Il lettore ed il Acrobat dell'adobe permettono gli attacchi via PDFs

Severità: Mezzo

22 ottobre 2007

Sommario:

Ieri, l'adobe ha liberato un aggiornamento per riparare le vulnerabilità critiche di sicurezza che interessano il lettore 8.1 dell'adobe ed i Acrobat 8.1 (e tutte le versioni più iniziali) dell'adobe che funzionano su Windows XP. Attraendo uno dei vostri utenti nell'apertura della lima specialmente messa del pdf, un attacker può sfruttare il più difettoso di questi difetti guadagnare il controllo del sistema di quell'utente. Se usate il lettore o il Acrobat dell'adobe nella vostra rete, dovreste trasferire, verificare e schierare appena possibile la versione dal sistema centrale verso i satelliti 8.1.1.

Esposizione:

In a bollettino di sicurezza liberato ieri, l'adobe ha avvertito di parecchie vulnerabilità critiche in lettore 8.1 ed in Acrobat 8.1 (e tutte le versioni più iniziali) per Windows XP. While their advisory regularly mentions multiple vulnerabilities, they specifically refer to only one issue, which they describe in little detail. Adobe only says that if an attacker can convince a Windows XP user who also has Internet Explorer (IE) 7 into opening a specially crafted PDF file, the attacker can exploit this unspecified flaw to gain control of that user’s computer. Since you can embed PDF files into Web pages, simply visiting the wrong web page might trigger this flaw.

Petko D. Petkov (aka pdp) of GNUCITIZEN.org, first discovered this flaw last September. Following the tenets of responsible disclosure, he did not release any

Windows RealPlayer Vulnerability Discovered in the Wild

Severity: High

22 October, 2007

Summary:

Late Friday, RealNetworks released a patch for a critical vulnerability affecting RealPlayer 10.5 and RealPlayer 11 beta running on Windows. By enticing one of your users to a malicious Web site, an attacker can exploit this vulnerability to execute code on your user’s computer, with your user’s privileges. In the worst case scenario, the attacker could gain total control of the victim’s PC. If you allow the use of RealPlayer in your network, have your users upgrade immediately.

Exposure:

RealPlayer and RealOne Player are widely-used software for Internet media delivery. RealOne Player plays virtually every major Internet media format, including Windows Media, Quicktime, MPEG-4, and even DVDs. If you’ve watched streaming videos on the Internet, or listened to music samples while buying CDs online, you’ve probably encountered RealPlayer.

WatchGuard does not recommend using RealPlayer or RealOne Player, partly because both contain automatic communication features which, by default, let RealNetworks and RealNetwork’s “partners” (such as NASCAR and CNN) install software on your client computers. But in reality, many of your users have probably installed one of these products, with or without your permission.

In a security update released late Friday, RealNetworks warned of a new vulnerability that affects RealPlayer 10.5 and 11 beta running on Windows. (OS X and Linux users are not affected.) The flaw, discovered in the wild by

Firefox 2.0.0.8 Mends Ten Security Holes

Severity: Medium

19 October, 2007

Summary:

Late yesterday, the Mozilla Foundation released an update to fix ten security vulnerabilities in Firefox 2.0.0.7, for Windows, Linux, and Macintosh. If one of your Firefox users visits a malicious web page, an attacker could exploit the worst of these vulnerabilities to execute code on your user’s computer, with your user’s privileges, possibly gaining complete control of the computer. If you run Firefox on any platform, you should download and deploy version 2.0.0.8 at your earliest convenience.

Exposure:

Yesterday, the Mozilla Foundation released Firefox 2.0.0.8, fixing ten security vulnerabilities in the popular web browser. We summarize the three most critical vulnerabilities below:

  • Two memory corruption vulnerabilities. Firefox suffers from two unspecified crash bugs, which corrupt memory. Mozilla presumes that with enough effort some of these memory corruption flaws could be exploited to run arbitrary code. To exploit these flaws, an attacker would first have to trick one of your users into visiting a specially crafted web page. If your user took the bait, the attacker could execute code on that user’s machine, with that user’s privileges. If your user were a local administrator or had root privileges, the attacker would gain total control of the victim’s computer.
  • JavaScript privilege elevation vulnerability. According to Mozilla, an attacker can use a Script object to modify XPCNativeWrappers, which in turn could allow the attacker to execute JavaScript with

Removing the Annoying Delete Confirmation Dialog

Ever had the time when you have to delete a file and everytime you do an annoying pop-up tells, “Are you sure you want to move this file to the Recycle Bin?” not which in turn gives doubt that maybe you’re trying to delete the wrong file sometimes it’s a good thing, to prevent accidents, but can be a pain if you’re cleaning up unwanted files.

  • right-click on the Recycle Bin
  • choose Properties from the menu.
  • Recycle Bin Properties dialog
  • uncheck “Display delete confirmation dialog”

This tweak removes the delete confirmation but it doesn’t permanently delete the file. And you’re done, but after a long busy day of cleaning up your computer from trash and unused (unwanted) files. Maybe it’s time you enable it back, right? SO in order to enable the prompt back again just do the following steps above and remember to put a check on “Display delete confirmation dialog”. Easy ain’t it, now let the annoyance begin.
Now you can use another method, that does not go directly to the Recycle Bin, but it is directly or permanently deletes the file by Pressing the Shift Key + Delete. after you have selected the file(s).
