{"id":"UBUNTU-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":"2026-04-22T08:43:40.785675Z","published":"2010-01-13T20:30:00Z","upstream":["CVE-2009-4488"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2009-4488"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2009-4488"}],"affected":[{"package":{"name":"varnish","ecosystem":"Ubuntu:14.04:LTS","purl":"pkg:deb/ubuntu/varnish@3.0.5-2ubuntu0.1?arch=source&distro=trusty"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.0.4-1ubuntu1","3.0.4-1ubuntu2","3.0.5-1ubuntu2","3.0.5-2","3.0.5-2ubuntu0.1"],"ecosystem_specific":{"binaries":[{"binary_version":"3.0.5-2ubuntu0.1","binary_name":"libvarnishapi1"},{"binary_version":"3.0.5-2ubuntu0.1","binary_name":"varnish"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2009/UBUNTU-CVE-2009-4488.json"}},{"package":{"name":"varnish","ecosystem":"Ubuntu:Pro:16.04:LTS","purl":"pkg:deb/ubuntu/varnish@4.1.1-1ubuntu0.2+esm1?arch=source&distro=esm-apps/xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["4.0.3-1","4.1.0-1","4.1.0-2","4.1.1-1","4.1.1-1ubuntu0.2","4.1.1-1ubuntu0.2+esm1"],"ecosystem_specific":{"binaries":[{"binary_version":"4.1.1-1ubuntu0.2+esm1","binary_name":"libvarnishapi1"},{"binary_version":"4.1.1-1ubuntu0.2+esm1","binary_name":"varnish"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2009/UBUNTU-CVE-2009-4488.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:H/I:H/A:H"},{"type":"Ubuntu","score":"negligible"}]}
