slackware
January 25, 2022
New expat packages are available for Slackware 14.0, 14.1, 14.2, and -current to fix a security issue
Summary
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. For more information, see: https://www.cve.org/CVERecord?id=CVE-2022-23852 (* Security fix *)
