CVE-2026-31964

HTSlib is a library for reading and writing bioinformatics file formats. CRAM is a compressed format which stores DNA sequence alignment data using a variety of encodings and compression methods. While most alignment records store DNA sequence and quality values, the format also allows them to om...

CVE-2026-31963

HTSlib is a library for reading and writing bioinformatics file formats. CRAM is a compressed format which stores DNA sequence alignment data. As one method of removing redundant data, CRAM uses reference-based compression so that instead of storing the full sequence for each alignment record it...

CVE-2026-31967

HTSlib CVE-2026-31967 concerns the CRAM reader: in cram_decode_slice(), the mate reference id is not validated, which can lead to out-of-bounds reads when mapping to reference names and potentially writing invalid data into SAM records. This can leak program state information or cause a crash. Af...

CVE-2026-31966 HTSlib CRAM reader has out-of-bounds read due to improper validation of input

HTSlib is a library for reading and writing bioinformatics file formats. CRAM is a compressed format which stores DNA sequence alignment data.

CVE-2026-31966

CVE-2026-31966 affects HTSlib’s CRAM reader. The vulnerability stems from insufficient validation of the feature data series in cram_decode_seq(), allowing data to be copied from before the start or after the end of the stored reference into output buffers or the SAM MD tag. This can lead to info...

CVE-2026-31965 HTSlib CRAM reader has out-of-bounds reads due to improper validation of input

HTSlib is a library for reading and writing bioinformatics file formats. CRAM is a compressed format which stores DNA sequence alignment data. In the cramdecodeslice function called while reading CRAM records, validation of the reference id field occurred too late, allowing two out of bounds read...
