What is CVE-2017-15277?

The ImageMagick and GraphicsMagick libraries contain a flaw in the ReadGIFImage function that leads to an uninitialized palette when processing GIF files lacking both global and local palettes. This issue can result in sensitive data being inadvertently exposed from memory, posing significant risks if the software is used in applications handling confidential or critical information. Users should upgrade to patched versions to mitigate potential exposure.

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
