{"id":"USN-3270-1","summary":"nss vulnerabilities","details":"Karthik Bhargavan and Gaetan Leurent discovered that the DES and Triple DES\nciphers were vulnerable to birthday attacks. A remote attacker could\npossibly use this flaw to obtain clear text data from long encrypted\nsessions. This update causes NSS to limit use of the same symmetric key.\n(CVE-2016-2183)\n\nIt was discovered that NSS incorrectly handled Base64 decoding. A remote\nattacker could use this flaw to cause NSS to crash, resulting in a denial\nof service, or possibly execute arbitrary code. (CVE-2017-5461)\n\nThis update refreshes the NSS package to version 3.28.4 which includes\nthe latest CA certificate bundle.\n","modified":"2026-02-10T04:41:07Z","published":"2017-04-27T16:47:55Z","related":["UBUNTU-CVE-2016-2183","UBUNTU-CVE-2017-5461"],"upstream":["CVE-2016-2183","CVE-2017-5461","UBUNTU-CVE-2016-2183","UBUNTU-CVE-2017-5461"],"references":[{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-3270-1"},{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2016-2183"},{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2017-5461"}],"affected":[{"package":{"name":"nss","ecosystem":"Ubuntu:14.04:LTS","purl":"pkg:deb/ubuntu/nss@2:3.28.4-0ubuntu0.14.04.1?arch=source&distro=trusty"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2:3.28.4-0ubuntu0.14.04.1"}]}],"versions":["2:3.15.1-1ubuntu1","2:3.15.2-1","2:3.15.3-1","2:3.15.3.1-1","2:3.15.3.1-1.1","2:3.15.3.1-1.1ubuntu1","2:3.15.4-1ubuntu3","2:3.15.4-1ubuntu4","2:3.15.4-1ubuntu5","2:3.15.4-1ubuntu6","2:3.15.4-1ubuntu7","2:3.15.4-1ubuntu7.1","2:3.17-0ubuntu0.14.04.1","2:3.17.1-0ubuntu0.14.04.1","2:3.17.1-0ubuntu0.14.04.2","2:3.17.4-0ubuntu0.14.04.1","2:3.19.2-0ubuntu0.14.04.1","2:3.19.2.1-0ubuntu0.14.04.1","2:3.19.2.1-0ubuntu0.14.04.2","2:3.21-0ubuntu0.14.04.1","2:3.21-0ubuntu0.14.04.2","2:3.23-0ubuntu0.14.04.1","2:3.26.2-0ubuntu0.14.04.3"],"ecosystem_specific":{"binaries":[{"binary_name":"libnss3","binary_version":"2:3.28.4-0ubuntu0.14.04.1"},{"binary_name":"libnss3-1d","binary_version":"2:3.28.4-0ubuntu0.14.04.1"},{"binary_name":"libnss3-dev","binary_version":"2:3.28.4-0ubuntu0.14.04.1"},{"binary_name":"libnss3-nssdb","binary_version":"2:3.28.4-0ubuntu0.14.04.1"},{"binary_name":"libnss3-tools","binary_version":"2:3.28.4-0ubuntu0.14.04.1"}],"availability":"No subscription required"},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/usn/USN-3270-1.json","cves_map":{"cves":[{"severity":[{"score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","type":"CVSS_V3"},{"score":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","type":"CVSS_V3"},{"score":"low","type":"Ubuntu"}],"id":"CVE-2016-2183"},{"severity":[{"score":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","type":"CVSS_V3"},{"score":"medium","type":"Ubuntu"}],"id":"CVE-2017-5461"}],"ecosystem":"Ubuntu:14.04:LTS"}}},{"package":{"name":"nss","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/nss@2:3.28.4-0ubuntu0.16.04.1?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2:3.28.4-0ubuntu0.16.04.1"}]}],"versions":["2:3.19.2-1ubuntu1","2:3.19.2.1-0ubuntu1","2:3.21-1ubuntu2","2:3.21-1ubuntu3","2:3.21-1ubuntu4","2:3.23-0ubuntu0.16.04.1","2:3.26.2-0ubuntu0.16.04.2"],"ecosystem_specific":{"binaries":[{"binary_name":"libnss3","binary_version":"2:3.28.4-0ubuntu0.16.04.1"},{"binary_name":"libnss3-1d","binary_version":"2:3.28.4-0ubuntu0.16.04.1"},{"binary_name":"libnss3-dev","binary_version":"2:3.28.4-0ubuntu0.16.04.1"},{"binary_name":"libnss3-nssdb","binary_version":"2:3.28.4-0ubuntu0.16.04.1"},{"binary_name":"libnss3-tools","binary_version":"2:3.28.4-0ubuntu0.16.04.1"}],"availability":"No subscription required"},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/usn/USN-3270-1.json","cves_map":{"cves":[{"severity":[{"score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","type":"CVSS_V3"},{"score":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","type":"CVSS_V3"},{"score":"low","type":"Ubuntu"}],"id":"CVE-2016-2183"},{"severity":[{"score":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","type":"CVSS_V3"},{"score":"medium","type":"Ubuntu"}],"id":"CVE-2017-5461"}],"ecosystem":"Ubuntu:16.04:LTS"}}}],"schema_version":"1.7.3"}
