libexpat before 2.8.4 lacks handler call depth tracking with custom encoding callbacks. Thus, a use-after-free can occur. NOTE: this is similar to CVE-2026-50219, CVE-2026-56131 and CVE-2026-56412. |
In libexpat 2.8.2 and 2.8.3 before 2.8.4, misinterpretation of getentropy's return code leads to insufficient entropy, which results in being vulnerable to hash flooding attacks, causing a denial of service via crafted X...Show more |
Expat through 2.8.3 contains a denial of service vulnerability caused by quadratic algorithmic complexity in the storeAtts() function in xmlparse.c, where processing N specified attributes with non-normalized values trig...Show more |
libexpat before 2.8.2 does not consider XML_TOK_DATA_CHARS in doCdataSection and thus lacks handler call depth tracking for various calls from within handlers in cases of a policy violation. Thus, a use-after-free can oc...Show more |
xmlwf in libexpat before 2.8.2 has an integer overflow in endDoctypeDecl via NOTATION declarations. |
xmlwf in libexpat before 2.8.2 has an integer overflow in resolveSystemId. |
xmlwf in libexpat before 2.8.2 has an integer overflow for the output filename when -d outputDir is used. |
libexpat before 2.8.2 has an integer overflow in copyString. |
libexpat before 2.8.2 has an integer overflow in doProlog that is related to storeEntityValue and entity textLen. |
libexpat before 2.8.2 has an integer overflow in XML_ParseBuffer because it lacked a check that was present in XML_Parse. |
libexpat before 2.8.2 has an integer overflow in getAttributeId. |
libexpat before 2.8.2 has an integer overflow in addBinding. |
libexpat before 2.8.2 has an integer overflow in storeAtts. |
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. |
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). |
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-fr...Show more |
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. |
libexpat before 2.8.0 uses insufficient entropy, and thus hash flooding can occur via a crafted XML document. |
libexpat before 2.7.5 allows a NULL pointer dereference in the function setContext on retry after an earlier ouf-of-memory condition. |
libexpat before 2.7.5 allows an infinite loop while parsing DTD content. |
