The Rocky Linux 9.6 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare ALMALINUX9.6:CLSA-2026:1778861508 advisory.

  - A flaw was found in GIMP. A remote attacker could exploit an integer overflow vulnerability in the FITS     image loader by providing a specially crafted FITS file. This integer overflow leads to a zero-byte memory     allocation, which is then subjected to a heap buffer overflow when processing pixel data. Successful     exploitation could result in a denial of service (DoS) or potentially arbitrary code execution.
    (CVE-2026-40915)

  - GIMP PSD File Parsing Integer Overflow Remote Code Execution Vulnerability. This vulnerability allows     remote attackers to execute arbitrary code on affected installations of GIMP. User interaction is required     to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The     specific flaw exists within the parsing of PSD files. The issue results from the lack of proper validation     of user-supplied data, which can result in an integer overflow before allocating a buffer. An attacker can     leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-28807.
    (CVE-2026-4150)

  - GIMP JP2 File Parsing Heap-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability     allows remote attackers to execute arbitrary code on affected installations of GIMP. User interaction is     required to exploit this vulnerability in that the target must visit a malicious page or open a malicious     file. The specific flaw exists within the parsing of JP2 files. The issue results from the lack of proper     validation of the length of user-supplied data prior to copying it to a heap-based buffer. An attacker can     leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-28863.
    (CVE-2026-4152)

  - GIMP PSP File Parsing Heap-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability     allows remote attackers to execute arbitrary code on affected installations of GIMP.

User interaction is required     to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The     specific flaw exists within the parsing of XPM files. The issue results from the lack of proper validation     of user-supplied data, which can result in an integer overflow before allocating a buffer. An attacker can     leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-28901.
    (CVE-2026-4154)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - A flaw was found in GIMP. A remote attacker could exploit an integer overflow vulnerability in the FITS     image loader by providing a specially crafted FITS file. This integer overflow leads to a zero-byte memory     allocation, which is then subjected to a heap buffer overflow when processing pixel data. Successful     exploitation could result in a denial of service (DoS) or potentially arbitrary code execution.
    (CVE-2026-40915)

Note that Nessus relies on the presence of the package as reported by the vendor.

The version of gimp installed on the remote host is prior to 2.8.22-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2GIMP-2026-017 advisory.

    A flaw was found in GIMP. A remote attacker could exploit an integer overflow vulnerability in the FITS     image loader by providing a specially crafted FITS file. This integer overflow leads to a zero-byte memory     allocation, which is then subjected to a heap buffer overflow when processing pixel data. Successful     exploitation could result in a denial of service (DoS) or potentially arbitrary code execution.
    (CVE-2026-40915)

    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.
