Description
This security bulletin contains information about 9 secuirty vulnerabilities.
1) Division by zero (CVE-ID: CVE-2023-2662)
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)
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)
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)
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)
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)
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)
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)
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)
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.
