CWE-ID: CWE-436 - Interpretation Conflict
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:L/VA:L/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to modify rendered image content or cause a denial of service.
The vulnerability exists due to interpretation conflict in the push-mode APNG parser when processing a crafted APNG image containing an ignored ancillary chunk with an unconsumed chunk body. A remote attacker can send a specially crafted PNG image to modify rendered image content or cause a denial of service.
User interaction is required to open the malicious image, and only push-mode applications using png_process_data are affected.
