[slackware-security]  expat (SSA:2026-223-01)

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


Here are the details from the Slackware 15.0 ChangeLog:
+--------------------------+
patches/packages/expat-2.7.5-i586-3_slack15.0.txz:  Rebuilt.
  This update fixes a security issue:
  Fix an out-of-bounds read and the resulting infinite loop caused by treating
  low surrogates (Unicode) the same as high surrogates in functions *_toUtf16.
  For more information, see:
    https://www.cve.org/CVERecord?id=CVE-2026-72522
  (* Security fix *)
