Vulnerability from variot
Safari in Apple iPhone OS 1.0 through 2.1 and iPhone OS for iPod touch 1.1 through 2.1 does not properly handle HTML TABLE elements, which allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted HTML document. 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. ----------------------------------------------------------------------

TITLE: Apple iPhone / iPod touch Multiple Vulnerabilities
SECUNIA ADVISORY ID: SA32756
VERIFY ADVISORY: http://secunia.com/advisories/32756/
CRITICAL: Highly critical
IMPACT: Security Bypass, Spoofing, Exposure of sensitive information, DoS, System access
WHERE:
From remote
OPERATING SYSTEM: Apple iPod touch http://secunia.com/advisories/product/16074/ Apple iPhone http://secunia.com/advisories/product/15128/
DESCRIPTION: Some weaknesses, security issues, and vulnerabilities have been reported in Apple iPhone and iPod touch, which can be exploited by malicious people to bypass certain security restrictions, disclose potential sensitive information, conduct spoofing attacks, to cause a DoS (Denial of Service), or potentially compromise a user's system.
1) A vulnerability in CoreGraphics can potentially be exploited to compromise a vulnerable system.
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.
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.

Two security-bypass vulnerabilities in the Passcode Lock functionality. \n4. An information-disclosure vulnerability in the Passcode Lock functionality. \n5. A memory-corruption vulnerability in Safari. \n6. A spoofing vulnerability in Safari. \n7. A security-bypass vulnerability in Safari. \nSuccessfully 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. \nThese issues affect the following:\niPhone OS 1.0 through 2.1\niPhone OS for iPod touch 1.1 through 2.1. ----------------------------------------------------------------------\n\nDo you need accurate and reliable IDS / IPS / AV detection rules?\n\nGet in-depth vulnerability details:\nhttp://secunia.com/binary_analysis/sample_analysis/\n\n----------------------------------------------------------------------\n\nTITLE:\nApple iPhone / iPod touch Multiple Vulnerabilities\n\nSECUNIA ADVISORY ID:\nSA32756\n\nVERIFY ADVISORY:\nhttp://secunia.com/advisories/32756/\n\nCRITICAL:\nHighly critical\n\nIMPACT:\nSecurity Bypass, Spoofing, Exposure of sensitive information, DoS,\nSystem access\n\nWHERE:\n\u003eFrom remote\n\nOPERATING SYSTEM:\nApple iPod touch\nhttp://secunia.com/advisories/product/16074/\nApple iPhone\nhttp://secunia.com/advisories/product/15128/\n\nDESCRIPTION:\nSome weaknesses, security issues, and vulnerabilities have been\nreported in Apple iPhone and iPod touch, which can be exploited by\nmalicious people to bypass certain security restrictions, disclose\npotential sensitive information, conduct spoofing attacks, to cause a\nDoS (Denial of Service), or potentially compromise a user\u0027s system. \n\n1) A vulnerability in CoreGraphics can potentially be exploited to\ncompromise a vulnerable system. \n\nFor more information see vulnerability #3 in:\nSA31326\n\n2) Several vulnerabilities in the processing of TIFF images can\npotentially be exploited to execute arbitrary code. \n\nFor more information:\nSA31610\n\n3) An error in the processing of TIFF images can cause a device\nreset. \n\n4) An unspecified error can result in the encryption level for PPTP\nVPN connections to be lower than expected. \n\n5) A signedness error in the Office Viewer component can potentially\nbe exploited to execute arbitrary code via a specially crafted\nMicrosoft Excel file. \n\nThis is related to vulnerability #10 in:\nSA32222\n\n6) A weakness exists in the handling of emergency calls, which can be\nexploited to bypass the Passcode lock and call arbitrary numbers when\nphysical access to the device is provided. \n\n8) A security issue can result in the content of an SMS message being\ndisplayed when the message arrives while the emergency call screen is\nshown. \n\n10) An error in Safari when handling embedded iframe elements can be\nexploited to spoof the user interface via content being displayed\noutside its boundaries. \n\n11) An error exists in Safari when launching an application while a\ncall approval dialog is shown. This can be exploited to call an\narbitrary number without user interaction. It is also possible to\nblock the user\u0027s ability to cancel the call. \n\n12) An error in Webkit can be exploited to disclose potentially\nsensitive data from form fields, although the \"Autocomplete\" feature\nis disabled. \n\nPROVIDED AND/OR DISCOVERED BY:\nThe vendor credits:\n1) Michal Zalewski, Google\n3) Sergio \u0027shadown\u0027 Alvarez, n.runs AG\n4) Stephen Butler, University of Illinois\n7) Nolen Scaife\n9) Haifei Li of Fortinet\u0027s FortiGuard Global Security Research Team\n10) John Resig, Mozilla Corporation\n11) Collin Mulliner, Fraunhofer SIT\n12) an anonymous researcher\n\nORIGINAL ADVISORY:\nApple:\nhttp://support.apple.com/kb/HT3318\n\nOTHER REFERENCES:\nSA31326:\nhttp://secunia.com/advisories/31326/\n\nSA31610:\nhttp://secunia.com/advisories/31610/\n\nSA32222:\nhttp://secunia.com/advisories/32222/\n\nSA32706:\nhttp://secunia.com/advisories/32706/\n\n----------------------------------------------------------------------\n\nAbout:\nThis Advisory was delivered by Secunia as a free service to help\neverybody keeping their systems up to date against the latest\nvulnerabilities. \n\nSubscribe:\nhttp://secunia.com/advisories/secunia_security_advisories/\n\nDefinitions: (Criticality, Where etc.)\nhttp://secunia.com/advisories/about_secunia_advisories/\n\n\nPlease Note:\nSecunia recommends that you verify all advisories you receive by\nclicking the link. \nSecunia NEVER sends attached files with advisories. \nSecunia does not advise people to install third party patches, only\nuse those supplied by the vendor. \n\n----------------------------------------------------------------------\n\nUnsubscribe: Secunia Security Advisories\nhttp://secunia.com/sec_adv_unsubscribe/?email=packet%40packetstormsecurity.org\n\n----------------------------------------------------------------------\n\n\n. ----------------------------------------------------------------------\n\nDo you have VARM strategy implemented?\n\n(Vulnerability Assessment Remediation Management) \n\nIf not, then implement it through the most reliable vulnerability\nintelligence source on the market. \n\nImplement it through Secunia. \n\nOther vulnerabilities have also been reported of which some may also\naffect Safari version 3.x. \n\nSOLUTION:\nUpgrade to Safari version 4, which fixes the vulnerabilities. \n\nPROVIDED AND/OR DISCOVERED BY:\n1-3) Tavis Ormandy\n4) Chris Evans of Google Inc.
