The update also addresses two issues affecting Apple's Safari browser. The first is a flaw in the CFNetwork that could allow a malicious Website to control the displayed Website URL in a certificate warning.
"When Safari reaches a Website via a 302 redirection and a certificate warning is displayed, the warning will contain the original Website URL instead of the current Website URL," according to Apple. "This may allow a maliciously crafted Website that is reached via an open redirector on a user-trusted Website to control the displayed Website URL in a certificate warning."
Apple also pushed out Safari 4.0.2 Aug. 5 as well.
