libmspack 0.7.1 release

[Stuart Caie <kyzer%cabextract.org.uk@localhost>]

Hello all,

libmspack 0.7.1 has been released.

There are no bugfixes or new features. This release obfuscates one of 
the test files to make libmspack distribution possible.

libmspack 0.7 has been mostly unavailable for download since release.

I've investigated why, and found my ISP deletes all "virus infected" 
files detected by ClamAV. ClamAV finds BC.Legacy.Exploit.CVE_2012_1458-1 
in the libmspack 0.7 release. This signature detects CHM files with an 
LZX reset interval of zero, which ClamAV and libmspack were vulnerable 
to six years ago.

No other CVEs shared between libmspack and ClamAV have ClamAV 
signatures, as far as I know. I will continue to include test files that 
prove old libmspack vulnerabilties are fixed. I've asked someone from 
ClamAV if this legacy signature can be removed.

In the meantime, in order to ensure libmspack can be released and remain 
available, I have obfuscated the affected test file and made a new release.

libmspack can be downloaded from https://www.cabextract.org.uk/libmspack/
