"USN-3090-1 fixed vulnerabilities in Pillow. The patch to fix
CVE-2014-9601 caused a regression which resulted in failures when
processing certain png images. This update temporarily reverts the
security fix for CVE-2014-9601 pending further investigation.

We apologize for the inconvenience.

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).

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.");
