[RELEASED] Release candidates for Python 2.6.8, 2.7.3, 3.1.5, and 3.2.3
We're pleased to announce the immediate availability of release candidates for Python 2.6.8, 2.7.3, 3.1.5, and 3.2.3 . The main impetus for these releases is fixing a security issue in Python's hash based types, dict and set, as described below. Python 2.7.3 and 3.2.3 include the security patch and the normal set of bug fixes. Since Python 2.6 and 3.1 are maintained only for security issues, 2.6.8 and 3.1.5 contain only various security patches. The security issue exploits Python's dict and set implementations.

Since Python 2.6 and 3.1 are maintained only for security issues, 2.6.8 and 3.1.5 contain only various security patches. The security issue exploits Python's dict and set implementations. Carefully crafted input can lead to extremely long computation times and denials of service. [1] Python dict and set types use hash tables to provide amortized constant time operations. Hash tables require a well-distributed hash function to spread data evenly across the hash table. The security issue is that an attacker could compute thousands of keys with colliding hashes; this causes quadratic algorithmic complexity when the hash table is constructed. To alleviate the problem, the new releases add randomization to the hashing of Python's string types (bytes/str in Python 3 and str/unicode in Python 2), datetime.date, and datetime.datetime. This prevents an attacker from computing colliding keys of these types without access to the Python process. Hash randomization causes the iteration order of dicts and sets to be unpredictable and differ across Python runs. Python has never guaranteed iteration order of keys in a dict or set,...

[RELEASED] Second release candidates for Python 2.6.8, 2.7.3, 3.1.5, and 3.2.3
We're chuffed to announce the immediate availability of the second release candidates for Python 2.6.8, 2.7.3, 3.1.5, and 3.2.3. The only change from the first release candidates is the patching of an additional security hole. The security issue fixed in the second release candidates is in the expat XML parsing library. expat had the same hash security issue detailed below as Python's core types. The hashing algorithm used in the expat library is now randomized. A more thorough explanation of the "hash attack" security hole follows. The main impetus for these releases is fi...

[RELEASED] Python 3.2.4 rc 1 and Python 3.3.1 rc 1
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 On behalf of the Python development team, I am pleased to announce the first release candidates of Python 3.2.4 and 3.3.1. Python 3.2.4 will be the last regular maintenance release for the Python 3.2 series, while Python 3.3.1 is the first maintenance release for the 3.3 series. Both releases include hundreds of bugfixes. There has recently been a lot of discussion about XML-based denial of service attacks. Specifically, certain XML files can cause XML parsers, including ones in the Python stdlib, to consume gigabytes of RAM and swamp the CPU. These releases do not include any changes in Python XML code to address these issues. Interested parties should examine the defusedxml package on PyPI: https://pypi.python.org/pypi/defusedxml These are testing releases: Please consider trying them with your code and reporting any bugs you may notice to: http://bugs.python.org/ To download Python 3.2.4 or Python 3.3.1, visit: http://www.python.org/download/releases/3.2.4/ or http://www.python.org/download/releases/3.3.1/ respectively.

[RELEASED] Python 3.3.3 release candidate 1
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 On behalf of the Python development team, I'm quite happy to announce the Python 3.3.3 release candidate 1. Python 3.3.3 includes several security fixes and over 150 bug fixes compared to the Python 3.3.2 release. This release fully supports OS X 10.9 Mavericks. In particular, this release fixes an issue that could cause previous versions of Python to crash when typing in interactive mode on OS X 10.9. Python 3.3.3 also contains a new batteries-included feature for OS X users of IDLE and other Tkinter-based programs. The python.org Mac OS X 64-bit/32-bit x86-64/i386 Installer for OS X 10.6+ now includes its own builtin version of Tcl/Tk 8.5. It is no longer necessary to install a third-party version of Tcl/Tk 8.5 to workaround the problematic system versions. See http://www.python.org/download/mac/tcltk/ for more information. Python 3.3 includes a range of improvements of the 3.x series, as well as easier porting between 2.x and 3.x. In total, almost 500 API items are new or improved in Python 3.3. For a more extensive list of changes in the 3.3 series, see http://docs.python.org/3.3/whatsnew/3.3.html and for the detailed changelog of 3.3.3, see http://docs.python.org/3.3/whatsnew/changelog.html To download Python 3.3.3 rc1 visit: http://www.python.org/download/releases/3.3.3/ This is a preview release, please report any bugs to http://bugs.python.org/ T...
