There is no fixed version for Echo:latest psd-tools.
NVD Description
Note: Versions mentioned in the description apply only to the upstream psd-tools package and not the psd-tools package as distributed by Echo.
See How to fix? for Echo:latest relevant fixed versions and status.
psd-tools is a Python package for working with Adobe Photoshop PSD files. Prior to version 1.17.1, SmartObject.save() writes an embedded smart object to a path taken verbatim from the PSD file. Because that name is attacker-controlled and unsanitised, a tool that extracts embedded objects from an untrusted .psd can be made to write attacker-chosen bytes to an attacker-chosen path (absolute or ../-traversing), outside its intended output directory. A secondary issue in SmartObject.open() for external-kind smart objects allows the attacker-controlled fullPath descriptor to be used as an arbitrary file read path, enabling exfiltration of the read content to the controlled write destination. Both issues are fixed in v1.17.1.
