{"id":"DEBIAN-CVE-2009-4488","details":"Varnish 2.0.6 writes data to a log file without sanitizing non-printable characters, which might allow remote attackers to modify a window's title, or possibly execute arbitrary commands or overwrite files, via an HTTP request containing an escape sequence for a terminal emulator.  NOTE: the vendor disputes the significance of this report, stating that \"This is not a security problem in Varnish or any other piece of software which writes a logfile. The real problem is the mistaken belief that you can cat(1) a random logfile to your terminal safely.","modified":"2026-09-22T17:00:21.243790423Z","published":"2010-01-13T20:30:00.390Z","upstream":["CVE-2009-4488"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2009-4488"}],"affected":[{"package":{"name":"varnish","ecosystem":"Debian:12","purl":"pkg:deb/debian/varnish?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["7.1.1-1.1","7.1.1-1.1+deb12u1","7.1.1-1.2","7.1.1-2+deb12u1","7.5.0-1","7.5.0-2","7.5.0-3","7.6.0-1","7.6.0-2","7.6.1-1","7.6.1-2","7.7.0-1","7.7.0-2","7.7.0-3","7.7.1-1","7.7.2-1","7.7.2-2","7.7.3-1","7.7.3-2","7.7.3-3"],"ecosystem_specific":{"urgency":"unimportant"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2009-4488.json"}},{"package":{"name":"varnish","ecosystem":"Debian:13","purl":"pkg:deb/debian/varnish?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["7.7.0-3","7.7.0-3+deb13u1","7.7.1-1","7.7.2-1","7.7.2-2","7.7.3-1","7.7.3-2","7.7.3-3"],"ecosystem_specific":{"urgency":"unimportant"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2009-4488.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
