A CVE List V5 record names what it is about: a title such as "PAN-OS: Arbitrary File Creation Leads to OS Command Injection Vulnerability in GlobalProtect", a vendor and its products. None of it was kept, so a query for pan-os or prisma access only found records whose prose happened to say so. Every record now opens with the title in bold and a Vendor badge per affected vendor, refreshed from a local CVE List checkout in one pass and kept current by the daily sync for the records it fetches. Only the lines above the description move; descriptions and PoC sections are untouched. The pass also settled the heading link on cve.org and trimmed the stray space some version badges carried. The site index carries title, vendor and product for the 40 percent of indexed CVEs whose records have them. Search scores a hit in those above any position in the description, results show the title as a headline, and each page puts it under the CVE id, in the browser title, the meta description and an Affected row, with the block hubs listing it in place of the description's opening. The 35 MB metadata file the homepage needed before anything could be filtered is split in two for the page: the CVSS rows load with the rest, the advisories follow the index instead of competing with it for the connection. cve_metadata.json stays whole for anyone reading the API.

CVE-2016-9938
Description
An issue was discovered in Asterisk Open Source 11.x before 11.25.1, 13.x before 13.13.1, and 14.x before 14.2.1 and Certified Asterisk 11.x before 11.6-cert16 and 13.x before 13.8-cert4. 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.
