caused a regression which resulted in failures when processing certain

pending further investigation.

We apologize for the inconvenience.

Original advisory details:

It was discovered that a flaw in processing a compressed text chunk in
a PNG image could cause the image to have a large size when decompressed,
potentially leading to a denial of service. (CVE-2014-9601)

Andrew Drake discovered that Pillow incorrectly validated input. A remote
attacker could use this to cause Pillow to crash, resulting in a denial
of service. (CVE-2014-3589)

Eric Soroos discovered that Pillow incorrectly handled certain malformed
FLI, Tiff, and PhotoCD files. A remote attacker could use this issue to
cause Pillow to crash, resulting in a denial of service.
(CVE-2016-0740, CVE-2016-0775, CVE-2016-2533)");
