A flaw was found in GIMP's PSP (Paint Shop Pro) file parser. A remote attacker could exploit an integer overflow vulnerability in the read_creator_block() function by providing a specially crafted PSP image file. This vulnerability occurs when a 32-bit length value from the file is used for memory allocation without proper validation, leading to a heap overflow and an out-of-bounds write. Successful exploitation could result in an application level denial of service.

The AlmaLinux 9.6 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare ALMALINUX9.6:CLSA-2026:1791296305 advisory.

  - A flaw was found in GIMP's PSP (Paint Shop Pro) file parser. A remote attacker could exploit an integer     overflow vulnerability in the read_creator_block() function by providing a specially crafted PSP image     file. This vulnerability occurs when a 32-bit length value from the file is used for memory allocation     without proper validation, leading to a heap overflow and an out-of-bounds write. Successful exploitation     could result in an application level denial of service. (CVE-2026-2271)

  - A flaw was found in GIMP's PSP file format parser. A double-free condition occurs in the     read_layer_block() function when processing a specially crafted PSP file. This could allow an attacker to     cause memory corruption, potentially leading to denial of service or arbitrary code execution.

The AlmaLinux 9.2 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare ALMALINUX9.2:CLSA-2026:1785922090 advisory.

A remote attacker could exploit an integer     overflow vulnerability in the read_creator_block() function by providing a specially crafted PSP image     file. This vulnerability occurs when a 32-bit length value from the file is used for memory allocation     without proper validation, leading to a heap overflow and an out-of-bounds write. Successful exploitation     could result in an application level denial of service. (CVE-2026-2271)

  - A flaw was found in the file-fits plugin in GIMP. When processing a FITS image file, the plugin calculates     memory allocation sizes using signed 32-bit integers for width and height. If a crafted file sets both     values to large values, their product exceeds 2^31 and overflows, resulting in an undersized heap-based     buffer allocation. This integer overflow issue results in a heap-based buffer overflow when cfitsio     subsequently writes a full row of pixels in the buffer, causing memory corruption, potentially leading to     arbitrary code execution or a denial of service.

    GIMP: PSD loader: heap-buffer-overflow in fread_pascal_string() (no null terminator) (CVE-2026-2239)

    An integer overflow vulnerability has been identified in the PSP (Paint Shop Pro) file parser of GIMP. The     issue occurs in the read_creator_block() function, where the Creator metadata block is processed.
    Specifically, a 32-bit length value read from the file is used directly for memory allocation without     proper validation. (CVE-2026-2271)
