[slackware-security] expat (SSA:2022-025-01)

New expat packages are available for Slackware 14.0, 14.1, 14.2, and -current
to fix a security issue.


Here are the details from the Slackware 14.2 ChangeLog:
+--------------------------+
patches/packages/expat-2.4.3-i586-2_slack14.2.txz: Rebuilt.
Fix signed integer overflow in function XML_GetBuffer for when
XML_CONTEXT_BYTES is defined to >0 (which is both common and
default). Impact is denial of service or other undefined behavior.
While we're here, also patch a memory leak on output file opening error.
Thanks to marav.
