CVE-2026-58384
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.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.26%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
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.
