Multiple vulnerabilities in jq can cause process crashes due to unbounded or uncontrolled recursion, heap out-of-bounds writes, and buffer overruns on 32-bit systems. These issues include stack exhaustion from recursive object merges and module loading, a heap corruption bug triggered by --rawfile with oversized strings, and an integer overflow leading to buffer overrun.

jq is a command-line JSON processor. Prior to 1.8.2, comparing two sufficiently deeply nested arrays with the == operator exhausts the C stack on jq's ordinary command-line surface, resulting in denial of service via stack exhaustion (uncontrolled recursion). The crash occurs in jq's recursive structural comparison code, with the recursion repeating through jvp_array_equal() and jv_equal() in src/jv.c when comparing deeply nested arrays; a nearby sort comparator path through jv_cmp() in src/jv_aux.c overflows the stack at a larger nesting depth from the same missing recursion guard. 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. This vulnerability is fixed in 1.8.2.

jq is a command-line JSON processor. Prior to 1.8.2, on 32bit system, jvp_string_append has a chance of integer/multiple overflowing and then causing a massive buffer overrun. This vulnerability is fixed in 1.8.2.
