EPSS

EPSS is a scoring model that predicts the likelihood of a vulnerability being exploited.

EPSS Score

The EPSS model produces a probability score between 0 and 1 (0 and 100%). The higher the score, the greater the probability that a vulnerability will be exploited.

EPSS Percentile

The percentile is used to rank CVE according to their EPSS score. For example, a CVE in the 95th percentile according to its EPSS score is more likely to be exploited than 95% of other CVE. Thus, the percentile is used to compare the EPSS score of a CVE with that of other CVE.

Source: https://code.google.com/p/google-security-research/issues/detail?id=545 There is a type confusion issue during serialization if ObjectEncoder.dynamicPropertyWriter is overridden with a value that is not a function. In the following ActionScript: flash.net.ObjectEncoding.dynamicPropertyWriter = new subdpw(); var b = new ByteArray(); var a = {}; a.test = 1; b.writeObject(a); The object 'a' with a dynamic property 'test' is serialized using a custom dynamicPropertyWriter of class subpwd. However this class overrides writeDynamicProperties with a property that is not a function leading to type confusion (note that this is not possible in the compiler, the bytecode needs to be modified manually). To reproduce the issue, load objectencoding.swf. PoC code is also attached. To use this code, compile the swf, and decompress it (for example, using flasm -x), and then search for the string "triteDocumentProperties" in the SWF and change it to "writeDocumentProperties".
