CVE-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.
Publication Mise à jourCVE-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).
Publication Mise à jourCVE-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,
Publication Mise à jourCVE-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.
Publication Mise à jourCVE-2026-41080
libexpat before 2.8.0 uses insufficient entropy, and thus hash flooding can occur via a crafted XML document.
Publication Mise à jourGrassroots DICOM Missing release of memory after effective lifetime
A memory leak exists in the Grassroots DICOM library (GDCM). The bug occurs when parsing malformed DICOM files with non-standard VR types in file meta information. The vulnerability leads to vast memory allocations and resource depletion, triggering a denial-of-service condition. A maliciously crafted file can fill the heap in a single read operation without properly releasing it.
Publication Mise à jourCVE-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.
Publication Mise à jourCVE-2026-32777
libexpat before 2.7.5 allows an infinite loop while parsing DTD content.
Publication Mise à jourCVE-2026-32776
libexpat before 2.7.5 allows a NULL pointer dereference with empty external parameter entity content.
Publication Mise à jourCVE-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.
Publication Mise à jourCVE-2026-24515
In libexpat before 2.7.4, XML_ExternalEntityParserCreate does not copy unknown encoding handler user data.
Publication Mise à jourCVE-2025-53619
An out-of-bounds read vulnerability exists in the JPEGBITSCodec::InternalCode functionality of Grassroot DICOM 3.024. A specially crafted DICOM file can lead to an information leak. An attacker can provide a malicious file to trigger this vulnerability.The function `null_convert` is called based of the value of the malicious DICOM file specifying the intended interpretation of the image pixel data

An attacker can provide a malicious file to trigger this vulnerability.The function `grayscale_convert` is called based of the value of the malicious DICOM file specifying the intended interpretation of the image pixel data
Publication Mise à jourCVE-2025-52582
An out-of-bounds read vulnerability exists in the Overlay::GrabOverlayFromPixelData functionality of Grassroot DICOM 3.024. A specially crafted DICOM file can lead to an information leak. An attacker can provide a malicious file to trigger this vulnerability.
Publication Mise à jourCVE-2025-48429
An out-of-bounds read vulnerability exists in the RLECodec::DecodeByStreams functionality of Grassroot DICOM 3.024. A specially crafted DICOM file can lead to leaking heap data. An attacker can provide a malicious file to trigger this vulnerability.
Publication Mise à jourGrassroots DICOM (GDCM) Out-of-bounds Write
An out-of-bounds write vulnerability exists in the Grassroots DICOM library (GDCM). The issue is triggered during parsing of a malformed DICOM file containing encapsulated PixelData fragments (compressed image data stored as multiple fragments). This vulnerability leads to a segmentation fault caused by an out-of-bounds memory access due to unsigned integer underflow in buffer indexing. It is exploitable via file input, simply opening a crafted malicious DICOM file is sufficient to trigger the crash, resulting in a denial-of-service condition.
Publication Mise à jourCVE-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.
Publication Mise à jourCVE-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.
Publication Mise à jourLibexpat: 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.
