{"id":"UBUNTU-CVE-2018-14622","details":"A null-pointer dereference vulnerability was found in libtirpc before version 0.3.3-rc3. The return value of makefd_xprt() was not checked in all instances, which could lead to a crash when the server exhausted the maximum number of available file descriptors. A remote attacker could cause an rpc-based application to crash by flooding it with new connections.","modified":"2026-04-22T11:46:06.472052Z","published":"2018-08-30T00:00:00Z","related":["USN-3759-1","USN-3759-2"],"upstream":["CVE-2018-14622"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2018-14622"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=1620293"},{"type":"REPORT","url":"https://bugzilla.novell.com/show_bug.cgi?id=968175"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-14622"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-3759-1"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-3759-2"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2018-14622"}],"affected":[{"package":{"name":"libtirpc","ecosystem":"Ubuntu:14.04:LTS","purl":"pkg:deb/ubuntu/libtirpc@0.2.2-5ubuntu2.1?arch=source&distro=trusty"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.2.2-5ubuntu2.1"}]}],"versions":["0.2.2-5ubuntu1","0.2.2-5ubuntu2"],"ecosystem_specific":{"binaries":[{"binary_version":"0.2.2-5ubuntu2.1","binary_name":"libtirpc1"}],"availability":"No subscription required"},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2018/UBUNTU-CVE-2018-14622.json"}},{"package":{"name":"libtirpc","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/libtirpc@0.2.5-1ubuntu0.1?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.2.5-1ubuntu0.1"}]}],"versions":["0.2.5-1"],"ecosystem_specific":{"binaries":[{"binary_version":"0.2.5-1ubuntu0.1","binary_name":"libtirpc1"}],"availability":"No subscription required"},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2018/UBUNTU-CVE-2018-14622.json"}},{"package":{"name":"libtirpc","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/libtirpc@0.2.5-1.2ubuntu0.1?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.2.5-1.2ubuntu0.1"}]}],"versions":["0.2.5-1.2"],"ecosystem_specific":{"binaries":[{"binary_version":"0.2.5-1.2ubuntu0.1","binary_name":"libtirpc1"}],"availability":"No subscription required"},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2018/UBUNTU-CVE-2018-14622.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L"},{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},{"type":"Ubuntu","score":"medium"}]}
