CVE-2021-21235: Kamadak-Exif Project Kamadak-Exif

Medium severity, CVSS 6.5. EPSS: 1.5% chance of exploitation in the next 30 days.

kamadak-exif is an exif parsing library written in pure Rust. In kamadak-exif version 0.5.2, there is an infinite loop in parsing crafted PNG files. Specifically, reader::read_from_container can cause an infinite loop when a crafted PNG file is given. This is fixed in version 0.5.3. No workaround is available. Applications that do not pass files with the PNG signature to Reader::read_from_container are not affected.
