Description
jq is a command-line JSON processor. In 1.8.1 and earlier, the jq bytecode VM-s data stack tracks its allocation size in a signed int. When the stack grows beyond ≈1 GiB (via deeply nested generator forks), the doubling arithmetic overflows. The wrapped value is passed to realloc and then used for a memmove with attacker-influenced offsets.
