Bug fixes

  • Better enforce QNAME length restrictions in the CRAM reader. HTSlib limits the length of QNAMEs (and mate QNAMEs) to 254 characters to match the maximum allowed by the BAM format. To avoid problems with handling very long names, enforcement of this limit has been moved to an earlier stage in the CRAM decoder.
    (PR #2046. Reported by Claude and Ada Logics.
    GHSA-2jx2-wm7f-rv9m)

  • Fix incorrect block pointer caching in CRAM v4 xpack and xrle codecs.
    (Commits d66a77d, c0b5037. Reported by Trail of Bits and Anthropic.
    GHSA-6q7c-m967-9v37)

  • Several undefined behaviour fixes co-authored with Team Atlanta.

    • Missing checks that xpack and xrle codecs have enough input data.
    • Possible integer overflows when checking input size for beta, xpack and xrle codecs.
    • Some errors were incorrectly ignored in the xdelta, xpack and xrle codecs.
    • Divide-by-zeros in cram_xpack_decode_char and cram_xdelta_decode.
    • Oversized shift in cram_subexp_decode.

    (PR #2025, #2026, #2046; commits 2de3ac6 to 146231c. Reported by Team Atlanta.
    GHSA-rjqv-xg3q-g423
    GHSA-hg3g-v57p-459q)

  • Bounds-check refid when loading a CRAM .crai index.
    (PR #2029. Thanks to Sidhartha Kumar.
    GHSA-28r7-prwc-hf5c)

  • Improve checks of record consitency in the BCF reader, and disallow excessively large FORMAT entries.
    (PR #2047. Reported by VulnSeeker Security Research.
    GHSA-2wm6-8hgm-7g92)

  • Improve validation of faidx index entries.
    (PR #2008.
    GHSA-4hjq-r829-8c8v)

  • Bug fix CRAM v4 CRAM_FLAG_EXPLICIT_TLEN option. (PR #1993)

  • Remove a signed overflow bug in bgzf_read_small. (PR #2013)

  • Improve SQ LN field checking. (PR #1999)

  • Fix problem that caused hfile_libcurl to fail on platforms that disable ftp in their libcurl builds. (PR #2041)

  • Small updates to fix misplaced NULL checks, remove unused variables, and ensure the package builds without warnings on newer compilers. (PR #1992, #2004, #2028)

  • In bgzip and tabix, when handling errors, don't try to access the BGZF::errcode field after calling bgzf_close() as it may no longer be valid. (PR #2035, #2042)

  • Fix some memory leaks on failing to build or load an index (PR #2049)
