CVE-2020-29384: An issue was discovered in PNGOUT 2020-01-15.

Security readout for executives and security teams

PNGOUT 2020-01-15 can overflow an integer while compressing a specially crafted PNG file. The public record does not state severity, business impact, or a confirmed fix. The main concern is automated or user-facing image-processing workflows that run PNGOUT on files from outside trusted control. Exposure is most likely where PNGOUT 2020-01-15 is installed on desktops, build systems, CI jobs, asset pipelines, or upload-processing services that compress PNG files from users, customers, partners, or the internet. Prioritize assessment if PNGOUT is used in automated processing of external images. If usage is limited to trusted manual workflows, urgency is lower but still requires tracking because severity and fix information are incomplete. Mitigation focus: Inventory systems and pipelines for PNGOUT 2020-01-15 usage.; Avoid processing untrusted PNG files with affected PNGOUT builds.; Check the PNGOUT project pages for current vendor guidance or replacement versions..
