CVE-2021-28675: Fedoraproject Fedora

Medium severity, CVSS 5.5. EPSS: 1% chance of exploitation in the next 30 days.

An issue was discovered in Pillow before 8.2.0. PSDImagePlugin.PsdImageFile lacked a sanity check on the number of input layers relative to the size of the data block. This could lead to a DoS on Image.open prior to Image.load.

Affected products

• Fedoraproject Fedora: version 33 only
• Python Pillow: before 8.2.0 (fixed in 8.2.0)
