A critical heap buffer overflow vulnerability was discovered and patched in a vendored giflib library, where attacker-controlled GIF header fields could trigger memcpy operations that write beyond allocated heap buffers. Because the affected application fetches GIF images from external servers, this vulnerability was remotely exploitable — making it a high-priority fix for any mobile application shipping this code. The patch introduces proper bounds validation before memory copy operations, clos
