# CVE-2026-58384: Gimp: gimp: integer overflow in read_rle_channel()

Status: published. Published: 2026-07-07. Updated: 2026-11-02.

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.

## Remediation

- workaround: None — requires opening a crafted PSD file. (source: CNA: redhat)
