high Nessus Plugin ID 348728

Synopsis

The remote SUSE host is missing one or more security updates.

Description

The remote SUSE Linux SLED15 / SLED_SAP15 / SLES15 / SLES_SAP15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2026:4275-1 advisory.

Security issues fixed:

- CVE-2015-8863: heap buffer overflow in tokenadd() function (bsc#976992).
- CVE-2023-50246: improper memory handling can lead to a heap buffer overflow in `decNumberToString` (bsc#1218034).
- CVE-2023-50268: stack-based buffer overflow in builds using decNumber (bsc#1218038).
- CVE-2024-53427: stack-buffer-overflow in the decNumberCopy function in decNumber.c (bsc#1238078).
- CVE-2025-9403: reachable assertion in run_jq_tests() (bsc#1248600).
- CVE-2026-33948: CLI input parsing allows validation bypass via embedded NUL bytes (bsc#1262043).
- CVE-2026-40164: predictable hash collisions can lead to a denial of service (bsc#1262072).
- CVE-2026-40612: jv_contains recurses into nested arrays/objects with no depth limit and can cause a stack overflow (bsc#1265060).
- CVE-2026-41256: embedded NUL truncates top-level jq programs loaded with -f and can lead to execution of unintended programs (bsc#1265061).
- CVE-2026-41257: integer overflow in `stack_reallocate` can lead to memory corruption and DoS (bsc#1265062).
- CVE-2026-43894: signed integer overflow in `decNumber` can lead to out-of-bounds memory write (bsc#1265070).
- CVE-2026-43895: embedded NUL bytes in import paths can lead to policy bypass and sensitive information disclosure (bsc#1265071).
- CVE-2026-43896: unbounded recursion in `jv_object_merge_recursive()` can lead to C stack exhaustion and a process crash (bsc#1265075).
- CVE-2026-44777: uncontrolled recursion in ordinary module loader when two valid modules `include` each other can lead to stack exhaustion and process crash (bsc#1265076).
- CVE-2026-47770: stack overflow in deep structural equality (bsc#1269221).
- CVE-2026-49839: `--rawfile` invalid-state reuse after `String too long` can lead to a heap buffer overflow (bsc#1269220).
- CVE-2026-54679: integer overflow in `jvp_string_append` can lead to a buffer overrun on 32-bit systems (bsc#1269390).

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.

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

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

Solution

Update the affected jq, libjq-devel and / or libjq1 packages.
