[slackware-security]  expat (SSA:2026-077-01)

New expat packages are available for Slackware 15.0 and -current to
fix security issues.


Here are the details from the Slackware 15.0 ChangeLog:
+--------------------------+
patches/packages/expat-2.7.5-i586-1_slack15.0.txz:  Upgraded.
  This update fixes security issues:
  Fix NULL function pointer dereference for empty external parameter entities;
  it takes use of both functions XML_ExternalEntityParserCreate and
  XML_SetParamEntityParsing for an application to be vulnerable.
  Protect from XML_TOK_INSTANCE_START infinite loop in function
  entityValueProcessor; it takes use of both functions
  XML_ExternalEntityParserCreate and XML_SetParamEntityParsing for an
  application to be vulnerable.
  Fix NULL dereference in function setContext on retry after an earlier
  ouf-of-memory condition; it takes use of function XML_ParserCreateNS or
  XML_ParserCreate_MM for an application to be vulnerable.
  For more information, see:
