Description

This security bulletin contains information about 4 vulnerabilities.


1) Resource exhaustion (CVE-ID: CVE-2017-11624)

CWE-ID: CWE-400 - Resource exhaustion

CVSSv4: 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


The 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.

2) Resource exhaustion (CVE-ID: CVE-2017-11625)

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

CVSSv4: 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


The 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.

3) Resource exhaustion (CVE-ID: CVE-2017-11626)

CWE-ID: CWE-400 - Resource exhaustion

CVSSv4: 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


The 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 four 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.

4) Resource exhaustion (CVE-ID: CVE-2017-11627)

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

CVSSv4: 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


The vulnerability allows a remote attacker to cause DoS condition on the target system.

The weakness exists in the PointerHolder function in PointerHolder.hh 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.
