* [2.7] closes bpo-32997: Fix REDOS in fpformat (GH-5984)Jamie Davis2018-03-062-1/+12
| | | | | | The regex to decode a number in fpformat is susceptible to catastrophic backtracking. This is a potential DOS vector if a server is using fpformat on untrusted number strings. Replace it with an equivalent non-vulnerable regex. The match behavior of the new regex is slightly different. It captures the whole integer part of the number in one group, Leading zeros are stripped off later.
* [2.7] bpo-32981: Fix catastrophic backtracking vulns (GH-5955)Benjamin Peterson2018-03-044-3/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Prevent low-grade poplib REDOS (CVE-2018-1060) The regex to test a mail server's timestamp is susceptible to catastrophic backtracking on long evil responses from the server. Happily, the maximum length of malicious inputs is 2K thanks to a limit introduced in the fix for CVE-2013-1752. A 2KB evil response from the mail server would result in small slowdowns (milliseconds vs. microseconds) accumulated over many apop calls. This is a potential DOS vector via accumulated slowdowns. Replace it with a similar non-vulnerable regex. The new regex is RFC compliant. The old regex was non-compliant in edge cases. * Prevent difflib REDOS (CVE-2018-1061) The default regex for IS_LINE_JUNK is susceptible to catastrophic backtracking. This is a potential DOS vector. Replace it with an equivalent non-vulnerable regex. Also introduce unit and REDOS tests for difflib.

* bpo-31530: fix crash when multiple threads iterate over a file, round 2 (#5060)Benjamin Peterson2018-01-021-16/+11
| | | | | | | | | | | | | | | Multiple threads iterating over a file can corrupt the file's internal readahead buffer resulting in crashes. To fix this, cache buffer state thread-locally for the duration of a file_iternext call and only update the file's internal state after reading completes. No attempt is made to define or provide "reasonable" semantics for iterating over a file on multiple threads. (Non-crashing) races are still present. Duplicated, corrupt, and missing data will happen. This was originally fixed by 6401e5671781eb217ee1afb4603cc0d1b0367ae6, which raised an exception from seek() and next() when concurrent operations were detected. Alas, this simpler solution breaks legitimate use cases such as capturing the standard streams when multiple threads are logging.
