Description
This security bulletin contains information about 1 vulnerability.
1) Resource exhaustion (CVE-ID: CVE-2018-9918)
CWE-ID: CWE-400 - Resource exhaustion
CVSSv4: 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
The 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.
