xorg-x11-server: xorg-x11-server-Xwayland: xorg-x11-server: out-of-bounds heap write in DRI2 DRIGetBuffers/DRIGetBuffersWithFormat

An out-of-bounds write flaw was found in the X.Org X server and Xwayland in DRIGetBuffers/DRIGetBuffersWithFormat. A client that requests multiple DRI2BufferBackLeft attachments and one DRI2BufferFrontLeft can trigger an out-of-bounds heap write. This may be used to crash the server, or for...

CVE-2026-57255

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-2026-57251

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-2026-57250

When the application opens a PDF and JavaScript resets the form fields, the script re-enters the interface. The underlying native object is damaged, but the application does not perform validation. The function call on the damaged object leads to the application crashing...

CVE-2026-57240

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-2026-13128

Embedding JavaScript within a PDF file will cause the page to be deleted. Subsequent scripts will continue to access the relevant properties of the document view, eventually leading to the crash of the application...

CVE-2026-56002 libXfont2 PCF Font Parsing Heap Buffer Overflow

A heap bufferflow in pcfReadFont due to missing glyph bounds checking in libXfont2 before 2.0.8 allows attackers authenticated as X client to execute code within the X server...

EUVD-2026-42187

The embedded JavaScript in the PDF deleted the pages, making the object invalid. The application attempted to perform a write operation on the invalid pop-up annotations, resulting in the program crashing...

CVE-2026-13127

The application opens the PDF file. JavaScript then rewrites the document to modify the page structure, resulting in the invalidation of the page objects. However, the thumbnails still use the invalid page objects, ultimately causing the application to crash...

CVE-2026-57238

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...

EUVD-2026-42181

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...

EUVD-2026-42180

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...

EUVD-2026-42179

The application opens the PDF, and JavaScript modifies the form. However, the related objects on the page lack complete lifecycle management and null value validation; when the page state changes, the application continuously dereferences invalid objects, eventually leading to a crash...

EUVD-2026-42205

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-2026-57251

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-2026-57256 Foxit Editor/Reader List Box Format Use-After-Free Vulnerability

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...
