- Summary
- libxml2: Fix of 2 CVEs
- Details
-
- CVE-2026-86143: guard the size_t buffer length against INT_MAX before it is narrowed to the int passed to writecallback in xmlOutputBufferWrite(), xmlOutputBufferWriteEscape() and xmlOutputBufferFlush() (xmlIO.c), so a negative length can no longer reach an output callback
- CVE-2026-86144: propagate the document's parseFlags in xmlXIncludeProcess() and xmlXIncludeProcessTree() and apply them to the parse="text" sub-context in xmlXIncludeLoadTxt() (xinclude.c), so XML_PARSE_NONET is honoured during XInclude resolution
