The chan_sip channel driver has a liberal definition for whitespace when attempting to strip the content between a SIP header name and a colon character. Rather than following RFC 3261 and stripping only spaces and horizontal tabs, Asterisk treats any non-printable ASCII character as if it were whitespace. This means that headers such as Contact\\x01: will be seen as a valid Contact header. This mostly does not pose a problem until Asterisk is placed in tandem with an authenticating SIP proxy. In such a case, a crafty combination of valid and invalid To headers can cause a proxy to allow an INVITE request into Asterisk without authentication since it believes the request is an in-dialog request. However, because of the bug described above, the request will look like an out-of-dialog request to Asterisk. Asterisk will then process the request as a new call. The result is that Asterisk can process calls from unvetted sources without any authentication. If you do not use a proxy for authentication, then this issue does not affect you. If your proxy is dialog-aware (meaning that the proxy keeps track of what dialogs are currently valid), then this issue does not affect you. If you use chan_pjsip instead of chan_sip, then this issue does not affect you.","references":[{"reference_url":"https://api.first.org/data/v1/epss?cve=CVE-2016-9938","reference_id":"","reference_type":"","scores":[{"value":"0.01419","scoring_system":"epss","scoring_elements":"0.80524","published_at":"2026-04-01T12:55:00Z"},{"value":"0.01419","scoring_system":"epss","scoring_elements":"0.80531","published_at":"2026-04-02T12:55:00Z"},{"value":"0.01419","scoring_system":"epss","scoring_elements":"0.80553","published_at":"2026-04-04T12:55:00Z"},{"value":"0.01419","scoring_system":"epss","scoring_elements":"0.80545","published_at":"2026-04-07T12:55:00Z"},{"value":"0.01419","scoring_system":"epss","scoring_elements":"0.80574","published_at":"2026-04-08T12:55:00Z"},{"value":"0.01419","scoring_system":"epss","scoring_elements":"0.80584","published_at":"2026-04-09T12:55:00Z"},{"value":"0.01419","scoring_system":"epss","scoring_elements":"0.80601","published_at":"2026-04-11T12:55:00Z"},{"value":"0.01419","scoring_system":"epss","scoring_elements":"0.80587","published_at":"2026-04-12T12:55:00Z"},{"value":"0.01419","scoring_system":"epss","scoring_elements":"0.80579","published_at":"2026-04-13T12:55:00Z"},{"value":"0.01419","scoring_system":"epss","scoring_elements":"0.80608","published_at":"2026-04-16T12:55:00Z"},{"value":"0.01419","scoring_system":"epss","scoring_elements":"0.8061","published_at":"2026-04-18T12:55:00Z"},{"value":"0.01419","scoring_system":"epss","scoring_elements":"0.80614","published_at":"2026-04-21T12:55:00Z"},{"value":"0.01419","scoring_system":"epss","scoring_elements":"0.80638","published_at":"2026-04-24T12:55:00Z"},{"value":"0.01419","scoring_system":"epss","scoring_elements":"0.80641","published_at":"2026-04-26T12:55:00Z"},{"value":"0.01419","scoring_system":"epss","scoring_elements":"0.80657","published_at":"2026-04-29T12:55:00Z"},{"value":"0.01419","scoring_system":"epss","scoring_elements":"0.80676","published_at":"2026-05-05T12:55:00Z"},{"value":"0.01419","scoring_system":"epss","scoring_elements":"0.80697","published_at":"2026-05-07T12:55:00Z"},{"value":"0.01419","scoring_system":"epss","scoring_elements":"0.80716","published_at":"2026-05-09T12:55:00Z"},{"value":"0.01419","scoring_system":"epss","scoring_elements":"0.80711","published_at":"2026-05-11T12:55:00Z"},{"value":"0.01419","scoring_system":"epss","scoring_elements":"0.80728","published_at":"2026-05-12T12:55:00Z"},{"value":"0.01419","scoring_system":"epss","scoring_elements":"0.80771","published_at":"2026-05-14T12:55:00Z"}],"url":"https://api.first.org/data/v1/epss?cve=CVE-2016-9938"},{"reference_url":"https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2016-9938","reference_id":"","reference_type":"","scores":[],"url":"https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2016-9938"},{"reference_url":"https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=847668","reference_id":"847668","reference_type":"","scores":[],"url":"https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=847668"}],"fixed_packages":[{"url":"http://public2.vulnerablecode.io/api/packages/583268?format=json","purl":"pkg:deb/debian/asterisk@1:13.13.1~dfsg-1?distro=sid","is_vulnerable":false,"affected_by_vulnerabilities":[],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:deb/debian/asterisk@1:13.13.1~dfsg-1%3Fdistro=sid"},{"url":"http://public2.vulnerablecode.io/api/packages/582067?format=json","purl":"pkg:deb/debian/asterisk@1:16.28.0~dfsg-0%2Bdeb11u4?distro=sid","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-r54j-ydjm-4uca"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:deb/debian/asterisk@1:16.28.0~dfsg-0%252Bdeb11u4%3Fdistro=sid"},{"url":"http://public2.vulnerablecode.io/api/packages/582068?format=json","purl":"pkg:deb/debian/asterisk@1:22.8.2%2Bdfsg%2B~cs6.15.60671435-1?distro=sid","is_vulnerable":false,"affected_by_vulnerabilities":[],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:deb/debian/asterisk@1:22.8.2%252Bdfsg%252B~cs6.15.60671435-1%3Fdistro=sid"},{"url":"http://public2.vulnerablecode.io/api/packages/1062442?format=json","purl":"pkg:deb/debian/asterisk@1:22.9.0%2Bdfsg%2B~cs6.16.60671434-1?distro=sid","is_vulnerable":false,"affected_by_vulnerabilities":[],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:deb/debian/asterisk@1:22.9.0%252Bdfsg%252B~cs6.16.60671434-1%3Fdistro=sid"}],"aliases":["CVE-2016-9938"],"risk_score":null,"exploitability":"0.5","weighted_severity":"0.0","resource_url":"http://public2.vulnerablecode.io/vulnerabilities/VCID-zzpx-gwmv-sfbz"}],"risk_score":null,"resource_url":"http://public2.vulnerablecode.io/packages/pkg:deb/debian/asterisk@1:13.13.1~dfsg-1%3Fdistro=sid"}
