CVE-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).
Publication Mise à jourCVE-2023-52426
libexpat through 2.5.0 allows recursive XML Entity Expansion if XML_DTD is undefined at compile time.
Publication Mise à jourCVE-2023-52425
libexpat through 2.5.0 allows a denial of service (resource consumption) because many full reparsings are required in the case of a large token for which multiple buffer fills are needed.
Publication Mise à jourCVE-2022-43680
In libexpat through 2.4.9, there is a use-after free caused by overeager destruction of a shared DTD in XML_ExternalEntityParserCreate in out-of-memory situations.
Publication Mise à jourCVE-2022-40674
libexpat before 2.4.9 has a use-after-free in the doContent function in xmlparse.c.

Publication Mise à jourCVE-2022-25313
In Expat (aka libexpat) before 2.4.5, an attacker can trigger stack exhaustion in build_model via a large nesting depth in the DTD element.
Publication Mise à jourCVE-2022-23990
Expat (aka libexpat) before 2.4.4 has an integer overflow in the doProlog function.
Publication Mise à jourCVE-2022-23852
