OESA-2026-2547 htslib security update

HTSlib is an implementation of a unified C library for accessing common file formats, such as SAM, CRAM and VCF, used for high-throughput sequencing data, and is the core library used by samtools and bcftools. HTSlib only depends on zlib. It is known to be compatible with gcc, g++ and clang. HTSl...

CVE-2026-31966

A flaw was found in htslib, a library for reading and writing bioinformatics file formats. Specifically, within the CRAM Compressed Reference-oriented Alignment Map decoding process, insufficient validation of feature data series could allow a remote attacker to craft malicious CRAM records. This...

CVE-2026-31963

A flaw was found in HTSlib, a library for reading and writing bioinformatics file formats. When processing CRAM Compressed Reference-oriented Alignment Map files, an out-by-one error in feature decoding can cause a heap buffer overflow. This vulnerability allows an attacker to craft a malicious...

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...

DEBIAN-CVE-2026-31969

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 BYTEARRAYSTOP method, an out-by-one error in the...

CVE-2026-31966

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-2026-31971

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-2026-31969

HTSlib CRAM decoding bug: a heap buffer overflow in cram_byte_array_stop_decode_char() when decoding BYTE_ARRAY_STOP can write an attacker-controlled byte past a heap allocation. This arises from an out-by-one check in the full output buffer. Consequence could be program crash, data/heap-structur...

CVE-2026-31965

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...

CVE-2026-31964 HTSlib CRAM decoder has a NULL Pointer Dereference

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...

DEBIAN-CVE-2026-31962

HTSlib is a library for reading and writing bioinformatics file formats. CRAM is a compressed format which stores DNA sequence alignment data. While most alignment records store DNA sequence and quality values, the format also allows them to omit this data in certain cases to save space. Due to...
