 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)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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