Description

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.
