CVE-2020-15694

In Nim 1.2.4, the standard library httpClient fails to properly validate the server response. For example, httpClient.get().contentLength() does not raise any error if a malicious server provides a negative Content-Length.

This update for nim fixes the following issues:

Includes upstream security fixes for:

• (boo#1175333, CVE-2020-15693) httpClient is vulnerable to a CR-LF injection
• (boo#1175334, CVE-2020-15692) mishandle of argument to browsers.openDefaultBrowser
• (boo#1175332, CVE-2020-15694) httpClient.get().contentLength() fails to properly validate the server response
• (boo#1192712, CVE-2021-41259) null byte accepted in getContent function, leading to URI validation bypass
• (boo#1185948, CVE-2021-29495) stdlib httpClient does not validate peer certificates by default
• (boo#1185085, CVE-2021-21374) Improper verification of the SSL/TLS certificate
• (boo#1185084, CVE-2021-21373) 'nimble refresh' falls back to a non-TLS URL in case of error
• (boo#1185083, CVE-2021-21372) doCmd can be leveraged to execute arbitrary commands
• (boo#1181705, CVE-2020-15690) Standard library asyncftpclient lacks a check for newline character

Following nim tools now work as expected:

• nim_dbg is now installed.
• nim-gdb can be successfully launched as it finds and loads nim-gdb.py correctly under gdb.
• nimble package manager stores package information per user.
• compiler package can be found and used, as it may be required by other packages.

Update to 1.6.6

• standard library use consistent styles for variable names so it can be used in projects which force a consistent style with --styleCheck:usages option.
• ARC/ORC are now considerably faster at method dispatching, bringing its performance back on the level of the refc memory management.
