libpodofo vulnerabilities
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 22.04 LTS
- Ubuntu 20.04 LTS
- Ubuntu 18.04 LTS
- Ubuntu 16.04 LTS
- Ubuntu 14.04 LTS
Summary:
Several security issues were fixed in PoDoFo.
Software Description:
- libpodofo: PDF manipulation library
Details:
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)
