Description

This security bulletin contains information about 9 vulnerabilities.


1) Division by zero (CVE-ID: CVE-2023-2662)

CWE-ID: CWE-369 - Divide By Zero

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:Green


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

The vulnerability exists due to a divide by zero error when processing PDF files. A remote attacker can pass a specially crafted PDF file to the application, trigger a division by zero error and crash the application.

2) Infinite loop (CVE-ID: CVE-2018-7453)

CWE-ID: CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')

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:Green


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

Infinite recursion in AcroForm::scanField in AcroForm.cc in xpdf 4.00 allows attackers to launch denial of service via a specific pdf file due to lack of loop checking, as demonstrated by pdftohtml.


3) Input validation error (CVE-ID: CVE-2018-16369)

CWE-ID: CWE-20 - Improper input validation

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:Green


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

The vulnerability exists due to insufficient validation of user-supplied input. A remote attacker can cause a denial of service (stack consumption) via a crafted pdf file, related to AcroForm::scanField, as demonstrated by pdftohtml.


4) Input validation error (CVE-ID: CVE-2022-36561)

CWE-ID: CWE-20 - Improper input validation

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:Green


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

The vulnerability exists due to a segmentation violation in the component /xpdf/AcroForm.cc:538. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.


5) Resource exhaustion (CVE-ID: CVE-2022-41844)

CWE-ID: CWE-400 - Resource exhaustion

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:Green


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

The vulnerability exists due to application does not properly control consumption of internal resources in XRef::fetch(int, int, Object*, int) in xpdf/XRef.cc. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.


6) Infinite loop (CVE-ID: CVE-2023-2663)

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:Green


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

The vulnerability exists due to infinite loop. A remote attacker can consume all available system resources and cause denial of service conditions.


7) Infinite loop (CVE-ID: CVE-2023-2664)

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:Green


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

The vulnerability exists due to infinite loop. A remote attacker can consume all available system resources and cause denial of service conditions.


8) Division by zero (CVE-ID: CVE-2023-3044)

CWE-ID: CWE-369 - Divide By Zero

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:Green


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

The vulnerability exists due to a divide by zero error when processing PDF files. A remote attacker can pass a specially crafted PDF file to the application, trigger a division by zero error and crash the application.


9) Deadlock (CVE-ID: CVE-2023-3436)

CWE-ID: CWE-833 - Deadlock

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:Green


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

The vulnerability exists due to a deadlock on a PDF object stream whose "Length" field is itself in another object stream. A remote attacker can pass specially crafted PDF files to the application and perform a denial of service (DoS) attack.
