njs through 0.4.3
CVE-2020-24347
5.5 - Medium
- August 13, 2020
njs through 0.4.3, used in NGINX, has an out-of-bounds read in njs_lvlhsh_level_find in njs_lvlhsh.c.

Dangling pointer
NGINX before 1.17.7, with certain error_page configurations
CVE-2019-20372
5.3 - Medium
- January 09, 2020
NGINX before 1.17.7, with certain error_page configurations, allows HTTP request smuggling, as demonstrated by the ability of an attacker to read unauthorized web pages in environments where NGINX is being fronted by a load balancer.
HTTP Request Smuggling
Some HTTP/2 implementations are vulnerable to window size manipulation and stream prioritization manipulation
CVE-2019-9511
7.5 - High
- August 13, 2019
Some HTTP/2 implementations are vulnerable to window size manipulation and stream prioritization manipulation, potentially leading to a denial of service. The attacker requests a large amount of data from a specified resource over multiple streams. They manipulate window size and stream priority to force the server to queue the data in 1-byte chunks. Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both.
Allocation of Resources Without Limits or Throttling
Some HTTP/2 implementations are vulnerable to resource loops, potentially leading to a denial of service
CVE-2019-9513
7.5 - High
- August 13, 2019
Some HTTP/2 implementations are vulnerable to resource loops, potentially leading to a denial of service. The attacker creates multiple request streams and continually shuffles the priority of the streams in a way that causes substantial churn to the priority tree. This can consume excess CPU.
Some HTTP/2 implementations are vulnerable to a header leak, potentially leading to a denial of service
CVE-2019-9516
6.5 - Medium
- August 13, 2019
Some HTTP/2 implementations are vulnerable to a header leak, potentially leading to a denial of service. The attacker sends a stream of headers with a 0-length header name and 0-length header value, optionally Huffman encoded into 1-byte or greater headers. Some implementations allocate memory for these headers and keep the allocation alive until the session dies. This can consume excess memory.
Allocation of Resources Without Limits or Throttling
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
CVE-2019-13617
6.5 - Medium
- July 16, 2019
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.
Out-of-bounds Read
njs through 0.3.3, used in NGINX, has a buffer over-read in nxt_utf8_decode in nxt/nxt_utf8.c
CVE-2019-13067
9.8 - Critical
- June 30, 2019
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.
