Description

This security bulletin contains information about 13 secuirty vulnerabilities.


1) Out-of-bounds read (CVE-ID: CVE-2020-3804)

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to a boundary condition when processing PDF files. A remote attacker can create a specially crafted PDF file, trick the victim into opening it, trigger out-of-bounds read error and read contents of memory on the system.


2) Out-of-bounds read (CVE-ID: CVE-2020-3806)

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to a boundary condition when processing PDF files. A remote attacker can create a specially crafted PDF file, trick the victim into opening it, trigger out-of-bounds read error and read contents of memory on the system.


3) Out-of-bounds write (CVE-ID: CVE-2020-3795)

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a boundary error when processing PDF files. 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.


4) Stack-based buffer overflow (CVE-ID: CVE-2020-3799)

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

The vulnerability exists due to a boundary error when processing PDF files. A remote unauthenticated attacker can create a specially crafted PDF file, trick the victim into opening it, trigger stack-based buffer overflow and execute arbitrary code on the target system.

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


5) Use-after-free (CVE-ID: CVE-2020-3792)

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

The vulnerability exists due to a boundary error when processing PDF files. A remote unauthenticated 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 target system.

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


6) Use-after-free (CVE-ID: CVE-2020-3793)

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

The vulnerability exists due to a boundary error when processing PDF files. A remote unauthenticated 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 target system.

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


7) Use-after-free (CVE-ID: CVE-2020-3801)

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

The vulnerability exists due to a boundary error when processing PDF files. A remote unauthenticated 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 target system.

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


8) Use-after-free (CVE-ID: CVE-2020-3802)

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

The vulnerability exists due to a boundary error when processing form objects within XFA templates in PDF files. A remote unauthenticated 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 target system.

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


9) Use-after-free (CVE-ID: CVE-2020-3805)

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

The vulnerability exists due to a boundary error when processing PDF files. A remote unauthenticated 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 target system.

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


10) Memory leak (CVE-ID: CVE-2020-3800)

The vulnerability allows a remote attacker to gain access to sensitive information.

The vulnerability exists due memory leak when processing PDF files. A remote attacker can create a specially crafted PDF file, trick the victim into opening it and gain access to sensitive information.


11) Buffer overflow (CVE-ID: CVE-2020-3807)

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

The vulnerability exists due to a boundary error when processing PDF files. A remote unauthenticated attacker can create a specially crafted PDF file, trick the victim into opening it, trigger a buffer overflow and execute arbitrary code on the target system.

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


12) Memory corruption (CVE-ID: CVE-2020-3797)

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

The vulnerability exists due to a boundary error when processing PDF files. A remote unauthenticated attacker can create a specially crafted PDF file, trick the victim into opening it, trigger a buffer overflow and execute arbitrary code on the target system.

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


13) Insecure DLL loading (CVE-ID: CVE-2020-3803)

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to the application loads DLL libraries in an insecure manner. A remote attacker can place a specially crafted .dll file on a remote SMB fileshare, trick the victim into opening a file, associated with the vulnerable application, and execute arbitrary code on victim's system.
