A stack buffer overflow vulnerability exists in GIMP's PNM file format parser due to an off-by-one error in the pnmscanner_gettoken() function. This flaw can cause memory corruption when processing specially crafted PNM files, potentially leading to denial of service or arbitrary code execution. Red Hat has issued a security update addressing this issue in GIMP for Red Hat Enterprise Linux 9.

The vulnerability (CVE-2026-58380) arises from an off-by-one error in the loop boundary check within the pnmscanner_gettoken() function of GIMP's PNM file parser. This causes a null terminator to be written one byte beyond a stack-allocated buffer, resulting in a stack buffer overflow. This memory corruption flaw can be exploited to cause denial of service or arbitrary code execution. Red Hat has released a security update for GIMP in Red Hat Enterprise Linux 9 to fix this issue.

Red Hat Security Advisory: gimp security update

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.

CVE-2026-58384 is an integer overflow vulnerability in the read_RLE_channel() function of GIMP's PSD parser on Red Hat Enterprise Linux 9. The overflow causes an undersized heap allocation for the RLE row-length table, which leads to heap memory corruption during subsequent writes. This memory corruption can potentially be exploited to cause denial of service or arbitrary code execution. Red Hat has published an important security advisory (RHSA-2026:40751) that includes a patch updating GIMP to version 3.0.4-4.el9_8.7, which fixes this vulnerability across multiple RHEL 9 variants and architectures.
