Description
Pillow before 8.1.2 allows attackers to cause a denial of service (memory consumption) because the reported size of a contained image is not properly checked for an ICNS container, and thus an attempted memory allocation can be very large.
Affected configurations
• python pillow (< 8.1.1)
• fedoraproject fedora 32
• fedoraproject fedora 33
• fedoraproject fedora 34
