{"schemaVersion":3,"id":"CVE-2026-75818","aliases":["UBUNTU-CVE-2026-75818","DEBIAN-CVE-2026-75818"],"status":"published","duplicateOf":null,"title":null,"description":"GNU Aspell prezip-bin contains a heap-based buffer overflow vulnerability in the decompressor in prog/prezip.c. The decompressor does not properly check buffer space, so a crafted compressed file can cause out-of-bounds read and write operations on the heap. An attacker who convinces a user to process a malicious compressed file with prezip-bin can trigger memory corruption, leading to a processs crash.\n\n\n\nThis issue was fixed in
