Summary
xmas-elf potential out-of-bounds read with a malformed ELF file and the HashTable API.
Details

Affected versions of this crate only validated the index argument of HashTable::get_bucket and HashTable::get_chain against the input-controlled bucket_count and chain_count fields, but not against the size of the ELF section. As a result, a malformed ELF file could trigger out-of-bounds reads in a consumer of the HashTable API by setting these fields to inappropriately large values that would fall outside the relevant hash table section, and by introducing correspondingly out-of-bounds hash table indexes elsewhere in the ELF file.

Severity ?
6.9 (Medium)
