Description

This security bulletin contains information about 7 secuirty vulnerabilities.


1) Infinite loop (CVE-ID: CVE-2019-12973)

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

The vulnerability exists due to excessive iteration in the opj_t1_encode_cblks function of openjp2/t1.c in Open JPEG. A remote attacker can create a specially crafted .bmp file, pass it to the affected application and perform denial of service (DoS) attack.


2) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2019-14811)

The vulnerability allows a remote attacker to bypass implemented security restrictions.

The vulnerability exists due to unrestricted access to .forceput in .pdf_hook_DSC_Creator. A remote attacker can create a specially crafted PDF file, trick the victim to open it and gain access to arbitrary files on the system.


3) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2019-14812)

The vulnerability allows a remote attacker to bypass implemented security restrictions.

The vulnerability exists due to unrestricted access to .forceput in setuserparams. A remote attacker can create a specially crafted PDF file, trick the victim to open it and gain access to arbitrary files on the system.


4) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2019-14813)

The vulnerability allows a remote attacker to bypass implemented security restrictions.

The vulnerability exists due to unrestricted access to .forceput in setuserparams. A remote attacker can create a specially crafted PDF file, trick the victim to open it and gain access to arbitrary files on the system.


5) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2019-14817)

The vulnerability allows a remote attacker to bypass implemented security restrictions.

The vulnerability exists due to unrestricted access to .forceput in setuserparams. A remote attacker can create a specially crafted PDF file, trick the victim to open it and gain access to arbitrary files on the system.


6) Exposed dangerous method or function (CVE-ID: CVE-2019-3835)

The vulnerability allows a remote attacker to bypass certain security restrictions.
The vulnerability exists due presence of superexec operator within the internal dictionary. A remote attacker can create a specially crafted PDF file, trick the victim into opening, bypass system restrictions of the dSAFER sandbox and access files on the system.

7) Buffer overflow (CVE-ID: CVE-2019-3839)

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

The vulnerability exists due to a boundary error when processing Postsccript files within the GPL PostScript/PDF interpreter. A remote attacker can create a specially crafted Postscript document, trick the victim into opening it, trigger memory corruption and execute arbitrary code on the target system.

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