CVE-2008-1586

TITLE

Apple iPhone OS of ImageIO In Service operation interruption (DoS) Vulnerabilities

DESCRIPTION

ImageIO in Apple iPhone OS 1.0 through 2.1 and iPhone OS for iPod touch 1.1 through 2.1 allow remote attackers to cause a denial of service (memory consumption and device reset) via a crafted TIFF image. Apple iPhone and iPod touch are prone to multiple vulnerabilities: 1. A denial-of-service vulnerability in the ImageIO module. 2. A weakness in Networking. 3. Two security-bypass vulnerabilities in the Passcode Lock functionality. 4. An information-disclosure vulnerability in the Passcode Lock functionality. 5. A memory-corruption vulnerability in Safari. 6. A spoofing vulnerability in Safari. 7. A security-bypass vulnerability in Safari. Successfully exploiting these issues may allow attackers to execute arbitrary code, bypass security restrictions, obtain sensitive information, perform spoofing attacks, or cause denial-of-service conditions. These issues affect the following: iPhone OS 1.0 through 2.1 iPhone OS for iPod touch 1.1 through 2.1. A memory exhaustion vulnerability exists in the way TIFF graphics are handled, and viewing specially crafted TIFF graphics may cause the device to restart unexpectedly. ---------------------------------------------------------------------- Do you need accurate and reliable IDS / IPS / AV detection rules?

For more information see vulnerability #3 in: SA31326 2) Several vulnerabilities in the processing of TIFF images can potentially be exploited to execute arbitrary code. For more information: SA31610 3) An error in the processing of TIFF images can cause a device reset. 4) An unspecified error can result in the encryption level for PPTP VPN connections to be lower than expected. 5) A signedness error in the Office Viewer component can potentially be exploited to execute arbitrary code via a specially crafted Microsoft Excel file. This is related to vulnerability #10 in: SA32222 6) A weakness exists in the handling of emergency calls, which can be exploited to bypass the Passcode lock and call arbitrary numbers when physical access to the device is provided. 8) A security issue can result in the content of an SMS message being displayed when the message arrives while the emergency call screen is shown. 9) An error in Safari when handling HTML table elements can be exploited to cause a memory corruption and potentially execute arbitrary code when a user visits a specially crafted web site. 10) An error in Safari when handling embedded iframe elements can be exploited to spoof the user interface via content being displayed outside its boundaries. 11) An error exists in Safari when launching an application while a call approval dialog is shown. This can be exploited to call an arbitrary number without user interaction. It is also possible to block the user's ability to cancel the call. 12) An error in Webkit can be exploited to disclose potentially sensitive data from form fields, although the "Autocomplete" feature is disabled.
