+Privoxy 3.0.33 fixes an XSS issue and multiple DoS issues and a couple of other + bugs. The issues also affect earlier Privoxy releases. Privoxy 3.0.33 also comes + with a couple of general improvements an new features.
+Changes in Privoxy 3.0.33 stable:
- -
Security/Reliability:
+Bug fixes:
- -
+ssplit(): Remove an assertion that could be triggered with a crafted CGI request. Commit 2256d7b4d67. - OVE-20210203-0001. Reported by: Joshua Rogers (Opera)
+handle_established_connection(): Skip the poll()/select() calls if TLS data is pending on the server + socket. The TLS library may have already consumed all the data from the server response in which case + poll() and select() will not detect that data is available to be read. Fixes SF bug #926 reported by Wen + Yue.
+- +
continue_https_chat(): Update csp->server_connection.request_sent after sending the request to make + sure the latency is calculated correctly. Previously https connections were not reused after timeout + seconds after the first request made on the connection.
- -
cgi_send_banner(): Overrule invalid image types. Prevents a crash with a crafted CGI request if Privoxy - is toggled off. Commit e711c505c48. OVE-20210206-0001. Reported by: Joshua Rogers (Opera)
+free_pattern_spec(): Don't try to free an invalid pointer when unloading an action file with a TAG + pattern while Privoxy has been compiled without FEATURE_PCRE_HOST_PATTERNS. Closes: SF patch request #147. + Patch by Maxim Antonov.
- -
socks5_connect(): Don't try to send credentials when none are configured. Fixes a crash due to a - NULL-pointer dereference when the socks server misbehaves. Commit 85817cc55b9. OVE-20210207-0001. Reported - by: Joshua Rogers (Opera)
+Establish the TLS connection with the client earlier and decide how to route the request afterwards. + This allows to change the forwarding settings based on information from the https-inspected request, for + example the path.
- -
chunked_body_is_complete(): Prevent an invalid read of size two. Commit a912ba7bc9c. OVE-20210205-0001. - Reported by: Joshua Rogers (Opera)
+Adjust build_request_line() to create a CONNECT request line when https-inspecting and forwarding to a + HTTP proxy. Fixes SF bug #925 reported by Wen Yue.
- -
Obsolete pcre: Prevent invalid memory accesses with an invalid pattern passed to pcre_compile(). Note - that the obsolete pcre code is scheduled to be removed before the 3.0.33 release. There has been a warning - since 2008 already. Commit 28512e5b624. OVE-20210222-0001. Reported by: Joshua Rogers (Opera)
+load_config(): Add a space that was missing in a log message.
- -
Bug fixes:
+General improvements:
- -
+Properly parse the client-tag-lifetime directive. Previously it was not accepted as an obsolete hash - value was being used. Reported by: Joshua Rogers (Opera)
+serve(): Close the client socket as well if the server socket for an inspected connection has been + closed. Privoxy currently can't establish a new server connection when the client socket is reused and + would drop the connection in continue_https_chat() anyway.
+- +
+Don't disable redirect checkers in redirect_url() Disable them in handle_established_connection() + instead. Doing it in redirect_url() prevented the +redirect{} and +fast-redirects{} actions from being + logged with LOG_LEVEL_ACTIONS.
+- +
+handle_established_connection(): Slightly improve a comment
+- +
+handle_established_connection(): Fix a comment
+- +
socks5_connect(): Fix indentation.
- -
decompress_iob(): Prevent reading of uninitialized data. Reported by: Joshua Rogers (Opera).
+handle_established_connection(): Improve an error message
- -
decompress_iob(): Don't advance cur past eod when looking for the end of the file name and comment.
+create_pattern_spec(): Fix ifdef indentation
- -
decompress_iob(): Cast value to unsigned char before shifting. Prevents a left-shift of a negative value - which is undefined behaviour. Reported by: Joshua Rogers (Opera)
+Fix comment typos
- -
gif_deanimate(): Confirm that that we have enough data before doing any work. Fixes a crash when fuzzing - with an empty document. Reported by: Joshua Rogers (Opera).
+Add a CGI handler for /wpad.dat that returns a Proxy Auto-Configuration (PAC) file. Among other things, + it can be used to instruct clients through DHCP to use Privoxy as proxy. For example with the dnsmasq + option: dhcp-option=252,http://config.privoxy.org/wpad.dat Initial patch by Richard Schneidt.
- -
buf_copy(): Fail if there's no data to write or nothing to do. Prevents undefined behaviour "applying - zero offset to null pointer". Reported by: Joshua Rogers (Opera)
+listen_loop(): When shutting down gracefully, close listening ports before waiting for the threads to + exit. Allows to start a second Privoxy with the same config file while the first Privoxy is still + running.
- -
log_error(): Treat LOG_LEVEL_FATAL as fatal even when --stfu is being used while fuzzing. Reported by: - Joshua Rogers (Opera).
+Allow to edit the add-header action through the CGI editor by generalizing the code that got added with + the suppress-tag action. Closes SF patch request #146. Patch by Maxim Antonov.
- -
Respect DESTDIR when considering whether or not to install config files with ".new" extension.
+process_encrypted_request(): Improve a log message The function only processes request headers and there + may still be unread request body data left to process.
- -
OpenSSL ssl_store_cert(): Fix two error messages.
+read_http_request_body(): Fix two error messages that used an incorrect variable.
- -
Fix a couple of format specifiers.
+chat(): Log the applied actions before deciding how to forward the request.
- -
Silence compiler warnings when compiling with NDEBUG.
+parse_time_header(): Silence a coverity complaint when building without assertions.
- -
fuzz_server_header(): Fix compiler warning.
+receive_encrypted_request_headers(): Improve a log message
- -
fuzz_client_header(): Fix compiler warning.
+mbedTLS get_ciphersuites_from_string(): Use strlcpy() instead of strncpy(). Previously the terminating + NUL wasn't copied which resulted in a compiler warning. This didn't cause actual problems as the target + buffer was initialized by zalloc_or_die() so the last byte of the target buffer was NUL already. Actually + copying the terminating NUL seems clearer, though.
- -
+cgi_send_user_manual(): Also reject requests if the user-manual directive specifies a https:// URL. - Previously Privoxy would try and fail to open a local file.
+Remove compiler warnings. "log_error(LOG_LEVEL_FATAL, ..." doesn't return but apparently the compiler + doesn't know that. Get rid of several "this statement may fall through [-Wimplicit-fallthrough=]" + warnings.
+- +
+If the the response is chunk-encoded, ignore the Content-Length header sent by the server. Allows to + load https://redmine.lighttpd.net/ with filtering enabled.
+- +
+Store the PEM certificate in a dynamically allocated buffer when https-inspecting. Should prevent errors + like: 2021-03-16 22:36:19.148 7f47bbfff700 Error: X509 PEM cert len 16694 is larger than buffer len 16383 + As a bonus it should slightly reduce the memory usage as most certificates are smaller than the previously + used fixed buffer. Reported by: Wen Yue
+- +
+Don't log the applied actions in process_encrypted_request() Log them in continue_https_chat() instead + to mirror chat(). Prevents the applied actions from getting logged twice for the first request on an + https-inspected connection.
+- +
+OpenSSL generate_host_certificate(): Use config.privoxy.org as Common Name Org and Org Unit if the real + host name is too long to get accepted by OpenSSL. Clients should only care about the Subject Alternative + Name anyway and we can continue to use the real host name for it. Reported by Miles Wen on + privoxy-users@.
+- +
+OpenSSL generate_host_certificate(): Fix two error messsages.
+- +
+Improve description of handle_established_connection()
+- +
+OpenSSL ssl_store_cert(): Translate EVP_PKEY_EC to a string.
+- +
+OpenSSL ssl_store_cert(): Remove pointless variable initialization.
+- +
OpenSSL ssl_store_cert(): Initialize pointer with NULL instead of 0.

+Add a "inactivity detection" mode Which can be useful for debugging purposes.
- -
continue_https_chat(): Explicitly unset CSP_FLAG_CLIENT_CONNECTION_KEEP_ALIVE if - process_encrypted_request() fails. This makes it more obvious that the connection will not be reused. - Previously serve() relied on CSP_FLAG_SERVER_CONTENT_LENGTH_SET and CSP_FLAG_CHUNKED being unset.
