{"id":"UBUNTU-CVE-2014-6278","details":"GNU Bash through 4.3 bash43-026 does not properly parse function definitions in the values of environment variables, which allows remote attackers to execute arbitrary commands 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, CVE-2014-7169, and CVE-2014-6277.","modified":"2026-02-04T03:31:36.790419Z","published":"2014-09-30T00:00:00Z","related":["USN-2380-1"],"upstream":["CVE-2014-6278"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2014-6278"},{"type":"REPORT","url":"http://lcamtuf.blogspot.ca/2014/09/bash-bug-apply-unofficial-patch-now.html"},{"type":"REPORT","url":"http://seclists.org/fulldisclosure/2014/Oct/9"},{"type":"REPORT","url":"http://lcamtuf.blogspot.ca/2014/10/bash-bug-how-we-finally-cracked.html"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-2380-1"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2014-6278"},{"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@4.3-7ubuntu1.5?arch=source&distro=trusty"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.3-7ubuntu1.5"}]}],"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","4.3-7ubuntu1.3","4.3-7ubuntu1.4"],"ecosystem_specific":{"availability":"No subscription required","binaries":[{"binary_name":"bash","binary_version":"4.3-7ubuntu1.5"},{"binary_name":"bash-builtins","binary_version":"4.3-7ubuntu1.5"},{"binary_name":"bash-static","binary_version":"4.3-7ubuntu1.5"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2014/UBUNTU-CVE-2014-6278.json"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H"},{"type":"Ubuntu","score":"medium"}]}
