CVE-2022-36155Public exploit

Process crash via oversized vector allocation

Published Aug 16, 2022 · Updated Aug 3, 2024

Resource exhaustion in Monostream tifig 0.2.2 allows local users to crash image conversion by opening a crafted HEIC file. During HEVC decoding, a vector range insertion requests an allocation of SIZE_MAX from malformed input, causing operator new to abort. Exploitation requires the crafted file to be supplied and conversion to be triggered; the demonstrated consequence is termination of the tifig process.
