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.
