Description

This security bulletin contains information about 9 vulnerabilities.


1) Improper input validation (CVE-ID: CVE-2017-14617)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote attacker to bypass security restrictions on the target system.

The vulnerability exists due to a floating point exception in the ImageStream class in Stream.cc. A remote attacker can supply specially crafted PDF files, bypass security restrictions and conduct further attacks.


2) NULL pointer derefenrece (CVE-ID: CVE-2017-14517)

CWE-ID: CWE-476 - NULL Pointer Dereference

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote attacker to cause a denial of service (DoS) conditions.

The vulnerability exists due to an error in  XRef::parseEntry() function in XRef.cc when processing PDF documents. A remote attacker can send a specially crafted document, trigger NULL pointer dereference and perform a denial of service attack.

Successful exploitation of the vulnerability may allow an attacker to cause application crash.


3) Division by zero (CVE-ID: CVE-2017-14518)

CWE-ID: CWE-369 - Divide By Zero

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:Clear


The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a floating point exception in the isImageInterpolationRequired() function in Splash.cc via a specially crafted PDF document. A remote attacker can perform a denial of service (DoS) attack.


4) Infinite loop (CVE-ID: CVE-2017-14519)

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:H/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote attacker to cause a denial of service (DoS) conditions.

The vulnerability exists due to an error in  Object::streamGetChar in Object.h after a repeating series of Gfx::display, Gfx::go, Gfx::execOp, Gfx::opShowText, and Gfx::doShowText calls when processing PDF documents. A remote attacker can send a specially crafted document, trigger infinite loop and perform a denial of service attack.

Successful exploitation of the vulnerability may allow an attacker to cause application crash.


5) Infinite loop (CVE-ID: CVE-2017-14929)

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

The weakness exists due to infinite loop in a call to Object::dictLookup() in Object.h after a repeating series of Gfx::display, Gfx::go, Gfx::execOp, Gfx::opFill, Gfx::doPatternFill, Gfx::doTilingPatternFill and Gfx::drawForm calls. A remote attacker can trigger memory corruption and cause the service to crash.

6) Division by zero (CVE-ID: CVE-2017-14520)

CWE-ID: CWE-369 - Divide By Zero

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:Clear


The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a floating point exception in Splash::scaleImageYuXd() in Splash.cc. A remote attacker can perform a denial of service (DoS) attack.



7) NULL pointer derefenrece (CVE-ID: CVE-2017-14975)

CWE-ID: CWE-476 - NULL Pointer Dereference

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote attacker to cause a denial of service (DoS) conditions.

The vulnerability exists due to an error in FoFiType1C::convertToType0 function in FoFiType1C.cc when processing documents. A remote attacker can send a specially crafted document, trigger NULL pointer dereference and perform a denial of service attack.

Successful exploitation of the vulnerability may allow an attacker to cause application crash.


8) Heap-based buffer overflow (CVE-ID: CVE-2017-14976)

CWE-ID: CWE-122 - Heap-based Buffer Overflow

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:Clear


The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to boundary error in FoFiType1C::convertToType0 function in FoFiType1C.cc when processing fonts in documents. A remote unauthenticated attacker can create a specially crafted document and trigger application crash.


9) NULL pointer derefenrece (CVE-ID: CVE-2017-14977)

CWE-ID: CWE-476 - NULL Pointer Dereference

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote attacker to cause a denial of service (DoS) conditions.

The vulnerability exists due to an error in FoFiTrueType::getCFFBlock function in FoFiTrueType.cc when processing documents. A remote attacker can send a specially crafted document, trigger NULL pointer dereference and perform a denial of service attack.

Successful exploitation of the vulnerability may allow an attacker to cause application crash.
