An issue was discovered in PoDoFo 0.9.6. There is an attempted excessive memory allocation in PoDoFo::podofo_calloc in base/PdfMemoryManagement.cpp when called from PoDoFo::PdfPredictorDecoder::PdfPredictorDecoder in base/PdfFiltersPrivate.cpp.

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

  - An issue was discovered in PoDoFo 0.9.6. There is an attempted excessive memory allocation in     PoDoFo::podofo_calloc in base/PdfMemoryManagement.cpp when called from     PoDoFo::PdfPredictorDecoder::PdfPredictorDecoder in base/PdfFiltersPrivate.cpp. (CVE-2018-20797)

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

The remote Ubuntu 14.04 LTS / 16.04 LTS / 18.04 LTS / 20.04 LTS / 22.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-7217-1 advisory.

    It was discovered that the PoDoFo library could dereference a NULL pointer when getting the number of     pages in a PDF. If a user or application were tricked into opening a crafted PDF file, an attacker could     possibly use this issue to cause a denial of service. This issue only affected

    Ubuntu 14.04 LTS, Ubuntu 16.04 LTS, Ubuntu 18.04 LTS and Ubuntu 20.04 LTS. (CVE-2018-11255)

    It was discovered that PoDoFo library incorrectly handled memory when computing an encryption key, which     could lead to a buffer overflow. If a user or application were tricked into opening a crafted PDF file, an     attacker could possibly use this issue to cause a denial of service. (CVE-2018-12983)

    It was discovered that the PoDoFo library incorrectly handled memory allocation. If a user or application     were tricked into opening a crafted PDF file, an attacker could possibly use this issue to cause a denial     of service. This issue only affected Ubuntu 18.04 LTS, Ubuntu 20.04 LTS and Ubuntu 22.04 LTS.
    (CVE-2018-20797)

    It was discovered that the PoDoFo library did not properly validate memcpy arguments. If a user or     application were tricked into opening a crafted PDF file, an attacker could possibly use this issue to     cause a denial of service or execute arbitrary code. This issue only affected Ubuntu 14.04 LTS and Ubuntu     16.04 LTS. (CVE-2018-5308)

    It was discovered that the PoDoFo library incorrectly handled memory in the GetNextToken function, which     could lead to a buffer overflow. If a user or application were tricked into opening a crafted PDF file, an     attacker could possibly use this issue to cause a denial of service. This issue only affected Ubuntu 16.04     LTS. (CVE-2017-5886)

    It was discovered that the PoDoFo library could enter an infinite loop, which could lead to a stack     overflow. If a user or application were tricked into opening a crafted PDF file, an attacker could     possibly use this issue to cause a denial of service or execute arbitrary code. This issue only affected     Ubuntu 20.04 LTS and Ubuntu 22.04 LTS. (CVE-2018-8002, CVE-2020-18971, CVE-2021-30471, CVE-2021-30470)

    It was discovered that the PoDoFo library incorrectly handled memory allocation due to nInitialSize not     being validated. If a user or application were tricked into opening a crafted PDF file, an attacker could     possibly use this issue to cause a denial of service. This issue only affected Ubuntu 14.04 LTS, Ubuntu     16.04 LTS, Ubuntu 18.04 LTS and Ubuntu 20.04 LTS. (CVE-2019-10723)

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

The remote SUSE Linux SLES15 / openSUSE 15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2024:2137-1 advisory.

    - CVE-2019-9199: Fixed a NULL pointer dereference in podofoimpose (bsc#1127855)
    - CVE-2018-20797: Fixed an excessive memory allocation in PoDoFo:podofo_calloc (bsc#1127514)
    - CVE-2019-10723: Fixed a memory leak in PdfPagesTreeCache (bsc#1131544)

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

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

  - PoDoFo 0.9.6 has a heap-based buffer overflow in PdfString::ConvertUTF16toUTF8 in base/PdfString.cpp.
    (CVE-2019-9687)

  - A NULL pointer dereference vulnerability exists in the function PdfTranslator::setTarget() in
    pdftranslator.cpp of PoDoFo 0.9.6, while creating the PdfXObject, as demonstrated by podofoimpose. It
    allows an attacker to cause Denial of Service. (CVE-2018-19532)

  - An issue was discovered in crop_page in PoDoFo 0.9.6. For a crafted PDF document,
    pPage->GetObject()->GetDictionary().AddKey(PdfName("MediaBox"),var) can be problematic due to the function
    GetObject() being called for the pPage NULL pointer object. The value of pPage at this point is 0x0, which
    causes a NULL pointer dereference. (CVE-2018-20751)

  - An issue was discovered in PoDoFo 0.9.6. There is an attempted excessive memory allocation in
    PoDoFo::podofo_calloc in base/PdfMemoryManagement.cpp when called from
    PoDoFo::PdfPredictorDecoder::PdfPredictorDecoder in base/PdfFiltersPrivate.cpp. (CVE-2018-20797)

  - PoDoFo::Impose::PdfTranslator::setSource() in pdftranslator.cpp in PoDoFo 0.9.6 has a NULL pointer
    dereference that can (for example) be triggered by sending a crafted PDF file to the podofoimpose binary.
    It allows an attacker to cause Denial of Service (Segmentation fault) or possibly have unspecified other
    impact. (CVE-2019-9199)
