apple Safari before 4.0, iPhone OS 1.0 through 2.2.1, and iPhone OS for iPod touch 1.1 through 2.2.1 does not properly handle XML external entities, which allows remote attackers to read arbitrary files via a crafted DTD, as demonstrated by a file:///etc/passwd URL in an entity declaration, related to an XXE attack.
The product processes an XML document that can contain XML entities with URIs that resolve to documents outside of the intended sphere of control, causing the product to embed incorrect documents into its output.
