CVE-2021-28677

Name of the Vulnerable Software and Affected Versions Pillow versions prior to 8.2.0

Description The issue is related to the readline implementation in the EPSImageFile component of the Pillow library. It uses a quadratic method to accumulate lines while searching for a line ending, which can be exploited by a malicious EPS file to perform a denial of service (DoS) attack. This can happen before an image is accepted for opening. A remote attacker could use this vulnerability to cause a DoS.

Recommendations For Pillow versions prior to 8.2.0, update to version 8.2.0 or later to resolve the issue. As a temporary workaround, consider restricting the use of EPS files until the update is applied.
