CVE-2021-28676

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

Description An issue was discovered in the FliDecode component of the Pillow image processing library, related to incorrect checking of non-zero block advance for FLI data. This could potentially lead to an infinite loop when loading data. The issue may allow a remote attacker to cause a denial of service.

Recommendations For versions prior to 8.2.0, update to version 8.2.0 or later to resolve the issue. As a temporary workaround, consider avoiding the use of FLI data with the FliDecode component until a patch is applied.
