Protocol Buffers v3.20.3

Java

• Refactoring java full runtime to reuse sub-message builders and prepare to migrate parsing logic from parse constructor to builder.
• Move proto wireformat parsing functionality from the private "parsing constructor" to the Builder class.
• Change the Lite runtime to prefer merging from the wireformat into mutable messages rather than building up a new immutable object before merging. This way results in fewer allocations and copy operations.
• Make message-type extensions merge from wire-format instead of building up instances and merging afterwards. This has much better performance.
• Fix TextFormat parser to build up recurring (but supposedly not repeated) sub-messages directly from text rather than building a new sub-message and merging the fully formed message into the existing field.
• This release addresses a Security Advisory for Java users

Protocol Buffers v3.20.2

C++

• Reduce memory consumption of MessageSet parsing
• This release addresses a Security Advisory for C++ and Python users

Protocol Buffers v3.20.1

PHP

• Fix building packaged PHP extension (#9727)
• Fixed composer.json to only advertise compatibility with PHP 7.0+. (#9819)

Ruby

• Disable the aarch64 build on macOS until it can be fixed. (#9816)

Other

• Fix versioning issues in 3.20.0

Protocol Buffers v3.20.1-rc1

PHP

• Fix building packaged PHP extension (#9727)

Protocol Buffers v3.20.0

2022-03-25 version 3.20.0 (C++/Java/Python/PHP/Objective-C/C#/Ruby/JavaScript)

Ruby

• Dropped Ruby 2.3 and 2.4 support for CI and releases. (#9311)
• Added Ruby 3.1 support for CI and releases (#9566).
• Message.decode/encode: Add recursion_limit option (#9218/#9486)
• Allocate with xrealloc()/xfree() so message allocation is visible to the Ruby GC. In certain tests this leads to much lower memory usage due to more frequent GC runs (#9586).
• Fix conversion of singleton classes in Ruby (#9342)

Version 4.7 - released 2021-01-10

• Fix #165: CVE-2020-25658 - Bleichenbacher-style timing oracle in PKCS#1 v1.5 decryption code
• Add padding length check as described by PKCS#1 v1.5 (Fixes #164)
• Reuse of blinding factors to speed up blinding operations. Fixes #162.
• Declare & test support for Python 3.9

Version 4.4 & 4.6 - released 2020-06-12

Version 4.4 and 4.6 are almost a re-tagged release of version 4.2. It requires Python 3.5+. To avoid older Python installations from trying to upgrade to RSA 4.4, this is now made explicit in the python_requires argument in setup.py. There was a mistake releasing 4.4 as "3.5+ only", which made it necessary to retag 4.4 as 4.6 as well.

No functional changes compared to version 4.2.

Version 4.3 & 4.5 - released 2020-06-12

Version 4.3 and 4.5 are almost a re-tagged release of version 4.0. It is the last to support Python 2.7. This is now made explicit in the python_requires argument in setup.py. Python 3.4 is not supported by this release. There was a mistake releasing 4.4 as "3.5+ only", which made it necessary to retag 4.3 as 4.5 as well.

Two security fixes have also been backported, so 4.3 = 4.0 + these two fixes.

• Choose blinding factor relatively prime to N. Thanks Christian Heimes for pointing this out.
• Reject cyphertexts (when decrypting) and signatures (when verifying) that have been modified by prepending zero bytes. This resolves CVE-2020-13757. Thanks Carnil for pointing this out.

Version 4.2 - released 2020-06-10

• Rolled back the switch to Poetry, and reverted back to using Pipenv + setup.py for dependency management. There apparently is an issue no-binary installs of packages build with Poetry. This fixes #148
• Limited SHA3 support to those Python versions (3.6+) that support it natively. The third-party library that adds support for this to Python 3.5 is a binary package, and thus breaks the pure-Python nature of Python-RSA. This should fix #147.
