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.

The version of Tencent Linux installed on the remote TencentOS Server 3 host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the TSSA-2026:0972 advisory.

    Package updates are available for TencentOS Server 3 that fix the following vulnerabilities:

    CVE-2026-18301:
    A flaw was found in GIMP. A remote attacker could exploit an integer overflow vulnerability within the     `read_channel_data` function during PSD (Photoshop Document) file parsing by enticing a user to open a     specially crafted PSD file. This could lead to arbitrary code execution in the context of the current     process.

    CVE-2026-18303:
    A flaw was found in GIMP. This vulnerability, a stack-based buffer overflow in the TIF file parsing     component, allows a remote attacker to execute arbitrary code. User interaction is required, as the target     must open a specially crafted malicious TIF file. The issue stems from insufficient validation of user-     supplied data length before copying it to a buffer, leading to potential code execution in the context of     the current process.

    CVE-2026-18304:
    A flaw was found in GIMP. This vulnerability allows a remote attacker to execute arbitrary code by     tricking a user into opening a specially crafted TIF file. The issue arises from improper validation of     user-supplied data during TIF file parsing, which can lead to an integer overflow before memory     allocation. Successful exploitation could result in the attacker executing code in the context of the     current process.

    CVE-2026-18305:
    A flaw was found in GIMP, an image manipulation program. This vulnerability allows a remote attacker to     execute arbitrary code on an affected system. Exploitation requires user interaction, where the target     must open a specially crafted TIF (Tagged Image File Format) file. The flaw occurs during TIF file parsing     due to improper validation of user-supplied data, which can lead to an integer overflow and enable the     attacker to run malicious code.

    CVE-2026-18306:
    A flaw was found in GIMP. This vulnerability, an integer overflow within the parsing of SGI (Silicon     Graphics Image) files, allows a remote attacker to execute arbitrary code. Exploitation requires user     interaction, where the target must open a specially crafted malicious SGI file. Successful exploitation     could lead to the attacker executing code in the context of the current user's process.

    CVE-2026-18307:
    A flaw was found in GIMP. This heap-based buffer overflow vulnerability in the TIF file parsing component     allows a remote attacker to execute arbitrary code. User interaction is required, as the target must open     a specially crafted malicious TIF file. Successful exploitation can lead to arbitrary code execution in     the context of the current process.

    CVE-2026-58380:
    A flaw was found in GIMP's PNM file format parser. When parsing a specially crafted PNM file, the     pnmscanner_gettoken() function writes a null terminator one byte past the end of a stack-allocated buffer     due to an off-by-one error in the loop boundary check. This could lead to memory corruption, potentially     resulting in denial of service or arbitrary code execution.

    CVE-2026-66758:
    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.

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.
