CVE-2026-56403
libexpat before 2.8.2 has an integer overflow in storeAtts.
Publicación ActualizaciónCVE-2026-56132
In libexpat before 2.8.2, there is a heap-based buffer overflow in doProlog in xmlparse.c because scaffold backing array reallocation is mishandled when there is data-structure sharing across parsers.
Publicación ActualizaciónCVE-2026-56131
libexpat before 2.8.2 lacks handler call depth tracking for calls to XML_ResumeParser from within handlers in cases of a policy violation. Thus, a use-after-free can occur (similar to the CVE-2026-50219 situation).
Publicación ActualizaciónCVE-2026-50219
libexpat before 2.8.2 lacks handler call depth tracking for calls to XML_GetBuffer, XML_Parse, XML_ParseBuffer, XML_ParserFree, or XML_ParserReset from within handlers in cases of a policy violation. Thus, a use-after-free can occur,
Publicación ActualizaciónCVE-2026-45186
In libexpat before 2.8.1, the computational complexity of attribute name collision checks allows a denial of service via moderately sized crafted XML input.
Publicación ActualizaciónCVE-2026-41080
libexpat before 2.8.0 uses insufficient entropy, and thus hash flooding can occur via a crafted XML document.
Publicación ActualizaciónCVE-2026-32778
libexpat before 2.7.5 allows a NULL pointer dereference in the function setContext on retry after an earlier ouf-of-memory condition.
Publicación ActualizaciónCVE-2026-32777
libexpat before 2.7.5 allows an infinite loop while parsing DTD content.
Publicación ActualizaciónCVE-2026-32776
libexpat before 2.7.5 allows a NULL pointer dereference with empty external parameter entity content.
Publicación ActualizaciónCVE-2026-25210
In libexpat before 2.7.4, the doContent function does not properly determine the buffer size bufSize because there is no integer overflow check for tag buffer reallocation.
Publicación ActualizaciónCVE-2026-24515
In libexpat before 2.7.4, XML_ExternalEntityParserCreate does not copy unknown encoding handler user data.
Publicación ActualizaciónCVE-2025-66382
In libexpat through 2.7.3, a crafted file with an approximate size of 2 MiB can lead to dozens of seconds of processing time.
Publicación ActualizaciónCVE-2025-57108
Kitware VTK (Visualization Toolkit) through 9.5.0 contains a heap use-after-free vulnerability in vtkGLTFDocumentLoader. The vulnerability manifests during mesh object copy operations where vector members are accessed after the underlying memory has been freed, specifically when handling GLTF files with corrupted or invalid mesh reference structures.
Publicación ActualizaciónCVE-2025-57107
Kitware VTK (Visualization Toolkit) through 9.5.0 contains a heap buffer overflow vulnerability in vtkGLTFDocumentLoader. When processing specially crafted GLTF files, the copy constructor of Accessor objects fails to properly validate buffer boundaries before performing memory read operations.
Publicación ActualizaciónCVE-2025-57106
Kitware VTK (Visualization Toolkit) up to 9.5.0 is vulnerable to Buffer Overflow in vtkGLTFDocumentLoader. The vulnerability occurs in the BufferDataExtractionWorker template function when processing GLTF accessor data.
Publicación ActualizaciónCVE-2025-59375
libexpat in Expat before 2.7.2 allows attackers to trigger large dynamic memory allocations via a small document that is submitted for parsing.
Publicación ActualizaciónLibexpat: expat: improper restriction of xml entity expansion depth in libexpat
A stack overflow vulnerability exists in the libexpat library due to the way it handles recursive entity expansion in XML documents. When parsing an XML document with deeply nested entity references, libexpat can be forced to recurse indefinitely, exhausting the stack space and causing a crash. This issue could lead to denial of service (DoS) or, in some cases, exploitable memory corruption, depending on the environment and library usage.
Publicación ActualizaciónCVE-2024-50602
An issue was discovered in libexpat before 2.6.4. There is a crash within the XML_ResumeParser function because XML_StopParser can stop/suspend an unstarted parser.
Publicación ActualizaciónCVE-2024-45492
An issue was discovered in libexpat before 2.6.3. nextScaffoldPart in xmlparse.c can have an integer overflow for m_groupSize on 32-bit platforms (where UINT_MAX equals SIZE_MAX).
