CVE-2018-11255

An issue was discovered in PoDoFo 0.9.5. The function PdfPage::GetPageNumber() in PdfPage.cpp in PoDoFo 0.9.5 allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a crafted PDF document.

The podofo package has been updated to fix several security issues.

These are all security issues fixed in the libpodofo-devel-0.9.7-2.2 package on the GA media of openSUSE Tumbleweed.

These are all security issues fixed in the libpodofo-0_10-devel-0.10.5-1.1 package on the GA media of openSUSE Tumbleweed.

This update for podofo fixes the following issues:

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.
