TITLE

Apple iOS of libinfo Vulnerability in which important information is obtained

DESCRIPTION

libinfo in Apple iOS before 5.0.1 does not properly formulate domain-name queries, which allows remote attackers to obtain sensitive information via a crafted DNS hostname. Apple iOS is prone to an information-disclosure vulnerability that affects the Libinfo component. An attacker can exploit this issue to obtain sensitive information that may lead to further attacks. The following Apple systems are vulnerable: iOS 3.0 through 5.0 for iPhone 3GS, iPhone 4 and iPhone 4S iOS 3.1 through 5.0 for iPod touch (3rd generation) and late iOS 3.2 through 5.0 for iPad iOS 4.3 through 5.0 for iPad. Apple iOS is an operating system developed by Apple (Apple) for mobile devices. When accessing a maliciously crafted HTTP or HTTPS URL, CFNetwork could navigate to an incorrect server. CVE-ID CVE-2011-3246 : Erling Ellingsen of Facebook CoreGraphics Available for: iOS 3.0 through 5.0 for iPhone 3GS, iPhone 4 and iPhone 4S, iOS 3.1 through 5.0 for iPod touch (3rd generation) and later, iOS 3.2 through 5.0 for iPad, iOS 4.3 through 5.0 for iPad 2 Impact: Viewing a document containing a maliciously crafted font may lead to arbitrary code execution Description: Multiple memory corruption issues existed in FreeType, the most serious of which may lead to arbitrary code execution when processing a maliciously crafted font. DigiCert Malaysia has issued certificates with weak keys that it is unable to revoke. An attacker with a privileged network position could intercept user credentials or other sensitive information intended for a site with a certificate issued by DigiCert Malaysia. This issue is addressed by configuring default system trust settings so that DigiCert Malaysia's certificates are not trusted. We would like to acknowledge Bruce Morton of Entrust, Inc. for reporting this issue. This issue may lead to a bypass of codesigning checks. This issue does not affect devices running iOS prior to version 4.3. When resolving a maliciously crafted hostname, libinfo could return an incorrect result. CVE-ID CVE-2011-3441 : Erling Ellingsen of Facebook, Per Johansson of Blocket AB Passcode Lock Available for: iOS 4.3 through 5.0 for iPad 2 Impact: A person with physical access to a locked iPad 2 may be able to access some of the user's data Description: When a Smart Cover is opened while iPad 2 is confirming power off in the locked state, the iPad does not request a passcode. This allows some access to the iPad, but data protected by Data Protection is inaccessible and apps cannot be launched.
