Foxit Reader <= 5.4.5.0114 Plugin URL Processing Buffer Overflow

Foxit Reader versions through 5.4.5.0114, including the bundled Foxit Reader Plugin 2.2.1.530, contains a stack-based buffer overflow vulnerability in the npFoxitReaderPlugin.dll module. When a PDF file is loaded from a remote host, an overly long query string in the URL can overflow a buffer, allowing remote attackers to execute arbitrary code.

Stack-based buffer overflow in Foxit Reader 3.0 before Build 1506, including 1120 and 1301, allows remote attackers to execute arbitrary code via a long (1) relative path or (2) absolute path in the filename argument in an action, as demonstrated by the "Open/Execute a file" action.

Foxit PDF Reader PDF Parsing Heap-Based Buffer Overflow Remote Code Execution Vulnerability

A heap-based buffer overflow vulnerability exists in the PDF parsing of Foxit PDF Reader when processing specially crafted JBIG2 data. An integer overflow in the calculation of the image buffer size may occur, potentially allowing a remote attacker to execute arbitrary code.

Foxit PDF Reader 3D Annotation Out-of-Bounds Memory Access Vulnerability

A memory corruption vulnerability exists in the 3D annotation handling of Foxit PDF Reader due to insufficient bounds checking when parsing U3D data. When opening a PDF file containing malformed or specially crafted PRC content, out-of-bounds memory access may occur, resulting in memory corruption.

Foxit PDF Reader 3D Annotation Out-of-Bounds Memory Access Vulnerability

A memory corruption vulnerability exists in the 3D annotation handling of Foxit PDF Reader due to insufficient bounds checking when parsing PRC data. When opening a PDF file containing malformed or specially crafted PRC content, out-of-bounds memory access may occur, resulting in memory corruption.

Foxit PDF Reader Annotation Use-After-Free Remote Code Execution Vulnerability

A use-after-free vulnerability exists in the annotation handling of Foxit PDF Reader before 2025.2.1, 14.0.1, and 13.2.1 on Windows and MacOS. When opening a PDF containing specially crafted JavaScript, a pointer to memory that has already been freed may be accessed or dereferenced, potentially allowing a remote attacker to execute arbitrary code.

Foxit PDF Reader Update Service Incorrect Permission Assignment Local Privilege Escalation Vulnerability

A local privilege escalation vulnerability exists in the Foxit PDF Reader/Editor Update Service. During plugin installation, incorrect file system permissions are assigned to resources used by the update service. A local attacker with low privileges could modify or replace these resources, which are later executed by the service, resulting in execution of arbitrary code with SYSTEM privileges.

A use-after-free vulnerability exists in the way Foxit Reader 12.1.2.15356 handles a signature field. A specially crafted Javascript code inside a malicious PDF document can trigger reuse of a previously freed object, which can lead to memory corruption and result in arbitrary code execution. An attacker needs to trick the user into opening the malicious file to trigger this vulnerability. Exploitation is also possible if a user visits a specially crafted, malicious site if the browser plugin extension is enabled.

A use-after-free vulnerability exists in the way Foxit Reader 2024.1.0.23997 handles a Barcode widget. A specially crafted JavaScript code inside a malicious PDF document can trigger reuse of a previously freed object, which can lead to memory corruption and result in arbitrary code execution. An attacker needs to trick the user into opening the malicious file to trigger this vulnerability. Exploitation is also possible if a user visits a specially crafted, malicious site if the browser plugin extension is enabled.

A memory corruption vulnerability exists in Foxit Reader 2025.1.0.27937 due to the use of an uninitialized pointer. A specially crafted Javascript code inside a malicious PDF document can trigger this vulnerability, which can lead to memory corruption and result in arbitrary code execution. An attacker needs to trick the user into opening the malicious file to trigger this vulnerability. Exploitation is also possible if a user visits a specially crafted, malicious site if the browser plugin extension is enabled.

Foxit PDF SDK For Web through 7.5.0 allows XSS. There is arbitrary JavaScript code execution in the browser if a victim uploads a malicious PDF document containing embedded JavaScript code that abuses app.alert (in the Acrobat JavaScript API).
