security
Severity:
Critical
Release date:
2026-09-15 12:35:31 UTC
Description:
- CVE-2026-86143: reject output buffer lengths that do not fit in an int before calling writecallback in xmlOutputBufferWrite, xmlOutputBufferWriteEscape and xmlOutputBufferFlush, so that a negative length can no longer reach a write callback - CVE-2026-86144: propagate the document parse flags in xmlXIncludeProcess, xmlXIncludeProcessTree and xmlXIncludeLoadTxt so that options such as XML_PARSE_NONET are honoured during XInclude resolution
