CVE-2026-56403
libexpat before 2.8.2 has an integer overflow in storeAtts.
Publication Mise à jourCVE-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 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-2025-66382
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.
Publication Mise à jourCVE-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.
Publication Mise à jourCVE-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).
Publication Mise à jourCVE-2024-45491
An issue was discovered in libexpat before 2.6.3. dtdCopy in xmlparse.c can have an integer overflow for nDefaultAtts on 32-bit platforms (where UINT_MAX equals SIZE_MAX).
Publication Mise à jourCVE-2024-45490
An issue was discovered in libexpat before 2.6.3. xmlparse.c does not reject a negative length for XML_ParseBuffer.
Publication Mise à jourCVE-2024-28757
libexpat through 2.6.1 allows an XML Entity Expansion attack when there is isolated use of external parsers (created via XML_ExternalEntityParserCreate).
