SB2020120906 - Multiple vulnerabilities in Foxit Reader and PhantomPDF

Description

This security bulletin contains information about 8 secuirty vulnerabilities.

1) Out-of-bounds write (CVE-ID: CVE-2020-27860)

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a boundary error while processing certain XFA templates. A remote attacker can create a specially crafted PDF file, trick the victim into opening it using the affected software, trigger out-of-bounds write and execute arbitrary code on the target system.

2) Spoofing attack (CVE-ID: N/A)

The vulnerability allows a remote attacker to perform an Evil Annotation Attack.

The vulnerability exists due to incorrect processing of user-supplied data when validating certain certified PDF files whose visible content was significantly altered. A remote attacker can spoof contents of the PDF file.

3) Type Confusion (CVE-ID: CVE-2020-13547)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a type confusion error, when an incorrect argument was passed to the app.media.openPlayer function defined in PDF JavaScript API. A remote attacker can create specially crafted PDF file, trick the victim into opening it, trigger a type confusion error and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

4) Use-after-free (CVE-ID: CVE-2020-13548)

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a use-after-free error when processing PDF files. A remote attacker can create a specially crafted PDF file, trick the victim into opening it, trigger a use-after-free error and execute arbitrary code on the system.

Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.

5) Use-after-free (CVE-ID: CVE-2020-13557)

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a use-after-free error when processing PDF files. A remote attacker can create a specially crafted PDF file, trick the victim into opening it, trigger a use-after-free error and execute arbitrary code on the system.

Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.

6) Use-after-free (CVE-ID: CVE-2020-13560)

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a use-after-free error when processing PDF files. A remote attacker can create a specially crafted PDF file, trick the victim into opening it, trigger a use-after-free error and execute arbitrary code on the system.

Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.

7) Use-after-free (CVE-ID: CVE-2020-13570)

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a use-after-free error when processing PDF files. A remote attacker can create a specially crafted PDF file, trick the victim into opening it, trigger a use-after-free error and execute arbitrary code on the system.

Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.

8) Improper Validation of Array Index (CVE-ID: CVE-2020-28203)

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

The vulnerability exists due to array overflow as the illegal value in the /Size entry causes an error in initializing the array size for storing the compression object streams, and an object number which is larger than the initialization value is used as the array index while parsing the cross-reference streams. A remote attacker can create a specially crafted PDF file, trick the victim into opening it and crash the application.
