Summary
Libyal libesedb through 20260704 contains a heap out-of-bounds read in libesedb_record_get_multi_value() caused by unbounded multi-value offset tables (CWE-125). If a user processes a crafted ESE/EDB database with esedbexport, an attacker who supplies that database can crash the application or expose up to about 32 KiB of adjacent heap memory. The references link to an exploit.
