Type:
security
Severity:
Important
Release date:
2026-09-16 17:28:33 UTC
Description:
- CVE-2026-70456: heap out-of-bounds write in the daemon read_args() because the post-dot argv growth path (glob_expand()/glob_match()) reserved room only for the entry being added, so a request line landing argc on exactly maxargs made the trailing argv[argc] = NULL an 8-byte write one slot past the allocation; the +1 slot is now ensured before the store
