CVE-2026-111142

Description

Zziplib through 0.13.80 contains an out-of-bounds read vulnerability in zzip/mmapped.c that allows attackers to over-read heap memory via a crafted ZIP central directory. Attackers can craft an end-of-central-directory record placing the first entry near the buffer end, causing zzip_disk_entry_strdup_name to read past the buffer and crash the application.
