CVE-2016-4472

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.

Tim Boddy, Gustavo Grieco and others discovered that Expat, that is integrated in xmltok library, incorrectly handled certain files. An attacker could possibly use these issues to cause a denial of service, or possibly execute arbitrary code. These issues were only addressed in Ubuntu 16.04 ESM.

It was discovered that Expat, that is integrated in xmltok library, incorrectly handled encoding validation of certain files. An attacker could possibly use this issue to cause a denial of service, or possibly execute arbitrary code. (CVE-2022-25235)

It was discovered that Expat, that is integrated in xmltok library, incorrectly handled namespace URIs of certain files. An attacker could possibly use this issue to cause a denial of service, or possibly execute arbitrary code. (CVE-2022-25236)

It was discovered that Expat, contained within the xmltok library, incorrectly handled malformed XML data. If a user or application were tricked into opening a crafted XML file, an attacker could cause a denial of service, or possibly execute arbitrary code. (CVE-2015-1283, CVE-2016-0718, CVE-2016-4472, CVE-2019-15903)

It was discovered that Expat, contained within the xmltok library, incorrectly handled XML data containing a large number of colons, which could lead to excessive resource consumption. If a user or application were tricked into opening a crafted XML file, an attacker could possibly use this issue to cause a denial of service. (CVE-2018-20843)

It was discovered that Expat, contained within the xmltok library, incorrectly handled certain input, which could lead to an integer overflow. If a user or application were tricked into opening a crafted XML file, an attacker could possibly use this issue to cause a denial of service.
