{"id":"UBUNTU-CVE-2022-32206","details":"curl \u003c 7.84.0 supports \"chained\" HTTP compression algorithms, meaning that a serverresponse can be compressed multiple times and potentially with different algorithms. The number of acceptable \"links\" in this \"decompression chain\" was unbounded, allowing a malicious server to insert a virtually unlimited number of compression steps.The use of such a decompression chain could result in a \"malloc bomb\", makingcurl end up spending enormous amounts of allocated heap memory, or trying toand returning out of memory errors.","modified":"2026-04-22T15:33:51.370958Z","published":"2022-06-27T00:00:00Z","related":["USN-5495-1"],"upstream":["CVE-2022-32206"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2022-32206"},{"type":"REPORT","url":"https://curl.se/docs/CVE-2022-32206.html"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-5495-1"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2022-32206"}],"affected":[{"package":{"name":"curl","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/curl@7.58.0-2ubuntu3.19?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.58.0-2ubuntu3.19"}]}],"versions":["7.55.1-1ubuntu2","7.55.1-1ubuntu2.1","7.57.0-1ubuntu1","7.58.0-2ubuntu1","7.58.0-2ubuntu2","7.58.0-2ubuntu3","7.58.0-2ubuntu3.1","7.58.0-2ubuntu3.2","7.58.0-2ubuntu3.3","7.58.0-2ubuntu3.5","7.58.0-2ubuntu3.6","7.58.0-2ubuntu3.7","7.58.0-2ubuntu3.8","7.58.0-2ubuntu3.9","7.58.0-2ubuntu3.10","7.58.0-2ubuntu3.12","7.58.0-2ubuntu3.13","7.58.0-2ubuntu3.14","7.58.0-2ubuntu3.15","7.58.0-2ubuntu3.16","7.58.0-2ubuntu3.17","7.58.0-2ubuntu3.18"],"ecosystem_specific":{"availability":"No subscription required","binaries":[{"binary_name":"curl","binary_version":"7.58.0-2ubuntu3.19"},{"binary_name":"libcurl3-gnutls","binary_version":"7.58.0-2ubuntu3.19"},{"binary_name":"libcurl3-nss","binary_version":"7.58.0-2ubuntu3.19"},{"binary_name":"libcurl4","binary_version":"7.58.0-2ubuntu3.19"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2022/UBUNTU-CVE-2022-32206.json"}},{"package":{"name":"curl","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/curl@7.68.0-1ubuntu2.12?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.68.0-1ubuntu2.12"}]}],"versions":["7.65.3-1ubuntu3","7.65.3-1ubuntu4","7.66.0-1ubuntu1","7.67.0-2ubuntu1","7.68.0-1ubuntu1","7.68.0-1ubuntu2","7.68.0-1ubuntu2.1","7.68.0-1ubuntu2.2","7.68.0-1ubuntu2.4","7.68.0-1ubuntu2.5","7.68.0-1ubuntu2.6","7.68.0-1ubuntu2.7","7.68.0-1ubuntu2.10","7.68.0-1ubuntu2.11"],"ecosystem_specific":{"availability":"No subscription required","binaries":[{"binary_name":"curl","binary_version":"7.68.0-1ubuntu2.12"},{"binary_name":"libcurl3-gnutls","binary_version":"7.68.0-1ubuntu2.12"},{"binary_name":"libcurl3-nss","binary_version":"7.68.0-1ubuntu2.12"},{"binary_name":"libcurl4","binary_version":"7.68.0-1ubuntu2.12"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2022/UBUNTU-CVE-2022-32206.json"}},{"package":{"name":"curl","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/curl@7.81.0-1ubuntu1.3?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.81.0-1ubuntu1.3"}]}],"versions":["7.74.0-1.3ubuntu2","7.74.0-1.3ubuntu3","7.80.0-3","7.81.0-1","7.81.0-1ubuntu1.1","7.81.0-1ubuntu1.2"],"ecosystem_specific":{"availability":"No subscription required","binaries":[{"binary_name":"curl","binary_version":"7.81.0-1ubuntu1.3"},{"binary_name":"libcurl3-gnutls","binary_version":"7.81.0-1ubuntu1.3"},{"binary_name":"libcurl3-nss","binary_version":"7.81.0-1ubuntu1.3"},{"binary_name":"libcurl4","binary_version":"7.81.0-1ubuntu1.3"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2022/UBUNTU-CVE-2022-32206.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H"},{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H"},{"type":"Ubuntu","score":"medium"}]}
