Nginx NJS v0.7.3 was discovered to contain a stack overflow in the function njs_default_module_loader at /src/njs/src/njs_module.c. NOTE: multiple third parties dispute this report, e.g., the behavior is only found in unreleased development code that was not part of the 0.7.2, 0.7.3, or 0.7.4 release

Nginx NJS v0.7.2 was discovered to contain a segmentation violation via njs_lvlhsh_bucket_find at njs_lvlhsh.c.

NGINX NJS 0.7.2 was discovered to contain a NULL pointer dereference via the component njs_vmcode_array at /src/njs_vmcode.c.

nginx njs 0.7.2 is vulnerable to Buffer Overflow. Type confused in Array.prototype.concat() when a slow array appended element is fast array.

nginx njs 0.7.2 is affected suffers from Use-after-free in njs_function_frame_alloc() when it try to invoke from a restored frame saved with njs_function_frame_save().

njs through 0.7.0, used in NGINX, was discovered to contain a heap use-after-free in njs_await_fulfilled.

njs through 0.7.1, used in NGINX, was discovered to contain a control flow hijack caused by a Type Confusion vulnerability in njs_promise_perform_then().

njs through 0.7.1, used in NGINX, was discovered to contain a segmentation violation via njs_object_set_prototype in /src/njs_object.c.

njs through 0.4.3, used in NGINX, allows control-flow hijack in njs_value_property in njs_value.c. NOTE: the vendor considers the issue to be "fluff" in the NGINX use case because there is no remote attack surface.

njs through 0.4.3, used in NGINX, has an out-of-bounds read in njs_json_stringify_iterator in njs_json.c.

njs through 0.4.3, used in NGINX, has an out-of-bounds read in njs_lvlhsh_level_find in njs_lvlhsh.c.

njs through 0.4.3, used in NGINX, has a use-after-free in njs_json_parse_iterator_call in njs_json.c.

njs through 0.3.3, used in NGINX, has a heap-based buffer over-read in nxt_vsprintf in nxt/nxt_sprintf.c during error handling, as demonstrated by an njs_regexp_literal call that leads to an njs_parser_lexer_error call and then an njs_parser_scope_error call.

njs through 0.3.3, used in NGINX, has a buffer over-read in nxt_utf8_decode in nxt/nxt_utf8.c. This issue occurs after the fix for CVE-2019-12207 is in place.

njs through 0.3.1, used in NGINX, has a heap-based buffer overflow in njs_function_native_call in njs/njs_function.c.

njs through 0.3.1, used in NGINX, has a heap-based buffer over-read in nxt_utf8_decode in nxt/nxt_utf8.c.

njs through 0.3.1, used in NGINX, has a heap-based buffer overflow in nxt_utf8_encode in nxt_utf8.c.

njs through 0.3.1, used in NGINX, has a heap-based buffer overflow in Array.prototype.push after a resize, related to njs_array_prototype_push in njs/njs_array.c, because of njs_array_expand size mishandling.

njs through 0.3.1, used in NGINX, has a heap-based buffer overflow in Array.prototype.splice after a resize, related to njs_array_prototype_splice in njs/njs_array.c, because of njs_array_expand size mishandling.

njs through 0.3.1, used in NGINX, has a segmentation fault in String.prototype.toBytes for negative arguments, related to nxt_utf8_next in nxt/nxt_utf8.h and njs_string_offset in njs/njs_string.c.
