Heap-based buffer overflow in the PoDoFo::PdfTokenizer::GetNextToken function in PdfTokenizer.cpp in PoDoFo 0.9.4 allows remote attackers to have unspecified impact via a crafted file.

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.

Several heap-based buffer overflows, integer overflows and NULL pointer dereferences have been discovered in libpodofo, a library for manipulating PDF files, that allow remote attackers to cause a denial of service (application crash) or other unspecified impact via a crafted PDF document.

For Debian 7 'Wheezy', these problems have been fixed in version 0.9.0-1.1+deb7u1.

We recommend that you upgrade your libpodofo packages.
