ELSA-2025-7417 advisory.

  - GIMP PSP 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 PSP files. The issue results from the lack of proper validation
    of user-supplied data, which can result in an integer overflow before writing to memory. An attacker can
    leverage this vulnerability to execute code in the context of the current process. . Was ZDI-CAN-22096.
    (CVE-2023-44443)

  - GIMP PSD 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 PSD 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 arbitrary code in the context of the current process. Was ZDI-
    CAN-22094. (CVE-2023-44442)

  - GIMP DDS 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 DDS 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-22093.
    (CVE-2023-44441)

  - GIMP PSP File Parsing Off-By-One 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 PSP files. Crafted data in a PSP file can trigger an off-by-one
    error when calculating a location to write within a heap-based buffer. An attacker can leverage this
    vulnerability to execute code in the context of the current process. . Was ZDI-CAN-22097. (CVE-2023-44444)
