Adobe Flash Player before 10.2.154.27 on Windows, Mac OS X, Linux, and Solaris and 10.2.156.12 and earlier on Android; Adobe AIR before 2.6.19140; and Authplay.dll (aka AuthPlayLib.bundle) in Adobe Reader 9.x before 9.4.4 and 10.x through 10.0.1 on Windows, Adobe Reader 9.x before 9.4.4 and 10.x before 10.0.3 on Mac OS X, and Adobe Acrobat 9.x before 9.4.4 and 10.x before 10.0.3 on Windows and Mac OS X allow remote attackers to execute arbitrary code or cause a denial of service (application crash) via crafted Flash content; as demonstrated by a Microsoft Office document with an embedded .swf file that has a size inconsistency in a "group of included constants," object type confusion, ActionScript that adds custom functions to prototypes, and Date objects; and as exploited in the wild in April 2011.
- CVE-2012-0507CVSS 9.8KEVEPSS 98%
Unspecified vulnerability in the Java Runtime Environment (JRE) component in Oracle Java SE 7 Update 2 and earlier, 6 Update 30 and earlier, and 5.0 Update 33 and earlier allows remote attackers to affect confidentiality, integrity, and availability via unknown vectors related to Concurrency. NOTE: the previous information was obtained from the February 2012 Oracle CPU. Oracle has not commented on claims from a downstream vendor and third party researchers that this issue occurs because the AtomicReferenceArray class implementation does not ensure that the array is of the Object[] type, which allows attackers to cause a denial of service (JVM crash) or bypass Java sandbox restrictions. NOTE: this issue was originally mapped to CVE-2011-3571, but that identifier was already assigned to a different issue.
