{"id":"UBUNTU-CVE-2020-22916","details":"** DISPUTED ** An issue discovered in XZ 5.2.5 allows attackers to cause a denial of service via decompression of a crafted file. NOTE: the vendor disputes the claims of \"endless output\" and \"denial of service\" because decompression of the 17,486 bytes always results in 114,881,179 bytes, which is often a reasonable size increase.","modified":"2023-08-22T19:16:00Z","published":"2023-08-22T19:16:00Z","withdrawn":"2025-06-23T15:53:43Z","references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2020-22916"},{"type":"REPORT","url":"https://tukaani.org/xz/"},{"type":"REPORT","url":"https://github.com/snappyJack/CVE-request-XZ-5.2.5-has-denial-of-service-vulnerability"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2020-22916"}],"affected":[{"package":{"name":"xz-utils","ecosystem":"Ubuntu:Pro:14.04:LTS","purl":"pkg:deb/ubuntu/xz-utils"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["5.1.1alpha+20120614-2ubuntu1","5.1.1alpha+20120614-2ubuntu2","5.1.1alpha+20120614-2ubuntu2.14.04.1+esm1"],"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2020/UBUNTU-CVE-2020-22916.json"}},{"package":{"name":"xz-utils","ecosystem":"Ubuntu:Pro:16.04:LTS","purl":"pkg:deb/ubuntu/xz-utils"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["5.1.1alpha+20120614-2ubuntu2","5.1.1alpha+20120614-2ubuntu2.16.04.1+esm1"],"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2020/UBUNTU-CVE-2020-22916.json"}},{"package":{"name":"xz-utils","ecosystem":"Ubuntu:Pro:18.04:LTS","purl":"pkg:deb/ubuntu/xz-utils"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["5.2.2-1.3","5.2.2-1.3ubuntu0.1"],"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2020/UBUNTU-CVE-2020-22916.json"}},{"package":{"name":"xz-utils","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/xz-utils"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["5.2.4-1","5.2.4-1ubuntu1","5.2.4-1ubuntu1.1"],"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2020/UBUNTU-CVE-2020-22916.json"}},{"package":{"name":"xz-utils","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/xz-utils"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["5.2.5-2","5.2.5-2build1","5.2.5-2build2","5.2.5-2ubuntu1"],"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2020/UBUNTU-CVE-2020-22916.json"}},{"package":{"name":"xz-utils","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/xz-utils"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["5.4.1-0.2","5.4.4-0.1","5.4.5-0.1","5.4.5-0.3","5.6.0-0.2","5.6.1+really5.4.5-1"],"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2020/UBUNTU-CVE-2020-22916.json"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H"}]}
