Summary

A flaw was found in GIMP's PSD parser. An integer overflow in read_RLE_channel() can cause an undersized heap allocation for the RLE row-length table, after which subsequent per-row writes corrupt heap memory.

This could lead to memory corruption, potentially resulting in denial of service or arbitrary code execution. Successful exploitation requires a user to open a specially crafted PSD file.

Red Hat severity: Important — CVSS 7.3 (CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H). Weakness: CWE-190.
