Security update for jq
Severity
Moderate
Notes
Title of the patch: Security update for jq
Description of the patch: This update for jq fixes the following issues Security issues fixed: - CVE-2025-9403: reacheable assertion in `run_jq_tests` can lead to program termination when processing malformed JSON input containing invalid Unicode escape sequences (bsc#1248600). - CVE-2026-32316: integer overflow within the `jvp_string_append()` and `jvp_string_copy_replace_bad` functions can lead to heap buffer overflow when evaluating untrusted jq queries (bsc#1262044). - CVE-2026-33947: unbounded recursion in functions `jv_setpath()`, `jv_getpath()`, and `delpaths_sorted()` can lead to excessive resource consumption when processing crafted JSON input (bsc#1262069). - CVE-2026-33948: improper handling of buffer sizes via `strlen()` instead of `fgets()` in CLI input parsing allows validation bypass via embedded NUL bytes (bsc#1262043). - CVE-2026-39956: missing runtime type checks in `_strindices` and `jv_string_indexes()` can lead to a crash when evaluating untrusted jq filters against a release build (bsc#1262070). - CVE-2026-39979: incorrect processing of non-nul-terminated counted buffers in `jv_parse_sized` can lead to an out-of-bounds read when processing malformed JSON (bsc#1262071). - CVE-2026-40164: use of `MurmurHash3` with a hardcoded seed allows pre-computation of key collisions and can lead to a denial of service via resource exhaustion when processing crafted JSON objects (bsc#1262072). Other updates and bugfixes: - spec: add `--enable-pthread-tls` to configure invocation.

An integer overflow vulnerability exists through version 1.8.1 within the jvp_string_append() and jvp_string_copy_replace_bad functions, where concatenating strings with a combined length exceeding 2^31 bytes causes a 32-bit unsigned integer overflow in the buffer allocation size calculation, resulting in a drastically undersized heap buffer. Subsequent memory copy operations then write the full string data into this undersized buffer, causing a heap buffer overflow classified as CWE-190 (Integer Overflow) leading to CWE-122 (Heap-based Buffer Overflow). Any system evaluating untrusted jq queries is affected, as an attacker can crash the process or potentially achieve further exploitation through heap corruption by crafting queries that produce extremely large strings. The root cause is the absence of string size bounds checking, unlike arrays and objects which already have size limits.

In versions 1.8.1 and below, functions jv_setpath(), jv_getpath(), and delpaths_sorted() in jq\u0027s src/jv_aux.c use unbounded recursion whose depth is controlled by the length of a caller-supplied path array, with no depth limit enforced. An attacker can supply a JSON document containing a flat array of ~65,000 integers (~200 KB) that, when used as a path argument by a trusted jq filter, exhausts the C call stack and crashes the process with a segmentation fault (SIGSEGV). This bypass works because the existing MAX_PARSING_DEPTH (10,000) limit only protects the JSON parser, not runtime path operations where arrays can be programmatically constructed to arbitrary lengths. The impact is denial of service (unrecoverable crash) affecting any application or service that processes untrusted JSON input through jq\u0027s setpath, getpath, or delpaths builtins.

Commits before 6374ae0bcdfe33a18eb0ae6db28493b1f34a0a5b contain a vulnerability where CLI input parsing allows validation bypass via embedded NUL bytes. When reading JSON from files or stdin, jq uses strlen() to determine buffer length instead of the actual byte count from fgets(), causing it to truncate input at the first NUL byte and parse only the preceding prefix. This enables an attacker to craft input with a benign JSON prefix before a NUL byte followed by malicious trailing data, where jq validates only the prefix as valid JSON while silently discarding the suffix. Workflows relying on jq to validate untrusted JSON before forwarding it to downstream consumers are susceptible to parser differential attacks, as those consumers may process the full input including the malicious trailing bytes.

Prior to version 1.8.2, the _strindices builtin in jq\u0027s src/builtin.c passes its arguments directly to jv_string_indexes() without verifying they are strings, and jv_string_indexes() in src/jv.c relies solely on assert() checks that are stripped in release builds compiled with -DNDEBUG. This allows an attacker to crash jq trivially with input like _strindices(0), and by crafting a numeric value whose IEEE-754 bit pattern maps to a chosen pointer, achieve a controlled pointer dereference and limited memory read/probe primitive. Any deployment that evaluates untrusted jq filters against a release build is vulnerable.

In commits before 2f09060afab23fe9390cce7cb860b10416e1bf5f, the jv_parse_sized() API in libjq accepts a counted buffer with an explicit length parameter, but its error-handling path formats the input buffer using %s in jv_string_fmt(), which reads until a NUL terminator is found rather than respecting the caller-supplied length. This means that when malformed JSON is passed in a non-NUL-terminated buffer, the error construction logic performs an out-of-bounds read past the end of the buffer. The vulnerability is reachable by any libjq consumer calling jv_parse_sized() with untrusted input, and depending on memory layout, can result in memory disclosure or process termination.

Before commit 0c7d133c3c7e37c00b6d46b658a02244fdd3c784, jq used MurmurHash3 with a hardcoded, publicly visible seed (0x432A9843) for all JSON object hash table operations, which allowed an attacker to precompute key collisions offline. By supplying a crafted JSON object (~100 KB) where all keys hashed to the same bucket, hash table lookups degraded from O(1) to O(n), turning any jq expression into an O(n) operation and causing significant CPU exhaustion. This affected common jq use cases such as CI/CD pipelines, web services, and data processing scripts, and was far more practical to exploit than existing heap overflow issues since it required only a small payload.
