Adobe Systems pushed out a fix for an Adobe Flash Player zero-day faster
than expected.
Initially expected to come out the week of Sept. 27, today's patch fixes a
vulnerability the company warned Sept. 13 had come under attack. Though
the attacks have targeted Flash on Windows, the flaw impacts versions
10.1.82.76 and earlier on Windows, Macintosh, Linux and Solaris, as well
as version 10.1.92.10 on Android. Adobe Reader and Acrobat versions 9.3.4 and
earlier on Windows and Macintosh systems are affected as well, as are
Reader versions 9.3.4 and earlier on Unix.
"This vulnerability (CVE-2010-2884) could use a crash and potentially
allow an attacker to take control of the affected system," according to
the Adobe
advisory. "There are reports that this vulnerability is being actively
exploited in the wild against Flash Player on Windows. Adobe is not aware of
any attack exploiting this vulnerability against Adobe Reader or Acrobat to
date."
Still open is a separate
zero-day affecting versions of Adobe Reader and Acrobat. The fix for that
vulnerability is slated to come the week of Oct. 4. In the meantime, security
vendor RamzAfzar has released an unofficial patch for the vulnerability, while
Microsoft and Adobe have advised users to try Microsoft's Enhanced Mitigation
Experience Toolkit 2.0 as a stopgap while they wait for the patch.
