Vulnerabilidades do Foxit Software Inc. Foxit PDF Reader

A heap-based out-of-bounds write vulnerability exists in Foxit PDF Editor/Reader’s PRC parser due to insufficient validation of vertex indices in triangular fan texture meshes. Successful exploitation could result in memory corruption and an application crash.

A use-after-free vulnerability exists in Foxit PDF Editor/Reader’s handling of PDF annotations. Reentrant annotation deletion triggered by embedded JavaScript can cause the application to access an annotation object after it has been released, resulting in a use-after-free condition and application crash.

Foxit PDF Editor/Reader does not perform sufficient verification of the JPEG2000 image metadata in the PDF file, which leads to out-of-bounds write in the heap buffer during decoding, potentially causing the program to crash and introducing the risk of arbitrary code execution.

A vulnerability in Foxit PDF Editor/Reader’s update mechanism allows an update package to be replaced between download and high-privilege extraction due to insufficient file locking and integrity validation. This could enable local attackers to execute arbitrary code with elevated privileges.

A vulnerability in Foxit PDF Editor/Reader’s update mechanism allows man-in-the-middle attackers to bypass certificate validation and package integrity checks, potentially enabling arbitrary code execution with system privileges.

A use-after-free vulnerability exists in Foxit PDF Editor/Reader’s handling of malformed PDF form fields. Improper validation during field-name traversal may cause the application to access a released object, resulting in an application crash.

A use-after-free vulnerability exists in Foxit PDF Editor/Reader’s handling of PDF form fields. Embedded JavaScript may access form-field references after the corresponding fields have been released, resulting in an application crash.

A use-after-free vulnerability exists in Foxit PDF Editor/Reader’s PDF page-tree handling. A specially crafted PDF can trigger page-structure changes during rendering, causing the application to access released page objects and resulting in memory corruption and an application crash.

A heap-based out-of-bounds write vulnerability exists in Foxit PDF Editor/Reader’s rendering of Circle annotations with malformed Cloudy appearance streams in specially crafted PDF files. Insufficient validation of the appearance geometry can result in memory corruption and application crashes.

A local privilege escalation vulnerability exists in the updater of Foxit PDF Editor/Reader due to unsafe loading of dynamic-link libraries from a user-writable directory during high-privilege operations. A local attacker could exploit this issue to execute code with elevated privileges.

A path traversal vulnerability exists in Foxit PDF Editor/Reader's handling of embedded PDF resources. Insufficient validation of resource file paths may allow files to be written outside their intended locations, potentially enabling arbitrary code execution.

A use-after-free vulnerability exists in Foxit PDF Editor/Reader’s handling of JavaScript array objects. A specially crafted PDF may cause the application to access a released object during array processing, potentially resulting in application crashes or arbitrary code execution.

Foxit PDF Editor/Reader failed to validate the directory traversal path in the attachment file name, resulting in malicious attachments being able to be written to directories outside the expected secure area when the PDF is opened.

Foxit PDF Editor/Reader's FileOpen plugin did not adequately validate certain encryption metadata in specially crafted PDF files. This could leave an internal pointer in an invalid state, resulting in chained read and write access violations and potentially enabling arbitrary code execution.

When opening a specially crafted PDF, Foxit PDF Editor/Reader executes scripts that modify annotation rich-text attributes containing malformed font data. During subsequent annotation appearance reconstruction, it accesses an object after it has been released, resulting in a use-after-free condition and an application crash.

When processing a specially crafted PDF, Foxit PDF Editor/Reader may perform reentrant zoom and layout operations through page- and annotation-related JavaScript actions. This can cause the application to access page objects after they have been released, resulting in a use-after-free condition and an application crash.

When processing a specially crafted PDF file, Foxit PDF Editor/Reader may encounter a reentrant execution condition involving JavaScript triggered by page-visibility events. This can cause the application to access a released page-view object while calculating annotation boundaries, resulting in an invalid memory read and application crash.

When rendering the page image, Foxit PDF Editor/Reader fails to perform validation on image objects whose optional content attributes are malformed. As a result, the program may access an already-freed internal data structure, triggering a crash due to UAF.

Foxit PDF Editor/Reader’s U3D/GIF texture decoding path contained insufficient validation of image dimensions and related size information. Under certain conditions, this could lead to an incorrectly sized memory allocation and a subsequent out-of-bounds write during pixel processing, potentially resulting in remote code execution.
