CVE-2016-4472 not yet assigned priority: Debian including 2 source packages (expat, libxmltok), 7 status rows across 5 suites (bookworm, bullseye, forky, sid, trixie): resolved 5, open 2.
The overflow protection in Expat is removed by compilers with certain optimization settings, which allows remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via crafted XML data. NOTE: this vulnerability exists because of an incomplete fix for CVE-2015-1283 and CVE-2015-2716.
