    Debian Bug     :

    Multiple security issues were discovered in jq, a command-line JSON
    processor, which could result in denial of service or potentially the
    execution of arbitrary code when processing untrusted input.

    This update additionally addresses three issues for which no CVE has been
    assigned: GHSA-ggc9-rpv2-xgpm, GHSA-gvwx-xj9r-3frq and GHSA-gf4g-95wj-4q4r.

    Two changes in behaviour follow from the fixes above. An operation whose
    result would exceed the internal string length limit, such as repeating
    or escaping a very large string, now terminates with the error String
    too long instead of returning a truncated result. A comparison or
    containment check on a deeply nested value now reports an error rather
    than recursing until the stack is exhausted. Filters relying on the
    previous behaviour will report an error where they previously appeared
    to succeed.

    For the stable distribution (trixie), these problems have been fixed in
    version 1.7.1-6+deb13u3.

    We recommend that you upgrade your jq packages.

    For the detailed security status of jq please refer to
    its security tracker page at:
