CVE-2026-15053: Memory Allocation with Excessive Size Value

Tanium addressed a denial of service vulnerability in Tanium Server...

CVE-2026-57260: Out-of-bounds Write

The application opened a PDF file containing an abnormal Unity 3D object. During parsing, the application incorrectly resolved a portion of the abnormal object as a pointer and used it as a valid address, ultimately causing the application to crash...

CVE-2026-57259: Improper Restriction of XML External Entity Reference

The input file does not need to be strictly in a structurally valid PDF format. Instead, after reviewing the content, the original document disguised as a PDF will be sent to the parser. Malicious documents will construct malicious external entities that, through the protocol, point to local path...

CVE-2026-57258: Out-of-bounds Read

The PRC file header parsing logic trusts the constructed file structure description information, assumes that the underlying array contains elements and reads them, leading to out-of-bounds reads and application crashes...

CVE-2026-57257: Out-of-bounds Read

During the PRC parsing stage, there is a lack of boundary verification for the PRC entity index, which leads to an out-of-bounds read of the entity array. As a result, the application crashes...

CVE-2026-57256: Use After Free

When the application opens a PDF and executes JavaScript, it performs abnormal operations on the list box field, and this operation is repeated after the form is reset. During this process, the application failed to adequately verify the validity of the form objects and their internal dictionary...

CVE-2026-57255: Out-of-bounds Read

The application opens a PDF containing an abnormal color space whose attributes reference a valid but semantically malformed function. The function's output is not validated; when subsequently read, it produces an illegal pointer that accesses an out-of-bounds region, crashing the application...

CVE-2026-57254: Access of Resource Using Incompatible Type

There is an abnormal annotation within the PDF that is referenced by other objects. When the application parses the PDF, it fails to perform proper type checking, ultimately causing the application to crash...

CVE-2026-57253: Out-of-bounds Read

An abnormal image object causes the renderer to enter the wrong processing branch. When converting the scan lines, an invalid image buffer pointer is used, resulting in the application crashing...

CVE-2026-57252: Use After Free

When the application opens a PDF file, during the process of JavaScript deleting pages and removing attachment annotations, it will cause the attachment panel to continue accessing invalid pointers, eventually leading to the application crashing...

CVE-2026-57251: Improper Validation of Array Index

The application opens a PDF, but the cloud-like appearance of the construction process lacks proper setting of an upper limit and consistency checks. Out-of-bounds access to the underlying array is exposed, ultimately leading to a crash of the application...

CVE-2026-57249: Use After Free

After the application opened the PDF file, the script first reset the annotation status, then triggered the reset form event by additional action. During the re-entry process, the application access invalid objects and crashed...

CVE-2026-57248: Release of Invalid Pointer or Reference

When the application opens a PDF file and JavaScript writes annotation attributes, there is a lack of sufficient object type and argument checks. As a result, due to the damage to the internal structure of the annotations, it causes the application to crash during subsequent release...

CVE-2026-57246: Buffer Copy without Checking Size of Input

When dealing with abnormally constructed objects, there is a lack of argument validation; JavaScript triggers signature verification, but the signature plugin does not perform validation when copying the abnormal string, causing the application to crash...

CVE-2026-57244: Use After Free

After JavaScript resetting the form, the synchronization process lacks re-entry protection and object lifecycle verification, resulting in the failure of the control pointer during the traversal process. After the pointer fails, it still continues to dereference, causing the application to crash...

CVE-2026-57243: Out-of-bounds Read

During the process of page opening and form formatting, a JavaScript reentrancy results in an inconsistent document status. Subsequently, with outdated page information, the application attempts to access invalid addresses, causing the application to crash...

CVE-2026-57241: Out-of-bounds Read

The application opens the PDF, and JavaScript performs operations on the page and the document, causing the page-related objects within the application to lose synchronization; however, the renderer still trusts the outdated page count, and eventually the application crashes due to out-of-bounds...

CVE-2026-57240: Use After Free

When the application opens a PDF file and JavaScript deletes the PDF fields, the subsequent logic still uses the old field pointers, resulting in invalid pointer references and causing the application to crash...

CVE-2026-57239: Uncontrolled Search Path Element

The user-controllable executable files will be directly executed by high-privilege processes, allowing low-privilege users to have the opportunity to elevate their privileges to NT AUTHORITY\SYSTEM...

CVE-2026-57238: Use After Free

After the application opened the PDF, JavaScript deleted the form field object. Subsequently, it attempted to access the invalid object, which caused the application to crash...
