{"id":"USN-6429-1","summary":"curl vulnerabilities","details":"Jay Satiro discovered that curl incorrectly handled hostnames when using a\nSOCKS5 proxy. In environments where curl is configured to use a SOCKS5\nproxy, a remote attacker could possibly use this issue to execute arbitrary\ncode. This issue only affected Ubuntu 22.04 LTS, and Ubuntu 23.04.\n(CVE-2023-38545)\n\nIt was discovered that curl incorrectly handled cookies when an application\nduplicated certain handles. A local attacker could possibly create a cookie\nfile and inject arbitrary cookies into subsequent connections.\n(CVE-2023-38546)\n","modified":"2026-02-10T04:43:22Z","published":"2023-10-11T11:34:51Z","related":["UBUNTU-CVE-2023-38545","UBUNTU-CVE-2023-38546"],"upstream":["CVE-2023-38545","CVE-2023-38546","UBUNTU-CVE-2023-38545","UBUNTU-CVE-2023-38546"],"references":[{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-6429-1"},{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2023-38545"},{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2023-38546"}],"affected":[{"package":{"name":"curl","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/curl@7.68.0-1ubuntu2.20?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.68.0-1ubuntu2.20"}]}],"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","7.68.0-1ubuntu2.12","7.68.0-1ubuntu2.13","7.68.0-1ubuntu2.14","7.68.0-1ubuntu2.15","7.68.0-1ubuntu2.16","7.68.0-1ubuntu2.18","7.68.0-1ubuntu2.19"],"ecosystem_specific":{"binaries":[{"binary_name":"curl","binary_version":"7.68.0-1ubuntu2.20"},{"binary_name":"libcurl3-gnutls","binary_version":"7.68.0-1ubuntu2.20"},{"binary_name":"libcurl3-nss","binary_version":"7.68.0-1ubuntu2.20"},{"binary_name":"libcurl4","binary_version":"7.68.0-1ubuntu2.20"},{"binary_name":"libcurl4-gnutls-dev","binary_version":"7.68.0-1ubuntu2.20"},{"binary_name":"libcurl4-nss-dev","binary_version":"7.68.0-1ubuntu2.20"},{"binary_name":"libcurl4-openssl-dev","binary_version":"7.68.0-1ubuntu2.20"}],"availability":"No subscription required"},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/usn/USN-6429-1.json","cves_map":{"ecosystem":"Ubuntu:20.04:LTS","cves":[{"id":"CVE-2023-38546","severity":[{"score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:N","type":"CVSS_V3"},{"score":"low","type":"Ubuntu"}]}]}}},{"package":{"name":"curl","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/curl@7.81.0-1ubuntu1.14?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.81.0-1ubuntu1.14"}]}],"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","7.81.0-1ubuntu1.3","7.81.0-1ubuntu1.4","7.81.0-1ubuntu1.6","7.81.0-1ubuntu1.7","7.81.0-1ubuntu1.8","7.81.0-1ubuntu1.10","7.81.0-1ubuntu1.11","7.81.0-1ubuntu1.13"],"ecosystem_specific":{"binaries":[{"binary_name":"curl","binary_version":"7.81.0-1ubuntu1.14"},{"binary_name":"libcurl3-gnutls","binary_version":"7.81.0-1ubuntu1.14"},{"binary_name":"libcurl3-nss","binary_version":"7.81.0-1ubuntu1.14"},{"binary_name":"libcurl4","binary_version":"7.81.0-1ubuntu1.14"},{"binary_name":"libcurl4-gnutls-dev","binary_version":"7.81.0-1ubuntu1.14"},{"binary_name":"libcurl4-nss-dev","binary_version":"7.81.0-1ubuntu1.14"},{"binary_name":"libcurl4-openssl-dev","binary_version":"7.81.0-1ubuntu1.14"}],"availability":"No subscription required"},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/usn/USN-6429-1.json","cves_map":{"ecosystem":"Ubuntu:22.04:LTS","cves":[{"id":"CVE-2023-38545","severity":[{"score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","type":"CVSS_V3"},{"score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","type":"CVSS_V3"},{"score":"high","type":"Ubuntu"}]},{"id":"CVE-2023-38546","severity":[{"score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:N","type":"CVSS_V3"},{"score":"low","type":"Ubuntu"}]}]}}}],"schema_version":"1.7.3"}
