Rectification Measures by Adobe PDF Software to Avoid Vulnerability Popravek Ukrepi, ki jih programska oprema Adobe PDF, da bi se izognili Ranljivost
Computer security researchers have discovered a vulnerability in Adobe system Inc's ubiquitous Acrobat Reader software that allows cyber intruders to attack PCs through rusted Web links. Računalniška varnost raziskovalci so odkrili ranljivost v Adobe sistema Inc's vseprisotnih Acrobat Reader, ki omogoča vsiljivcem kibernetski napad na računalnikih Zahrđao prek spletne povezave. The flaw appears to target Microsoft Corp's Internet Explorer 6.0 Web browser and earlier versions and Mozilla's Firefox browser. Ta napaka se pojavi na ciljno Microsoft Corp's Internet Explorer 6.0 spletni brskalnik in prejšnje različice in Mozilla's Firefox browser.
Virtually any Web site hosting Portable Document Format (PDF) files are vulnerable to attack, according to researchers from Praktično katero koli spletno mesto gosti Portable Document Format (PDF) datoteke so izpostavljeni napadom, v skladu z raziskovalci iz Symantec Corp Symantec Corp and VeriSign Inc's iDefense Intelligence. in VeriSign Inc iDefense's Intelligence.
The attacks could range from stealing cookies that track a user's web browsing history to the creation of harmful worms, they said. Napadi lahko segajo od krasti piškotki, ki beležijo uporabnik spletnega brskalnika zgodovini k ustvarjanju škodljivih črvi, so rekli. The flaw exists in a plug-in that enables Acrobat users to view PDF files within Web browsers. Ta napaka ne obstaja v plug-in, da omogoča uporabnikom, da si ogledate Acrobat PDF datotek v spletne brskalnike. By manipulating the Web links to those documents, hackers and online thieves are able to commandeer the Acrobat software and run malicious code when users attempt to open the files, according to Ken Dunham, director of the rapid response team at iDefense Intelligence. Z manipulirajo s spletnimi povezavami do teh dokumentov, hekerji in online tatovi so sposobni Rekvirirati Acrobat programske opreme in zagon zlonamerne kode, ko uporabniki poskušajo odpreti datoteke, v skladu s Ken Dunham, direktor za hiter odziv na ekipo iDefense Intelligence.
Dunham gave his hypothetical scenario: An attacker finds a PDF file on a banking Web site. Dunham je njegov hipotetični scenarij: An napadalca najde PDF datoteke na bančnih spletnih strani. The attacker creates a hostile Web site that links to the bank's PDF file. Napadalca ustvarja sovražno spletne strani, da povezave do banke na PDF datoteko. Included is malicious JavaScript code that will run on the unsuspecting user's computer once the link is clicked. Vključena je zlonamerno JavaScript kodo, ki bo potekal na Bezazlen uporabnikov računalnik, ko je kliknil na povezavo. “PDF is trusted, tried and true – everyone uses it,” Dunham said. "PDF se zaupate, preizkušen in res - vse namene," je dejal Dunham. “But instead of just viewing the file, you've initiated script that shouldn't be executed. "Ampak namesto samo ogled datoteke, ki ste jo sprožila skript, da ne bi smela biti izvršena. All you have to do is click on the PDF and the ball starts rolling.” Vse kar morate storiti, je klik na PDF in kroglica se začne vozni. "
In response to this finding, Adobe Systems has announced that it will issue patches next week for older versions of its Reader and Acrobat Reader software to update to the latest versions of Adobe Reader and Acrobat to avoid being affected by this cross-site scripting flaw in its software that allows attackers to run malicious JavaScript on a user's PC. V odgovor na te ugotovitve, Adobe Systems je napovedal, da bo vprašanje obliži naslednji teden za starejše različice svojih Reader in Acrobat Reader posodobiti na najnovejšo različico Adobe Acrobat Reader, in da ne bi vplivala na cross-site skriptno napako v svoje programske opreme, ki omogoča napadači teči zlonamerno JavaScript na uporabnikov računalnik.
Adobe System is seriously looking into this issue. Adobe System resno proučuje to vprašanje. Since the problem affects versions 7.0.8 and earlier of the Acrobat and Reader programs, Adobe is urging users of those versions to disable the Acrobat and Reader plug-in in their Web browser until the patches are issued. Ker je težava različica 7.0.8 in starejše od Acrobat Reader in programi, Adobe pozivajo uporabnike teh različic onemogočiti in Acrobat Reader plug-in v njihovi spletni brskalnik, dokler obliži so izdana. Adobe has also been encouraging customers to upgrade to Reader 8 , the latest version of its program, which is not affected by the vulnerability. Adobe je bilo tudi spodbujanje odjemalcev nadgraditi Reader 8, najnovejšo različico svojega programa, ki ni prizadeta zaradi ranljivosti.
Adobe is also warning users to exercise caution when clicking on untrusted links, since those links could be manipulated to run an exploit. Adobe je prav tako opozorilo uporabnikom, da previdni, ko kliknete na Untrusted povezave, ker te povezave lahko manipulira za vodenje izkoristiti. Security vendor Websense Inc. wrote on Thursday that an attacker could also gain access to files on a machine. Varnost prodajalca Websense Inc pisala v četrtek, da se napadalec lahko tudi dostop do datotek na stroju.
Exploits will apparently only work with certain combinations of Web browsers and Adobe software, but Adobe did not specify which combinations. Izkorišča bo očitno deluje le z nekaterimi kombinacijami Spletni brskalniki in Adobe programske opreme, vendar pa Adobe ni opredelila, katere kombinacije.

While this method does work, it's not really the best especially if your ebook has a couple hundred pages. Medtem ko se ta metoda ne dela, to ni ravno najboljša, zlasti če je vaša ebook ima nekaj sto strani. Is there any other way involving actual hacking or cracking and copying the text itself? Ali obstaja kakšen drug način, ki vključuje dejanski ali Isjeckan krekingom in kopiranje besedila sam?
