{"id":"USN-3538-1","summary":"openssh vulnerabilities","details":"Jann Horn discovered that OpenSSH incorrectly loaded PKCS#11 modules from\nuntrusted directories. A remote attacker could possibly use this issue to\nexecute arbitrary PKCS#11 modules. This issue only affected Ubuntu 14.04\nLTS and Ubuntu 16.04 LTS. (CVE-2016-10009)\n\nJann Horn discovered that OpenSSH incorrectly handled permissions on\nUnix-domain sockets when privilege separation is disabled. A local attacker\ncould possibly use this issue to gain privileges. This issue only affected\nUbuntu 16.04 LTS. (CVE-2016-10010)\n\nJann Horn discovered that OpenSSH incorrectly handled certain buffer memory\noperations. A local attacker could possibly use this issue to obtain\nsensitive information. This issue only affected Ubuntu 14.04 LTS and Ubuntu\n16.04 LTS. (CVE-2016-10011)\n\nGuido Vranken discovered that OpenSSH incorrectly handled certain shared\nmemory manager operations. A local attacker could possibly use issue to\ngain privileges. This issue only affected Ubuntu 14.04 LTS and Ubuntu 16.04\nLTS. This issue only affected Ubuntu 14.04 LTS and Ubuntu 16.04 LTS.\n(CVE-2016-10012)\n\nMichal Zalewski discovered that OpenSSH incorrectly prevented write\noperations in readonly mode. A remote attacker could possibly use this\nissue to create zero-length files, leading to a denial of service.\n(CVE-2017-15906)\n","modified":"2026-02-10T04:41:16Z","published":"2018-01-22T16:50:31Z","related":["UBUNTU-CVE-2016-10009","UBUNTU-CVE-2016-10010","UBUNTU-CVE-2016-10011","UBUNTU-CVE-2016-10012","UBUNTU-CVE-2017-15906"],"upstream":["CVE-2016-10009","CVE-2016-10010","CVE-2016-10011","CVE-2016-10012","CVE-2017-15906","UBUNTU-CVE-2016-10009","UBUNTU-CVE-2016-10010","UBUNTU-CVE-2016-10011","UBUNTU-CVE-2016-10012","UBUNTU-CVE-2017-15906"],"references":[{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-3538-1"},{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2016-10009"},{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2016-10010"},{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2016-10011"},{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2016-10012"},{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2017-15906"}],"affected":[{"package":{"name":"openssh","ecosystem":"Ubuntu:14.04:LTS","purl":"pkg:deb/ubuntu/openssh@1:6.6p1-2ubuntu2.10?arch=source&distro=trusty"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1:6.6p1-2ubuntu2.10"}]}],"versions":["1:6.2p2-6","1:6.2p2-6ubuntu1","1:6.4p1-1","1:6.4p1-2","1:6.5p1-1","1:6.5p1-2","1:6.5p1-3","1:6.5p1-4","1:6.5p1-6","1:6.6p1-1","1:6.6p1-2","1:6.6p1-2ubuntu1","1:6.6p1-2ubuntu2","1:6.6p1-2ubuntu2.2","1:6.6p1-2ubuntu2.3","1:6.6p1-2ubuntu2.4","1:6.6p1-2ubuntu2.6","1:6.6p1-2ubuntu2.7","1:6.6p1-2ubuntu2.8"],"ecosystem_specific":{"availability":"No subscription required","binaries":[{"binary_version":"1:6.6p1-2ubuntu2.10","binary_name":"openssh-client"},{"binary_version":"1:6.6p1-2ubuntu2.10","binary_name":"openssh-server"},{"binary_version":"1:6.6p1-2ubuntu2.10","binary_name":"openssh-sftp-server"},{"binary_version":"1:6.6p1-2ubuntu2.10","binary_name":"ssh"},{"binary_version":"1:6.6p1-2ubuntu2.10","binary_name":"ssh-askpass-gnome"},{"binary_version":"1:6.6p1-2ubuntu2.10","binary_name":"ssh-krb5"}]},"database_specific":{"cves_map":{"cves":[{"severity":[{"score":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L","type":"CVSS_V3"},{"score":"low","type":"Ubuntu"}],"id":"CVE-2016-10009"},{"severity":[{"score":"CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","type":"CVSS_V3"},{"score":"low","type":"Ubuntu"}],"id":"CVE-2016-10011"},{"severity":[{"score":"CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","type":"CVSS_V3"},{"score":"low","type":"Ubuntu"}],"id":"CVE-2016-10012"},{"severity":[{"score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","type":"CVSS_V3"},{"score":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","type":"CVSS_V3"},{"score":"low","type":"Ubuntu"}],"id":"CVE-2017-15906"}],"ecosystem":"Ubuntu:14.04:LTS"},"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/usn/USN-3538-1.json"}},{"package":{"name":"openssh","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/openssh@1:7.2p2-4ubuntu2.4?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1:7.2p2-4ubuntu2.4"}]}],"versions":["1:6.9p1-2","1:6.9p1-3","1:7.1p1-1","1:7.1p1-3","1:7.1p1-4","1:7.1p1-6","1:7.1p2-1","1:7.1p2-2","1:7.2p1-1","1:7.2p2-1","1:7.2p2-2","1:7.2p2-3","1:7.2p2-4","1:7.2p2-4ubuntu1","1:7.2p2-4ubuntu2.1","1:7.2p2-4ubuntu2.2"],"ecosystem_specific":{"availability":"No subscription required","binaries":[{"binary_version":"1:7.2p2-4ubuntu2.4","binary_name":"openssh-client"},{"binary_version":"1:7.2p2-4ubuntu2.4","binary_name":"openssh-client-ssh1"},{"binary_version":"1:7.2p2-4ubuntu2.4","binary_name":"openssh-server"},{"binary_version":"1:7.2p2-4ubuntu2.4","binary_name":"openssh-sftp-server"},{"binary_version":"1:7.2p2-4ubuntu2.4","binary_name":"ssh"},{"binary_version":"1:7.2p2-4ubuntu2.4","binary_name":"ssh-askpass-gnome"},{"binary_version":"1:7.2p2-4ubuntu2.4","binary_name":"ssh-krb5"}]},"database_specific":{"cves_map":{"cves":[{"severity":[{"score":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L","type":"CVSS_V3"},{"score":"low","type":"Ubuntu"}],"id":"CVE-2016-10009"},{"severity":[{"score":"CVSS:3.0/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H","type":"CVSS_V3"},{"score":"low","type":"Ubuntu"}],"id":"CVE-2016-10010"},{"severity":[{"score":"CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","type":"CVSS_V3"},{"score":"low","type":"Ubuntu"}],"id":"CVE-2016-10011"},{"severity":[{"score":"CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","type":"CVSS_V3"},{"score":"low","type":"Ubuntu"}],"id":"CVE-2016-10012"},{"severity":[{"score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","type":"CVSS_V3"},{"score":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","type":"CVSS_V3"},{"score":"low","type":"Ubuntu"}],"id":"CVE-2017-15906"}],"ecosystem":"Ubuntu:16.04:LTS"},"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/usn/USN-3538-1.json"}}],"schema_version":"1.7.3"}
