{"id":"DEBIAN-CVE-2006-0056","details":"Double free vulnerability in the authentication and authentication token alteration code in PAM-MySQL 0.6.x before 0.6.2 and 0.7.x before 0.7pre3 allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via crafted passwords, which lead to a double free of a pointer that was created by the pam_get_item function.  NOTE: this issue only occurs in certain configurations in which there are multiple PAM modules, PAM-MySQL is not evaluated first, and there are no requisite modules before PAM-MySQL.","modified":"2026-09-17T06:47:40.091835598Z","published":"2006-02-13T11:06:00Z","upstream":["CVE-2006-0056"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2006-0056"}],"affected":[{"package":{"name":"pam-mysql","ecosystem":"Debian:12","purl":"pkg:deb/debian/pam-mysql?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.6.2-1"}]}],"ecosystem_specific":{"urgency":"medium"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2006-0056.json"}},{"package":{"name":"pam-mysql","ecosystem":"Debian:13","purl":"pkg:deb/debian/pam-mysql?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.6.2-1"}]}],"ecosystem_specific":{"urgency":"medium"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2006-0056.json"}},{"package":{"name":"pam-mysql","ecosystem":"Debian:14","purl":"pkg:deb/debian/pam-mysql?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.6.2-1"}]}],"ecosystem_specific":{"urgency":"medium"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2006-0056.json"}}],"schema_version":"1.9.0"}
