Description

This security bulletin contains information about 1 vulnerability.


1) Infinite loop (CVE-ID: CVE-2018-11797)

CWE-ID: CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')

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 vulnerability allows an unauthenticated, remote attacker to cause a denial of service (DoS) condition on a target system.

The vulnerability exists in the Apache PDFBox parser due to improper processing of PDF files when parsing the page tree. A remote attacker can trick the victim into opening a PDF file that submits malicious input to the targeted system, trigger an infinite loop condition, which could lead to an out-of-memory exception and result in a DoS condition.
