Red Hat Security Advisory: mingw-expat security update

Notes

Topic
An update for mingw-expat is now available for Red Hat Enterprise Linux 8. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
Details
Expat is a C library for parsing XML documents. The mingw-expat packages provide a port of the Expat library for MinGW. The following packages have been upgraded to a later upstream version: mingw-expat (2.4.8). (BZ#2057023, BZ#2057037, BZ#2057127) Security Fix(es): * expat: Malformed 2- and 3-byte UTF-8 sequences can lead to arbitrary code execution (CVE-2022-25235) * expat: Namespace-separator characters in "xmlns[:prefix]" attribute values can lead to arbitrary code execution (CVE-2022-25236) * expat: Integer overflow in storeRawNames() (CVE-2022-25315) * expat: Stack exhaustion in doctype parsing (CVE-2022-25313) * expat: Integer overflow in copyString() (CVE-2022-25314) * expat: Integer overflow in the doProlog function (CVE-2022-23990) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section. Additional Changes: For detailed information on changes in this release, see the Red Hat Enterprise Linux 8.7 Release Notes linked from the References section.
