Ubuntu Security Notice USN-3090-2
September 30, 2016

Pillow regression
==========================
==========================
========================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 14.04 LTS

Details:

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-2014-9=
601
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)
