TITLE

Apple iOS Vulnerability in obtaining important information in the keyboard component

DESCRIPTION

The Keyboards component in Apple iOS before 5 displays the final character of an entered password during a subsequent use of a keyboard, which allows physically proximate attackers to obtain sensitive information by reading this character. Apple iOS is prone to an information-disclosure vulnerability. A local attacker can exploit this issue to retrieve the last character of a password typed previously by another user. Information obtained may aid in further attacks. The following Apple systems are vulnerable: iOS 3.0 through 4.3.5 for iPhone 3GS and iPhone 4, iOS 3.1 through 4.3.5 for iPod touch (3rd generation) and later, iOS 3.2 through 4.3.5 for iPad NOTE: This issue was previously discussed in BID 50086 (Apple iPhone/iPad/iPod touch Prior to iOS 5 Multiple Vulnerabilities) but has been given its own record to better document it. ---------------------------------------------------------------------- Ovum says ad hoc tools are out-dated. The best practice approach? Fast vulnerability intelligence, threat handling, and setup in one tool.

This can be exploited to insert arbitrary HTML and script code, which will be executed in a user's browser session in context of an affected site when the malicious invitation is being viewed. 3) The CFNetwork component stores a user's AppleID password and username in the log file readable by applications, which can be exploited to disclose the credentials. 4) The CFNetwork component does not properly restrict cross-domain access of HTTP cookies, which can be exploited to access the cookies of another web site. 5) An error exists within CoreFoundation when handling string tokenization. For more information see vulnerability #1 in: SA46339 6) Multiple errors within CoreGraphics when handling the certain freetype fonts can be exploited to corrupt memory. 7) An error within CoreMedia does not properly handle cross-site redirects and can be exploited to disclose video data. 8) An error exits within the Data Access component when handling multiple accounts configured on the same server and can be exploited to disclose the cookie of another account. 9) The application accepts X.509 certificates with MD5 hashes, which could lead to weak cryptographic certificates being used. This can be exploited to disclose encrypted information e.g. using a Man-in-the-Middle (MitM) attack. 10) A design error exists within the implementation of SSL 3.0 and TLS 1.0 protocols. For more information: SA46168 11) An error within ImageIO when handling CCITT Group 4 encoded TIFF files can be exploited to cause a buffer overflow. For more information see vulnerability #1 in: SA43593 12) An error in ImageIO within the handling of CCITT Group 4 encoded TIFF image files can be exploited to cause a heap-based buffer overflow. For more information see vulnerability #9 in: SA45325 13) An error within ICU (International Components for Unicode) can be exploited to cause a buffer overflow. For more information see vulnerability #11 in: SA45054 14) An error within the kernel does not reclaim memory from incomplete TCP connections, which can be exploited to exhaust system resources by connecting to a listening service and cause the device to reset. 15) A NULL-pointer dereference error within the kernel when handling IPv6 socket options can be exploited to cause the device to reset. 16) An error within libxml can be exploited to cause a heap-based buffer overflow. For more information see vulnerability #12 in: SA45325 17) An error within OfficeImport when viewing certain Microsoft Word files can be exploited to cause a buffer overflow. 18) An error within OfficeImport when viewing certain Microsoft Excel files can be exploited to cause a buffer overflow. 19) An indexing error exists in the OfficeImport framework when processing certain records in a Microsoft Word file. For more information see vulnerability #19 in: SA45054 20) An error in the OfficeImport framework when processing records can be exploited to corrupt memory. For more information see vulnerability #28 in: SA43814 21) An error within Safari does not properly handle the "attachment" HTTP Content-Disposition header and can be exploited to conduct cross-site scripting attacks. 22) The parental restrictions feature stores the restrictions passcode in plaintext on disk and can be exploited to disclose the passcode. 23) An error within UIKit does not properly handle "tel:" URIs and can be exploited to cause the device to hang by tricking the user into visiting a malicious website. 24) Some vulnerabilities are caused due to a bundled vulnerable version of WebKit. For more information: SA43519 SA43683 SA43696 SA43859 SA45097 SA45325 SA45325 SA45498 SA45498 SA46339 SA46412 25) The WiFi credentials are stored in a file readable by other applications, which may lead to the credentials being disclosed. Successful exploitation of vulnerabilities #6, #16 \x96 #20, and #24 may allow execution of arbitrary code. SOLUTION: Apply iOS 5 Software Update.
