    CVE-2026-0708 (GCVE-0-2026-0708)

    Title
    Libucl: libucl: denial of service via embedded null byte in ucl input
    Summary
    A flaw was found in libucl. A remote attacker could exploit this by providing a specially crafted Universal Configuration Language (UCL) input that contains a key with an embedded null byte. This can cause a segmentation fault (SEGV fault) in the `ucl_object_emit` function when parsing and emitting the object, leading to a Denial of Service (DoS) for the affected system.
