Products Affected

Product Security, iPad, iPhone, iPod touch

iOS 6.1

Identity Services

Available for: iPhone 3GS and later, iPod touch (4th generation) and later, iPad 2 and later

Impact: Authentication relying on certificate-based Apple ID authentication may be bypassed

Description: An error handling issue existed in Identity Services. If the user's AppleID certificate failed to validate, the user's AppleID was assumed to be the empty string. If multiple systems belonging to different users enter this state, applications relying on this identity determination may erroneously extend trust. This issue was addressed by ensuring that NULL is returned instead of an empty string.

CVE-ID

CVE-2013-0963

International Components for Unicode

Available for: iPhone 3GS and later, iPod touch (4th generation) and later, iPad 2 and later

Impact: Visiting a maliciously crafted website may lead to a cross-site scripting attack

Description: A canonicalization issue existed in the handling of the EUC-JP encoding, which could lead to a cross-site scripting attack on EUC-JP encoded websites. This issue was addressed by updating the EUC-JP mapping table.

CVE-ID

CVE-2011-3058 : Masato Kinugawa

Kernel

Available for: iPhone 3GS and later, iPod touch (4th generation) and later, iPad 2 and later

Impact: A user-mode process may be able to access the first page of kernel memory

Description: The iOS kernel has checks to validate that the user-mode pointer and length passed to the copyin and copyout functions would not result in a user-mode process being able to directly access kernel memory. The checks were not being used if the length was smaller than one page. This issue was addressed through additional validation of the arguments to copyin and copyout.

CVE-ID

CVE-2013-0964 : Mark Dowd of Azimuth Security

Security

Available for: iPhone 3GS and later, iPod touch (4th generation) and later, iPad 2 and later

Impact: An attacker with a privileged network position may intercept user credentials or other sensitive information

Description: Several intermediate CA certificates were mistakenly issued by TURKTRUST. This may allow a man-in-the-middle attacker to redirect connections and intercept user credentials or other sensitive information. This issue was addressed by not allowing the incorrect SSL certificates.

StoreKit

Available for: iPhone 3GS and later, iPod touch (4th generation) and later, iPad 2 and later

Impact: JavaScript may be enabled in Mobile Safari without user interaction

Description: If a user disabled JavaScript in Safari Preferences, visiting a site which displayed a Smart App Banner would re-enable JavaScript without warning the user. This issue was addressed by not enabling JavaScript when visiting a site with a Smart App Banner.

CVE-ID

CVE-2013-0974 : Andrew Plotkin of Zarfhome Software Consulting, Ben Madison of BitCloud, Marek Durcek

WebKit

Available for: iPhone 3GS and later, iPod touch (4th generation) and later, iPad 2 and later
