Description

A flaw was found in jq, a command line JSON processor. In release builds, the `_strindices` builtin function calls the `jv_string_indexes` function without checking that the arguments are actually strings. This missing validation allows an attacker who can supply non-string inputs to cause an application crash and a limited memory read.
