GHSA-873q-wpqr-xfgw Bottle does not properly limit content-types

• PyPI bottle: >= 0.10.0, < 0.10.12 → fixed in 0.10.12 • PyPI bottle: >= 0.11.0, < 0.11.7 → fixed in 0.11.7 • PyPI bottle: >= 0.12.0, < 0.12.6 → fixed in 0.12.6

Bottle 0.10.x before 0.10.12, 0.11.x before 0.11.7, and 0.12.x before 0.12.6 does not properly limit content types, which allows remote attackers to bypass intended access restrictions via an accepted Content-Type followed by a `;` (semi-colon) and a Content-Type that would not be accepted, as demonstrated in YouCompleteMe to execute arbitrary code.
