CVE-2026-31969

A flaw was found in HTSlib, a library used for bioinformatics file formats. A remote attacker could exploit an out-by-one error when processing a specially crafted CRAM Compressed Reference-oriented Alignment Map file. This vulnerability can lead to a heap buffer overflow, potentially allowing fo...

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-2026-31965

A flaw was found in HTSlib, a library for reading and writing bioinformatics file formats. This vulnerability, an out-of-bounds read, occurs in the cramdecodeslice function when processing CRAM Compressed Reference-oriented Alignment Map records due to delayed validation of the reference ID field...

DEBIAN-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-2026-31967

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...
