Security Bulletin
This security bulletin contains information about 4 vulnerabilities.
1) Resource exhaustion
EUVDB-ID: #VU12620
Risk: Low
CVSSv4.0: 1 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2017-11625
CWE-ID:
CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to cause DoS condition on the target system.
The weakness exists in the QPDF::resolveObjectsInStream function in QPDF.cc due to infinite loop. A remote attacker can trick the victim into opening a specially crafted file, trigger stack consumption and cause the service to crash.
Install updates from vendor's repository.

No. We are not aware of malware exploiting this vulnerability.
2) Resource exhaustion
EUVDB-ID: #VU12619
Risk: Low
CVSSv4.0: 1 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2017-11624
CWE-ID:
CWE-400 - Resource exhaustion
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to cause DoS condition on the target system.
The weakness exists in the QPDFTokenizer::resolveLiteral function in QPDFTokenizer.cc due to infinite loop after two consecutive calls to QPDFObjectHandle::parseInterna. A remote attacker can trick the victim into opening a specially crafted file, trigger stack consumption and cause the service to crash.

3) Resource exhaustion
EUVDB-ID: #VU12623
Risk: Low
CVSSv4.0: 1 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2017-12595
CWE-ID:
CWE-400 - Resource exhaustion
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to cause DoS condition on the target system.
The weakness exists in QPDFObjectHandle::parseInternal in libqpdf/QPDFObjectHandle.cc due to the tokenizer is recursive for arrays and dictionaries. A remote attacker can trick the victim into opening a specially crafted PDF document with a deep data structure, trigger stack consumption and cause the service to crash.

4) Resource exhaustion
EUVDB-ID: #VU12631
Risk: Low
CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2018-9918
CWE-ID:
CWE-400 - Resource exhaustion
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to cause DoS condition on the target system.
The weakness exists in the QPDFObjectHandle and QPDF_Dictionary classes due to mishandling certain "expected dictionary key but found non-name object" cases because nesting in direct objects is not restricted. A remote attacker can trigger stack exhaustion and cause the service to crash.
