openSUSE Leap 15.2: 2020:2337-1 Moderate: Blosc Compression Flaw

This update for blosc fixes the following issues:

Update to version 1.20.1 boo#1179914 CVE-2020-29367:

* More saftey checks have been implemented so that potential flaws

discovered by new fuzzers in OSS-Fuzzer are fixed now

* BloscLZ updated to 2.3.0. Expect better compression ratios for faster

codecs. For details, see our new blog post:

https://blosc.org/posts/beast-release/

* Fixed the _xgetbv() collision. Thanks to Micha?? G??rny (@mgorny).

Update to version 1.19.0:

* The length of automatic blocksizes for fast codecs (lz4, blosclz) has

been incremented quite a bit (up to 256 KB) for better compression

ratios.

* The performance in modern CPUs (with at least 256 KB in L2 cache) should

be better too (for older CPUs the performance should stay roughly the

same).

* For small buffers that cannot be compressed (typically < 128 bytes),

blosc_compress() returns now a 0 (cannot compress) instead of a negative
