Description Mauro Matteo Cascella 2023-05-30 13:15:25 UTC

imapsync through 2.229 uses predictable paths under /tmp and /var/tmp in its default mode of operation. Both of these are typically world-writable, and thus (for example) an attacker can modify imapsync's cache and overwrite files belonging to the user who runs it.
