[Bug 1374715] Re: CVE links in the updater are invalid

[George Bateman]

Both links now work for me. I imagine that invalid links are allowed if and only if there is a CVE with the correct code, which would explain why this bug wasn't picked up in testing.
Nonetheless, I still think that we should add "CVE-" to  ensure that the correct error messages are shown even before the CVE is uploaded.

Title:
  CVE links in the updater are invalid

Status in “update-manager” package in Ubuntu:
  Triaged

Bug description:
  The auto-updater was asking for permission to update Bash. The "Changes" message was as follows:
  Changes for bash versions:
  Installed version: 4.3-7ubuntu1.3
  Available version: 4.3-7ubuntu1.4

  Version 4.3-7ubuntu1.4:

    * SECURITY UPDATE: out-of-bounds memory access
      - debian/patches/CVE-2014-718x.diff: guard against overflow and fix
        off-by-one in parse.y and y.tab.c.
      - CVE-2014-7186
      - CVE-2014-7187
    * SECURITY IMPROVEMENT: use prefixes and suffixes for function exports
      - debian/patches/variables-affix.diff: add prefixes and suffixes in
        variables.c.

  Each CVE link went to an URL such as http://cve.mitre.org/cgi-bin/cvename.cgi?name=2014-7186. This is an error page which states that the CVE_ID is invalid. I would have expected to see a bug description of some sort.
  Manually changing the URL to http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-7186 changed the error message, which now claims the ID is valid but unrecognised. I assume this is for the reason suggested, that the problem has not been uploaded, and that this is now the correct URL.
  Does the code that generates the links need to include "CVE-" in the URLs?

  I assume that this will apply to all updates, not just Bash, but I
  can't yet verify this.
