  • CFNetwork

    CVE-ID: CVE-2009-1723

    Available for: Mac OS X v10.5 through v10.5.7, Mac OS X Server v10.5 through v10.5.7

    Impact: A maliciously crafted website may control the displayed website URL in a certificate warning

    Description: 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. 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. This issue was addressed by returning the correct URL in the underlying CFNetwork layer. This issue does not affect systems prior to Mac OS X v10.5.
