Description
This security bulletin contains information about 7 secuirty vulnerabilities.
1) Allocation of Resources Without Limits or Throttling (CVE-ID: CVE-2018-5783)
The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.
In PoDoFo 0.9.5, there is an uncontrolled memory allocation in the PoDoFo::PdfVecObjects::Reserve function (base/PdfVecObjects.h). Remote attackers could leverage this vulnerability to cause a denial of service via a crafted pdf file.
2) Uncontrolled Recursion (CVE-ID: CVE-2018-11254)
The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.
An issue was discovered in PoDoFo 0.9.5. There is an Excessive Recursion in the PdfPagesTree::GetPageNode() function of PdfPagesTree.cpp. Remote attackers could leverage this vulnerability to cause a denial of service through a crafted pdf file, a related issue to CVE-2017-8054.
3) NULL pointer dereference (CVE-ID: CVE-2018-11255)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error. A remote attacker can trigger denial of service conditions via a crafted PDF document.
4) NULL pointer dereference (CVE-ID: CVE-2018-11256)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error. A remote attacker can trigger denial of service conditions via a crafted PDF document.
5) Buffer overflow (CVE-ID: CVE-2018-12982)
The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.
Invalid memory read in the PoDoFo::PdfVariant::DelayedLoad() function in PdfVariant.h in PoDoFo 0.9.6-rc1 allows remote attackers to have denial-of-service impact via a crafted file.
6) Out-of-bounds read (CVE-ID: CVE-2018-14320)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition within the PdfEncoding::ParseToUnicode() function in PoDoFo library. A remote attacker can create a specially crafted file, trick the victim into opening it, trigger out-of-bounds read error and read contents of memory on the system.
7) NULL pointer dereference (CVE-ID: CVE-2018-19532)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error in the function PdfTranslator::setTarget() in pdftranslator.cpp of PoDoFo 0.9.6, while creating the PdfXObject, as demonstrated by podofoimpose. It allows an attacker to cause Denial of Service. A remote attacker can perform a denial of service (DoS) attack.
