jq is a command-line JSON processor. Prior to 1.8.2,` jq --rawfile` can turn a handled oversized-string error into invalid-state reuse and a real heap out-of-bounds write in assertion-disabled builds. When jv_load_file(raw=1) reads an attacker-controlled file, it repeatedly appends file chunks to the same jv string accumulator. Once jv_string_append_buf() returns jv_invalid_with_msg("String too long"), the raw-file loop does not stop. If the file contains at least one more byte, the next loop iteration appends a new chunk to an object that is already invalid. With assertions enabled this aborts in jvp_string_ptr(). With assertions disabled, the invalid object is interpreted as a string object and ASan reports heap-buffer-overflow. This vulnerability is fixed in 1.8.2.

Anyone running jq comparisons on     attacker-controlled deeply nested JSON values, or embedding jq in a context where untrusted data can reach     the == comparison path, is affected.

    Changes for jq:

    Update to version 1.7.1:

     * Make the default background color more suitable for bright      backgrounds.
     * Allow passing the inline jq script after --.
     * Fix possible uninitialised value dereference if jq_init() fails
     * Simplify paths/0 and paths/1.
     * Reject U+001F in string literals.
     * Remove unused nref accumulator in block_bind_library.
     * Remove a bunch of unused variables, and useless assignments.
     * main.c: Remove unused EXIT_STATUS_EXACT option.
     * Actually use the number correctly casted from double to int as      index.
     * src/builtin.c: remove unnecessary jv_copy-s in      type_error/type_error2.
     * Remove undefined behavior caught by LLVM 10 UBSAN.
     * Convert decnum to binary64 (double) instead of decimal64.
     This makes jq behave like the JSON specification suggests and      more similar to other languages.
     * Fix memory leaks on invalid input for ltrimstr/1 and      rtrimstr/1.
     * Fix memory leak on failed get for setpath/2.
     * Fix nan from json parsing also for nans with payload that      start with 'n'.
     * Allow carriage return characters in comments.
     * Generate links in the man page.
     * Add extern C for C++.
     * Make object key color configurable using JQ_COLORS environment      variable.
     * Change the default color of null to Bright Black.
     * Respect NO_COLOR environment variable to disable color output.
     * Improved --help output. Now mentions all options and nicer      order.
     * Fix multiple issues of exit code using --exit-code/-e option.
     * Add --raw-output0 for NUL (zero byte) separated output.
     * Fix assert crash and validate JSON for --jsonarg.
     * Remove deprecated --argfile option.
     * Use decimal number literals to preserve precision. Comparison      operations respects precision but arithmetic operations might      truncate.
     * Adds new builtin pick(stream) to emit a projection of the      input object or array.
     * Adds new builtin debug(msgs) that works like debug but applies      a filter on the input before writing to stderr.
     * Adds new builtin scan($re; $flags). Was documented but not      implemented.
     * Adds new builtin abs to get absolute value. This potentially      allows the literal value of numbers to be preserved as length      and fabs convert to float.
     * Allow if without else-branch. When skipped the else-branch      will be . (identity).
     * Allow use of $binding as key in object literals.
     * Allow dot between chained indexes when using .['index']
     * Allow dot for chained value iterator .[], .[]?
     * Fix try/catch catches more than it should.
     * Speed up and refactor some builtins, also remove      scalars_or_empty/0.
     * Now halt and halt_error exit immediately instead of continuing      to the next input.
     * Fix issue converting string to number after previous convert      error.
     * Fix issue representing large numbers on some platforms causing      invalid JSON output.
     * Fix deletion using assigning empty against arrays.
     * Allow keywords to be used as binding name in more places.
     * Allow using nan as NaN in JSON.
     * Expose a module's function names in modulemeta.
     * Fix contains/1 to handle strings with NUL.
     * Fix stderr/0 to output raw text without any decoration.
     * Fix nth/2 to emit empty on index out of range.
     * Fix implode to not assert and instead replace invalid unicode      codepoints.
     * Fix indices/1 and rindex/1 in case of overlapping matches in      strings.
     * Fix sub/3 to resolve issues involving global search-and-replace      (gsub) operations.
     * Fix empty regular expression matches.
     * Fix overflow exception of the modulo operator.
     * Fix string multiplication by 0 (and less than 1) to emit empty      string.
     * Fix segfault when using libjq and threads.
     * Fix constant folding of division and reminder with zero      divisor.
     * Fix error/0, error/1 to throw null error.
     * Simpler and faster transpose.
     * Simple and efficient implementation of walk/1.
     * Remove deprecated filters leaf_paths, recurse_down.

    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.

    jq --rawfile invalid-state reuse after String too long causes heap-buffer-overflow (CVE-2026-49839)

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

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

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - jq is a command-line JSON processor. Prior to 1.8.2,` jq --rawfile` can turn a handled oversized-string     error into invalid-state reuse and a real heap out-of-bounds write in assertion-disabled builds. When     jv_load_file(raw=1) reads an attacker-controlled file, it repeatedly appends file chunks to the same jv     string accumulator. Once jv_string_append_buf() returns jv_invalid_with_msg(String too long), the raw-     file loop does not stop. If the file contains at least one more byte, the next loop iteration appends a     new chunk to an object that is already invalid. With assertions enabled this aborts in jvp_string_ptr().
    With assertions disabled, the invalid object is interpreted as a string object and ASan reports heap-     buffer-overflow. This vulnerability is fixed in 1.8.2. (CVE-2026-49839)

Note that Nessus relies on the presence of the package as reported by the vendor.
