Description
This security bulletin contains information about 5 vulnerabilities.
1) NULL pointer dereference (CVE-ID: CVE-2017-5854)
CWE-ID: CWE-476 - NULL Pointer Dereference
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
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 file.
2) NULL pointer dereference (CVE-ID: CVE-2017-5855)
CWE-ID: CWE-476 - NULL Pointer Dereference
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
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 file.
3) Heap-based buffer overflow (CVE-ID: CVE-2017-5886)
CWE-ID: CWE-122 - Heap-based Buffer Overflow
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in Heap-based buffer overflow in the PoDoFo::PdfTokenizer::GetNextToken function in PdfTokenizer.cpp in PoDoFo 0.9.4. A remote attacker can use a crafted file. to trigger heap-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
4) Infinite loop (CVE-ID: CVE-2017-5852)
CWE-ID: CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.
The PoDoFo::PdfPage::GetInheritedKeyFromObject function in base/PdfVariant.cpp in PoDoFo 0.9.4 allows remote attackers to cause a denial of service (infinite loop) via a crafted file.
5) Integer overflow (CVE-ID: CVE-2017-5853)
CWE-ID: CWE-190 - Integer overflow
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber
The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.
Integer overflow in base/PdfParser.cpp in PoDoFo 0.9.4 allows remote attackers to have unspecified impact via a crafted file.
