A remote attacker can create a specially crafted PDF file, trick the victim into opening it and compromise vulnerable system.

Successful exploitation of the vulnerability may allow an attacker to execute arbitrary code on the target system with privileges of the current user.

3) Use-after-free (CVE-ID: N/A)

CWE-ID: CWE-416 - Use After Free

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

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

Successful exploitation of the vulnerability may allow an attacker to execute arbitrary code on the target system with privileges of the current user.

4) Out-of-bound read (CVE-ID: N/A)

CWE-ID: CWE-125 - Out-of-bounds read

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

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

The vulnerability exists due to boundary error, 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 and gain access to potentially sensitive information.

Successful exploitation of the vulnerability may allow an attacker to gain access to potentially sensitive information.

5) Out-of-bounds write (CVE-ID: CVE-2017-10994)

CWE-ID: CWE-787 - Out-of-bounds write

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, trigger out-of-bounds write and compromise vulnerable system.

Successful exploitation of the vulnerability may allow an attacker to execute arbitrary code on the target system with privileges of the current user.

6) Improper initialization (CVE-ID: N/A)

CWE-ID: CWE-665 - Improper Initialization

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 perform a denial of service (DoS) attack.

The vulnerability exists due to improper initialization of variables before their usage when processing PDF files. A remote attacker cat create a specially crafted PDF file, trick the victim into opening it and crash the application.
