Description

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 CRAM file which, when opened by a user, could lead to a program crash, data corruption, or potentially arbitrary code execution.
