CVE-2026-31971

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. When reading data encoded using the BYTEARRAYLEN method, the crambytearraylendecode failed to validat...

CVE-2026-31970

HTSlib is a library for reading and writing bioinformatics file formats. GZI files are used to index block-compressed GZIP BGZF files. In the GZI loading function, bgzfindexloadhfile, it was possible to trigger an integer overflow, leading to an under- or zero-sized buffer being allocated to stor...

CVE-2026-31968

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. For the VARINT and CONST encodings, incomplete validation of the context in which the encodings were...

CVE-2026-31967

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, the value of the mate reference id field was not validated. Later use of this value, fo...

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...
