Description Alexander Bergmann 2016-02-24 08:25:18 UTC
http://www.openwall.com/lists/oss-security/2016/02/02/5

There is a buffer overflow in PcdDecode.c, where the decoder writes
assuming 4 bytes per pixel into a 3 byte per pixel wide buffer,
allowing writing 768 bytes off the end of the buffer. This overwrites
objects in Python's stack, leading to a crash. 

All versions of Python Pillow <= 3.1.0 and PIL == 1.1.7 (at the least) are affected.

This issue and the patch are public:
https://github.com/python-pillow/Pillow/pull/1706
