CVE-2022-22137Network attack vector

Application crash via uninitialized pointer free

Published May 3, 2022 · Updated Apr 15, 2025

Memory corruption in Accusoft ImageGear 19.10 allows attackers to crash a host application by supplying a malformed IOCA file. In ioca_mys_rgb_allocate, a zero size_Y value creates a zero-byte table, leaves its first pointer uninitialized, and passes that pointer to operator_delete. The file must be processed by an application that embeds the library; the demonstrated consequence is an access-violation crash.
