Security readout for executives and security teams
This issue affects Pillow versions before 2.7.0 when processing PNG files. A specially crafted PNG with compressed text metadata can expand to a very large size during decompression, exhausting resources and causing a denial of service in software that processes untrusted images. Exposure is most likely in Python applications, web services, or background workers that use Pillow before 2.7.0 to process user-supplied PNG images, especially upload, thumbnailing, moderation, or conversion workflows. Treat this as a moderate availability risk. It is old and not KEV-listed, but internet-facing image upload or processing services running outdated Pillow should be prioritized for upgrade because exploitation could disrupt service availability. Mitigation focus: Upgrade Pillow to 2.7.0 or a later vendor-supported version.; Apply relevant distribution updates from Fedora, openSUSE, Oracle, or your package vendor.; Restrict untrusted PNG processing until vulnerable Pillow deployments are upgraded..
