A denial of service vulnerability was reported in the Python Image Library and all versions of its fork, Pillow. If a user were able to supply date to the Image.open routine or similar APIs they could cause the application to crash due to inadequate input validation in the IcnsImagePlugin module. This has been corrected in upstream version 2.3.2 [1] and 2.5.2 [2]; a patch is available [3]. [1] https://pypi.python.org/pypi/Pillow/2.3.2 [2] https://pypi.python.org/pypi/Pillow/2.5.2 [3] https://github.com/python-pillow/Pillow/commit/205e056f8f9b06ed7b925cf8aa0874bc4aaf8a7d Acknowledgements: Red Hat would like to thank Andrew Drake of Dropbox for reporting this issue.

This is an infinite loop. The code did not properly check size values read from the input file. A malicious ICNS (Apple Icon Image) file could cause python-pillow / python-imaging to repeatedly read the same block of input file and never advance, leading to high CPU usage DoS. Affects python-pillow and python-imaging packages as shipped in Red Hat Enterprise Linux 5 and later.
