Fluid Attacks Database

Description

Insufficient Verification of Data Authenticity in Pillow An issue was discovered in Pillow before 8.2.0. For BLP data, BlpImagePlugin did not properly check that reads (after jumping to file offsets) returned data. This could lead to a DoS where the decoder could be run a large number of times on empty data.

Mitigation

Update Impact

Minimal update. May introduce new vulnerabilities or breaking changes.
