Summary
Security update for privoxy
Notes
Title of the patch
Security update for privoxy
Description of the patch
This update for privoxy fixes the following issues:
Update to version 3.0.32:
- Security/Reliability (boo#1183129)
- ssplit(): Remove an assertion that could be triggered with a
crafted CGI request.
Commit 2256d7b4d67. OVE-20210203-0001. CVE-2021-20272
Reported by: Joshua Rogers (Opera)
- 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. CVE-2021-20273
Reported by: Joshua Rogers (Opera)
- 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. CVE-2021-20274
Reported by: Joshua Rogers (Opera)
- chunked_body_is_complete(): Prevent an invalid read of size
two.
Commit a912ba7bc9c. OVE-20210205-0001. CVE-2021-20275
Reported by: Joshua Rogers (Opera)
- 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. CVE-2021-20276
Reported by: Joshua Rogers (Opera)
- Bug fixes:
- 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)
- decompress_iob(): Prevent reading of uninitialized data.
Reported by: Joshua Rogers (Opera).
- decompress_iob(): Don't advance cur past eod when looking
for the end of the file name and comment.
- 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)
- 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).
- 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)
- log_error(): Treat LOG_LEVEL_FATAL as fatal even when --stfu is
being used while fuzzing.
Reported by: Joshua Rogers (Opera).
- Respect DESTDIR when considering whether or not to install
config files with '.new' extension.
- OpenSSL ssl_store_cert(): Fix two error messages.
- Fix a couple of format specifiers.
- Silence compiler warnings when compiling with NDEBUG.
- fuzz_server_header(): Fix compiler warning.
- fuzz_client_header(): Fix compiler warning.
- 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.
- General improvements:
- Log the TLS version and the the cipher when debug 2 is enabled.
- ssl_send_certificate_error(): Respect HEAD requests by not sending a body.
- ssl_send_certificate_error(): End the body with a single new line.
- serve(): Increase the chances that the host is logged when closing
a server socket.
- handle_established_connection(): Add parentheses to clarify an expression
Suggested by: David Binderman
- 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.
Inspired by a patch from Joshua Rogers (Opera).
- decompress_iob(): Add periods to a couple of log messages
- Terminate the body of the HTTP snipplets with a single new line
instead of '\r\n'.
- configure: Add --with-assertions option and only enable assertions
when it is used
- windows build: Use --with-brotli and --with-mbedtls by default and
enable dynamic error checking.
- gif_deanimate(): Confirm we've got an image before trying to write it
Saves a pointless buf_copy() call.
- OpenSSL ssl_store_cert(): Remove a superfluous space before the serial number.
- Action file improvements:
- Disable fast-redirects for .golem.de/
- Unblock requests to adri*.
- Block requests for trc*.taboola.com/
- Disable fast-redirects for .linkedin.com/
- Filter file improvements:
- Make the second pcrs job of the img-reorder filter greedy again.
The ungreedy version broke the img tags on:
https://bulk.fefe.de/scalability/.
- Privoxy-Log-Parser:
- Highlight a few more messages.
- Clarify the --statistics output. The shown 'Reused connections'
are server connections so name them appropriately.
- Bump version to 0.9.3.
- Privoxy-Regression-Test:
- Add the --check-bad-ssl option to the --help output.
- Bump version to 0.7.3.
- Documentation:
- Add pushing the created tag to the release steps in the developer manual.
- Clarify that 'debug 32768' should be used in addition to the other debug
directives when reporting problems.
- Add a 'Third-party licenses and copyrights' section to the user manual.

Summary
Security update for privoxy
Notes
Title of the patch
Security update for privoxy
Description of the patch
This update for privoxy fixes the following issues:
Update to version 3.0.32:
- Security/Reliability (boo#1183129)
- ssplit(): Remove an assertion that could be triggered with a
crafted CGI request.
Commit 2256d7b4d67. OVE-20210203-0001. CVE-2021-20272
Reported by: Joshua Rogers (Opera)
- 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. CVE-2021-20273
Reported by: Joshua Rogers (Opera)
- 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. CVE-2021-20274
Reported by: Joshua Rogers (Opera)
- chunked_body_is_complete(): Prevent an invalid read of size
two.
Commit a912ba7bc9c. OVE-20210205-0001. CVE-2021-20275
Reported by: Joshua Rogers (Opera)
- 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. CVE-2021-20276
Reported by: Joshua Rogers (Opera)
- Bug fixes:
- 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)
- decompress_iob(): Prevent reading of uninitialized data.
Reported by: Joshua Rogers (Opera).
- decompress_iob(): Don't advance cur past eod when looking
for the end of the file name and comment.
- 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)
- 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).
- 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)
- log_error(): Treat LOG_LEVEL_FATAL as fatal even when --stfu is
being used while fuzzing.
Reported by: Joshua Rogers (Opera).
- Respect DESTDIR when considering whether or not to install
config files with '.new' extension.
- OpenSSL ssl_store_cert(): Fix two error messages.
- Fix a couple of format specifiers.
- Silence compiler warnings when compiling with NDEBUG.
- fuzz_server_header(): Fix compiler warning.
- fuzz_client_header(): Fix compiler warning.
- 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.
- General improvements:
- Log the TLS version and the the cipher when debug 2 is enabled.
- ssl_send_certificate_error(): Respect HEAD requests by not sending a body.
- ssl_send_certificate_error(): End the body with a single new line.
- serve(): Increase the chances that the host is logged when closing
a server socket.
- handle_established_connection(): Add parentheses to clarify an expression
Suggested by: David Binderman
- 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.
Inspired by a patch from Joshua Rogers (Opera).
- decompress_iob(): Add periods to a couple of log messages
- Terminate the body of the HTTP snipplets with a single new line
instead of '\r\n'.
- configure: Add --with-assertions option and only enable assertions
when it is used
- windows build: Use --with-brotli and --with-mbedtls by default and
enable dynamic error checking.
- gif_deanimate(): Confirm we've got an image before trying to write it
Saves a pointless buf_copy() call.
- OpenSSL ssl_store_cert(): Remove a superfluous space before the serial number.
- Action file improvements:
- Disable fast-redirects for .golem.de/
- Unblock requests to adri*.
- Block requests for trc*.taboola.com/
- Disable fast-redirects for .linkedin.com/
- Filter file improvements:
- Make the second pcrs job of the img-reorder filter greedy again.
The ungreedy version broke the img tags on:
https://bulk.fefe.de/scalability/.
- Privoxy-Log-Parser:
- Highlight a few more messages.
- Clarify the --statistics output. The shown 'Reused connections'
are server connections so name them appropriately.
- Bump version to 0.9.3.
- Privoxy-Regression-Test:
- Add the --check-bad-ssl option to the --help output.
- Bump version to 0.7.3.
- Documentation:
- Add pushing the created tag to the release steps in the developer manual.
- Clarify that 'debug 32768' should be used in addition to the other debug
directives when reporting problems.
- Add a 'Third-party licenses and copyrights' section to the user manual.
