htslib: updated to 1.15.1

1.15.1

Security fix: Fixed broken error reporting in the sam_cap_mapq() function, due to a missing hts_log() parameter. Prior to this fix it was possible to abuse the log message format string by passing a specially crafted alignment record to this function.

HTSlib now uses libhtscodecs release 1.2.2. This fixes a number of bugs where invalid compressed data could trigger usage of uninitialised values.

Fixed excessive memory used by multi-threaded SAM output on long reads.

Fixed a bug where tabix would misinterpret region specifiers starting at position 0. It will also now warn if the file being indexed is supposed to be 1-based but has positions less than or equal to 0.

The VCF header parser will now issue a warning if it finds an INFO header with Type=Flag but Number not equal to 0. It will also ignore the incorrect Number so the flag can be used.
