CVE-2022-23400Public exploitNetwork attack vector

Application crash or canary disclosure via delimiter overflow

Published May 3, 2022 · Updated Apr 15, 2025

Stack-based buffer overflow in Accusoft ImageGear 19.10 allows context-dependent attackers to crash software or disclose data via a crafted PSD file. IGXMPXMLParser::parseDelimiter shifts a 256-byte destination after a leading slash but still copies up to 256 bytes, overwriting the adjacent stack canary. A target application must process attacker-supplied XMP metadata; the stack-cookie failure terminates the process, while some integrations disclose one canary byte.
