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 ActualizaciónOpenJPEG allows OOB heap memory write in opj_jp2_read_header
OpenJPEG is an open-source JPEG 2000 codec. In OpenJPEG from 2.5.1 through 2.5.3, a call to opj_jp2_read_header may lead to OOB heap memory write when the data stream p_stream is too short and p_image is not initialized.
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.
