Vulnerability from variot
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. CVE-ID CVE-2011-3440

"data": "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. \nAn attacker can exploit this issue to obtain sensitive information that may lead to further attacks. \nThe following Apple systems are vulnerable:\niOS 3.0 through 5.0 for iPhone 3GS, iPhone 4 and iPhone 4S\niOS 3.1 through 5.0 for iPod touch (3rd generation) and late\niOS 3.2 through 5.0 for iPad\niOS 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,\nCFNetwork could navigate to an incorrect server. \nCVE-ID\nCVE-2011-3246 : Erling Ellingsen of Facebook\n\nCoreGraphics\nAvailable for: iOS 3.0 through 5.0 for iPhone 3GS,\niPhone 4 and iPhone 4S,\niOS 3.1 through 5.0 for iPod touch (3rd generation) and later,\niOS 3.2 through 5.0 for iPad, iOS 4.3 through 5.0 for iPad 2\nImpact: Viewing a document containing a maliciously crafted font may\nlead to arbitrary code execution\nDescription: Multiple memory corruption issues existed in FreeType,\nthe most serious of which may lead to arbitrary code execution when\nprocessing a maliciously crafted font. DigiCert Malaysia has issued certificates with\nweak keys that it is unable to revoke. An attacker with a privileged\nnetwork position could intercept user credentials or other sensitive\ninformation intended for a site with a certificate issued by DigiCert\nMalaysia. This issue is addressed by configuring default system trust\nsettings so that DigiCert Malaysia\u0027s certificates are not trusted. We\nwould like to acknowledge Bruce Morton of Entrust, Inc. for reporting\nthis issue. This issue may lead to a bypass\nof codesigning checks. This issue does not affect devices running\niOS prior to version 4.3. When resolving a maliciously crafted hostname, libinfo could\nreturn an incorrect result. \nCVE-ID\nCVE-2011-3441 : Erling Ellingsen of Facebook, Per Johansson of\nBlocket AB\n\nPasscode Lock\nAvailable for: iOS 4.3 through 5.0 for iPad 2\nImpact: A person with physical access to a locked iPad 2 may be able\nto access some of the user\u0027s data\nDescription: When a Smart Cover is opened while iPad 2 is confirming\npower off in the locked state, the iPad does not request a passcode. \nThis allows some access to the iPad, but data protected by Data\nProtection is inaccessible and apps cannot be launched. \nCVE-ID\nCVE-2011-3440\n\nInstallation note:\n\nThis update is only available through iTunes, and will not appear\nin your computer\u0027s Software Update application, or in the Apple\nDownloads site. Make sure you have an Internet connection and have\ninstalled the latest version of iTunes from www.apple.com/itunes/\n\niTunes will automatically check Apple\u0027s update server on its weekly\nschedule. When an update is detected, it will download it. When\nthe iPhone, iPod touch or iPad is docked, iTunes will present the\nuser with the option to install the update. We recommend applying\nthe update immediately if possible. Selecting Don\u0027t Install will\npresent the option the next time you connect your iPhone, iPod touch,\nor iPad. \n\nThe automatic update process may take up to a week depending on the\nday that iTunes checks for updates.
