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.

Affected: Ubuntu:Pro:14.04:LTS: libpodofo, Ubuntu:Pro:16.04:LTS: libpodofo, Ubuntu:Pro:18.04:LTS: libpodofo, Ubuntu:Pro:20.04:LTS: libpodofo, Ubuntu:Pro:22.04:LTS: libpodofo

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)
