Summary

Scribus before 1.6.7 and from 1.7.0 before 1.7.4 contains an integer overflow in the TIFF loader (CWE-190) that leads to a heap overflow. A local attacker can supply a tiled TIFF with large tile dimensions and sample values, and the flaw is triggered when a user imports the file. The corrupted heap memory can crash Scribus or execute code.
