Emergency Adobe Flash Player patch coming today

Less than a week after warning that hackers were embedding malicious Flash Player files (.swf) into Microsoft Word documents to launch targeted malware attacks, Adobe plans to release an emergency Flash Player patch today to fix the underlying problem.

The patch will fix a “critical” vulnerability in Flash Player and earlier versions for Windows, Mac OS X Linux and Solaris.

According to this Secunia advisory, the flaw allows a hacker to completely hijack a vulnerable Windows computer:

A vulnerability has been reported in Adobe Flash Player, which can be exploited by malicious people to compromise a user’s system.

The vulnerability is caused due to an error when parsing ActionScript that adds a custom function to the prototype of a predefined class. This results in incorrect interpretation of an object (i.e. object type confusion) when calling the custom function, which causes an invalid pointer to be dereferenced.

Secunia has posted a technical analysis of the flaw as well.

Adobe has confirmed that the vulnerability (CVE-2011-0611) could cause a crash and potentially allow an attacker to take control of the affected system.

There are reports that this vulnerability is being exploited in the wild in targeted attacks via a malicious Web page or a Flash (.swf) file embedded in a Microsoft Word (.doc) or Microsoft Excel (.xls) file delivered as an email attachment, targeting the Windows platform. At this time, Adobe is not aware of any attacks via PDF targeting Adobe Reader and Acrobat. Adobe Reader X Protected Mode mitigations would prevent an exploit of this kind from executing.

A patch for Google Chrome users is already available in Chrome version 10.0.648.205.

Adobe plans to fix the vulnerability in Adobe Acrobat and Adobe Reader at a later date.

Apple patches Pwn2Own iPhone OS vulnerabilities

Apple has released a critical update for its flagship iOS mobile operating system to fix several gaping security holes, including a few that were used in successful exploits at this year’s CanSecWest Pwn2Own contest.

The new iOS 4.3.2 software update, which is available for download via iTunes, provides cover for five documented security problems, including vulnerabilities exploited by Charlie Miller (iPhone) and a team of researchers who broke into RIM’s BlackBerry smartphone.

The raw details:

  • QuickLook: A memory corruption issue existed in QuickLook’s handling of Microsoft Office files. Viewing a maliciously crafted Microsoft Office file may lead to an unexpected application termination or arbitrary code execution.

  • WebKit: An integer overflow issue existed in the handling of nodesets. Visiting a maliciously crafted website may lead to an unexpected application termination or arbitrary code execution. Credit to Vincenzo Iozzo, Willem Pinckaers, Ralf-Philipp Weinmann, and an anonymous researcher working with TippingPoint’s Zero Day Initiative.
  • WebKit: A use after free issue existed in the handling of text nodes. Visiting a maliciously crafted website may lead to an unexpected application termination or arbitrary code execution. Credit to Vupen Security working with TippingPoint’s Zero Day Initiative, and Martin Barbella.

The iOS update also fixes the Comodo certificate trust policy problem that allowed an attacker with a privileged network position to intercept user credentials or other sensitive information. This issue was also fixed in separate Safari and Mac OS X updates.
