**Name of the Vulnerable Software and Affected Versions** HTSlib versions prior to 1.23.1 HTSlib version 1.22.2 HTSlib version 1.21.1 **Description** HTSlib is a library used for reading and writing bioinformatics file formats. A heap buffer overflow can occur when reading data encoded using the `BYTE ARRAY STOP` method due to an out-by-one error in the `cram byte array stop decode char()` function. This error allows a single attacker-controlled byte to be written beyond the allocated heap space. Exploitation of this issue could lead to program crashes, data corruption, or potentially arbitrary code execution if a specially crafted file is opened. **Recommendations** Update HTSlib to version 1.23.1 or later. Update HTSlib to version 1.22.2 or later. Update HTSlib to version 1.21.1 or later.
