"Two buffer overflows were discovered in python-imaging, a Python
library for loading and manipulating image files, which may lead to
the execution of arbitrary code.

CVE-2016-0775   Buffer overflow in FliDecode.c

The second buffer overflow was in PcdDecode.c. A CVE identifier has
not been assigned yet.

For Debian 6 'Squeeze', these problems have been fixed in version
1.1.7-2+deb6u2.

We recommend that you upgrade your python-imaging packages.

NOTE: Tenable Network Security has extracted the preceding description
block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues."
