{"id":"UBUNTU-CVE-2014-7169","details":"GNU Bash through 4.3 bash43-025 processes trailing strings after certain malformed function definitions in the values of environment variables, which allows remote attackers to write to files or possibly have unknown other impact via a crafted environment, as demonstrated by vectors involving the ForceCommand feature in OpenSSH sshd, the mod_cgi and mod_cgid modules in the Apache HTTP Server, scripts executed by unspecified DHCP clients, and other situations in which setting the environment occurs across a privilege boundary from Bash execution.  NOTE: this vulnerability exists because of an incomplete fix for CVE-2014-6271.","modified":"2026-01-30T02:03:36.228752Z","published":"2014-09-25T00:00:00Z","related":["USN-2363-1","USN-2363-2"],"upstream":["CVE-2014-7169"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2014-7169"},{"type":"REPORT","url":"https://twitter.com/taviso/status/514887394294652929"},{"type":"REPORT","url":"http://www.openwall.com/lists/oss-security/2014/09/25/5"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-2363-1"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-2363-2"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2014-7169"},{"type":"REPORT","url":"https://www.cisa.gov/known-exploited-vulnerabilities-catalog"}],"affected":[{"package":{"name":"bash","ecosystem":"Ubuntu:14.04:LTS","purl":"pkg:deb/ubuntu/bash@4.3-7ubuntu1.3?arch=source&distro=trusty"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.3-7ubuntu1.3"}]}],"versions":["4.2-5ubuntu3","4.3-1ubuntu2","4.3-2ubuntu1","4.3-3ubuntu1","4.3-4ubuntu1","4.3-4ubuntu2","4.3-6ubuntu1","4.3-7ubuntu1","4.3-7ubuntu1.1","4.3-7ubuntu1.2"],"ecosystem_specific":{"binaries":[{"binary_name":"bash","binary_version":"4.3-7ubuntu1.3"},{"binary_name":"bash-builtins","binary_version":"4.3-7ubuntu1.3"},{"binary_name":"bash-static","binary_version":"4.3-7ubuntu1.3"}],"availability":"No subscription required"},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2014/UBUNTU-CVE-2014-7169.json"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","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:N/S:U/C:H/I:H/A:H"},{"type":"Ubuntu","score":"high"}]}
