GHSA-9H9J-4VRJ-GF7G virtualenv writes prompt values into pyvenv.cfg without sanitizing line boundaries, allowing configuration injection

Summary pyvenv.cfg is a line-based format with no escape syntax. PyEnvCfg.write wrote values verbatim, while PyEnvCfg.readvalues parses the file with str.splitlines. A value containing a line boundary therefore became additional configuration lines, and because reading is last-wins, the injected...
