    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.

Tenable has extracted the preceding description block directly from the Debian security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The version of jq installed on the remote Azure Linux 3.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2024-53427 advisory.

  - decNumberCopy in decNumber.c in jq through 1.7.1 does not properly consider that NaN is interpreted as     numeric, which has a resultant stack-based buffer overflow and out-of-bounds write, as demonstrated by use     of --slurp with subtraction, such as a filter of .-. when the input has a certain form of digit string     with NaN (e.g., 1 NaN123 immediately followed by many more digits). (CVE-2024-53427)

The version of Tencent Linux installed on the remote TencentOS Server 4 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the TSSA-2025:0286 advisory.

    Package updates are available for TencentOS Server 4 that fix the following vulnerabilities:

    CVE-2024-53427:

The remote Ubuntu 22.04 LTS / 24.04 LTS / 25.04 host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-7657-1 advisory.

    It was discovered that jq incorrectly handled certain values when parsing JSON data. A remote attacker     could possibly use this issue to cause jq to crash, resulting in a denial of service. (CVE-2024-23337)

    It was discovered that jq incorrectly handled NaN values when parsing JSON data. A remote attacker could     possibly use this issue to cause jq to crash, resulting in a denial of service. This issue only affected     Ubuntu 24.04 LTS, and Ubuntu 25.04. (CVE-2024-53427)

    It was discovered that jq incorrectly handled certain values when parsing JSON data. A remote attacker     could use this issue to cause jq to crash, resulting in a denial of service, or possibly execute arbitrary     code. (CVE-2025-48060)

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

  - jq is a command-line JSON processor. In versions up to and including 1.7.1, an integer overflow arises
    when assigning value using an index of 2147483647, the signed integer limit. This causes a denial of
    service. Commit de21386681c0df0104a99d9d09db23a9b2a78b1e contains a patch for the issue. (CVE-2024-23337)

  - decNumberCopy in decNumber.c in jq through 1.7.1 does not properly consider that NaN is interpreted as
    numeric, which has a resultant stack-based buffer overflow and out-of-bounds write, as demonstrated by use
    of --slurp with subtraction, such as a filter of .-. when the input has a certain form of digit string
    with NaN (e.g., "1 NaN123" immediately followed by many more digits). (CVE-2024-53427)

  - jq is a command-line JSON processor. In versions up to and including 1.7.1, a heap-buffer-overflow is
    present in function `jv_string_vfmt` in the jq_fuzz_execute harness from oss-fuzz. This crash happens on
    file jv.c, line 1456 `void* p = malloc(sz);`. As of time of publication, no patched versions are
    available. (CVE-2025-48060)

It is, therefore, affected by a vulnerability as referenced in the ALAS2023-2025-919 advisory.
