1 September 2021, Privoxy 3.0.32 (stable) macOS installer V1.0 released.
5 This installer has been tested on Macs with Intel 64 bit processors running OS X 10.11 and higher. It may work on earlier releases, but is untested.
9 Privoxy 3.0.32 fixes multiple DoS issues and a couple of other bugs. The issues also affect earlier Privoxy releases. As such is recommended for all users.
13 - Security/Reliability:
14 - ssplit(): Remove an assertion that could be triggered with a
16 Commit 2256d7b4d67. OVE-20210203-0001.
17 Reported by: Joshua Rogers (Opera)
18 - cgi_send_banner(): Overrule invalid image types. Prevents a
19 crash with a crafted CGI request if Privoxy is toggled off.
20 Commit e711c505c48. OVE-20210206-0001.
21 Reported by: Joshua Rogers (Opera)
22 - socks5_connect(): Don't try to send credentials when none are
23 configured. Fixes a crash due to a NULL-pointer dereference
24 when the socks server misbehaves.
25 Commit 85817cc55b9. OVE-20210207-0001.
26 Reported by: Joshua Rogers (Opera)
27 - chunked_body_is_complete(): Prevent an invalid read of size two.
28 Commit a912ba7bc9c. OVE-20210205-0001.
29 Reported by: Joshua Rogers (Opera)
30 - Obsolete pcre: Prevent invalid memory accesses with an invalid
31 pattern passed to pcre_compile(). Note that the obsolete pcre code
32 is scheduled to be removed before the 3.0.33 release. There has been
33 a warning since 2008 already.
34 Commit 28512e5b624. OVE-20210222-0001.
35 Reported by: Joshua Rogers (Opera)
38 - Properly parse the client-tag-lifetime directive. Previously it was
39 not accepted as an obsolete hash value was being used.
40 Reported by: Joshua Rogers (Opera)
41 - decompress_iob(): Prevent reading of uninitialized data.
42 Reported by: Joshua Rogers (Opera).
43 - decompress_iob(): Don't advance cur past eod when looking
44 for the end of the file name and comment.
45 - decompress_iob(): Cast value to unsigned char before shifting.
46 Prevents a left-shift of a negative value which is undefined behaviour.
47 Reported by: Joshua Rogers (Opera)
48 - gif_deanimate(): Confirm that that we have enough data before doing
49 any work. Fixes a crash when fuzzing with an empty document.
50 Reported by: Joshua Rogers (Opera).
51 - buf_copy(): Fail if there's no data to write or nothing to do.
52 Prevents undefined behaviour "applying zero offset to null pointer".
53 Reported by: Joshua Rogers (Opera)
54 - log_error(): Treat LOG_LEVEL_FATAL as fatal even when --stfu is
55 being used while fuzzing.
56 Reported by: Joshua Rogers (Opera).
57 - Respect DESTDIR when considering whether or not to install
58 config files with ".new" extension.
59 - OpenSSL ssl_store_cert(): Fix two error messages.
60 - Fix a couple of format specifiers.
61 - Silence compiler warnings when compiling with NDEBUG.
62 - fuzz_server_header(): Fix compiler warning.
63 - fuzz_client_header(): Fix compiler warning.
64 - cgi_send_user_manual(): Also reject requests if the user-manual
65 directive specifies a https:// URL. Previously Privoxy would try and
66 fail to open a local file.
68 - General improvements:
69 - Log the TLS version and the the cipher when debug 2 is enabled.
70 - ssl_send_certificate_error(): Respect HEAD requests by not sending a body.
71 - ssl_send_certificate_error(): End the body with a single new line.
72 - serve(): Increase the chances that the host is logged when closing
74 - handle_established_connection(): Add parentheses to clarify an expression
75 Suggested by: David Binderman
76 - continue_https_chat(): Explicitly unset CSP_FLAG_CLIENT_CONNECTION_KEEP_ALIVE
77 if process_encrypted_request() fails. This makes it more obvious that the
78 connection will not be reused. Previously serve() relied on
79 CSP_FLAG_SERVER_CONTENT_LENGTH_SET and CSP_FLAG_CHUNKED being unset.
80 Inspired by a patch from Joshua Rogers (Opera).
81 - decompress_iob(): Add periods to a couple of log messages
82 - Terminate the body of the HTTP snipplets with a single new line
84 - configure: Add --with-assertions option and only enable assertions
86 - windows build: Use --with-brotli and --with-mbedtls by default and
87 enable dynamic error checking.
88 - gif_deanimate(): Confirm we've got an image before trying to write it
89 Saves a pointless buf_copy() call.
90 - OpenSSL ssl_store_cert(): Remove a superfluous space before the serial number.
92 - Action file improvements:
93 - Disable fast-redirects for .golem.de/
94 - Unblock requests to adri*.
95 - Block requests for trc*.taboola.com/
96 - Disable fast-redirects for .linkedin.com/
98 - Filter file improvements:
99 - Make the second pcrs job of the img-reorder filter greedy again.
100 The ungreedy version broke the img tags on:
101 https://bulk.fefe.de/scalability/.
103 - Privoxy-Log-Parser:
104 - Highlight a few more messages.
105 - Clarify the --statistics output. The shown "Reused connections"
106 are server connections so name them appropriately.
107 - Bump version to 0.9.3.
109 - Privoxy-Regression-Test:
110 - Add the --check-bad-ssl option to the --help output.
111 - Bump version to 0.7.3.
114 - Add pushing the created tag to the release steps in the developer manual.
115 - Clarify that 'debug 32768' should be used in addition to the other debug
116 directives when reporting problems.
117 - Add a 'Third-party licenses and copyrights' section to the user manual.
