Description Adam Mariš 2016-02-05 10:01:50 UTC

A buffer overflow vulnerability was found in PcdDecode.c, where PCD decoder overruns shuffle buffer by writing 4 bytes into 3 byte per pixel wide buffer, allowing to write 768 bytes off the end of the buffer. This overwrites objects in Python's stack, leading to a crash.
