jq is a command-line JSON processor. In versions up to and including 1.7.1, a heap-buffer-overflow is present in function `jv_string_vfmt` in the jq_fuzz_execute harness from oss-fuzz. This crash happens on file jv.c, line 1456 `void* p = malloc(sz);`. As of time of publication, no patched versions are available.
A flaw was found in jq, a command line JSON processor. A specially crafted input can cause a heap-based buffer over-read when formatting an empty string because it was not properly null-terminated, causing a crash and resulting in a denial of service.
It was discovered that jq incorrectly handled certain values when parsing JSON data. A remote attacker could possibly use this issue to cause jq to crash, resulting in a denial of service. It was discovered that jq incorrectly handled NaN values when parsing JSON data. A remote attacker could possibly use this issue to cause jq to crash, resulting in a denial of service.
