VLC Media Player/Kodi/PopcornTime 'Red Chimera' < 2.2.5 Memory Corruption (PoC)
|
|
Author: SivertPL (kroppoloe@protonmail.ch)
|
|
CVE: CVE-2017-8311
|
|
|
|
Infamous VLC/Kodi/PopcornTime subtitle attack in libsubtitle_plugin.dll.
|
|
This is the Proof of Concept of the reverse engineered heap corruption vulnerability affecting JacoSUB parsing in VLC/Kodi/PopcornTime.
|
|
The crash is exploitable, but hard to exploit because of various environmental constraints such as threading/mitigations/scriptless.
|
|
I want to join a research team.
