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.
libexpat before 2.8.2 has an integer overflow in XML_ParseBuffer because it lacked a check that was present in XML_Parse.
An issue was discovered in libexpat before 2.6.3. xmlparse.c does not reject a negative length for XML_ParseBuffer.
libexpat before 2.8.2 has an integer overflow in copyString.
libexpat before 2.8.2 has an integer overflow in getAttributeId.
libexpat before 2.8.2 has an integer overflow in storeAtts.
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.
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 2.7.5 allows an infinite loop while parsing DTD content.
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).
libexpat before 2.8.2 has an integer overflow in doProlog that is related to storeEntityValue and entity textLen.
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).
libexpat before 2.7.5 allows a NULL pointer dereference with empty external parameter entity content.
libexif through 0.6.25 has a flaw in decoding MakerNotes. If the exif_mnote_data_get_value function gets passed in a 0 size, the passed in-buffer would be overwritten due to an integer underflow.
Lexbor is a web browser engine library. Prior to 2.7.0, the ISO‑2022‑JP encoder in Lexbor fails to reset the temporary size variable between iterations. The statement ctx->buffer_used -= size with a s
libexpat before 2.8.2 has an integer overflow in addBinding.
In libexpat before 2.7.4, XML_ExternalEntityParserCreate does not copy unknown encoding handler user data.
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 2.8.2 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 u
In the Linux kernel, the following vulnerability has been resolved:
