    Package        : gimp
    Version        : 2.10.22-4+deb11u5
    CVE ID         : CVE-2022-30067 CVE-2025-14422 CVE-2025-14425
    Debian Bug     :

    Several vulnerabilities were discovered in GIMP, the GNU Image
    Manipulation Program, which could result in buffer overflows and
    potentially the execution of arbitrary code if malformed XCF, PNM and
    JP2 files are opened.

    CVE-2022-30067

        GIMP 2.10.30 and 2.99.10 are vulnerable to Buffer Overflow. Through a
        crafted XCF file, the program will allocate for a huge amount of memory,
        resulting in insufficient memory or program crash.

    CVE-2025-14422

        GIMP PNM 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
        PNM 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-28273.

    CVE-2025-14425

        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-28248.


    For Debian 11 bullseye, these problems have been fixed in version
    2.10.22-4+deb11u5.

    We recommend that you upgrade your gimp packages.
