09 May 2019 — HAProxy before 1.9.7 mishandles a reload with rotated keys, which triggers use of uninitialized, and very predictable, HMAC keys. This is related to an include/types/ssl_sock.h error. HAProxy versión anterior a 1.9.7, maneja de forma incorrecta una recarga con teclas giradas, lo que desencadena el uso de las teclas HMAC sin inicializar y muy predecibles. Esto está relacionado con un fallo del archivo include/types/ssl_sock.h. • http://git.haproxy.org/?p=haproxy.git%3Ba=commit%3Bh=8ef706502aa2000531d36e4ac56dbdc7c30f718d • CWE-327: Use of a Broken or Risky Cryptographic Algorithm CWE-908: Use of Uninitialized Resource •

https://notcve.org/view.php?id=CVE-2018-20615
05 Feb 2019 — An out-of-bounds read issue was discovered in the HTTP/2 protocol decoder in HAProxy 1.8.x and 1.9.x through 1.9.0 which can result in a crash. The processing of the PRIORITY flag in a HEADERS frame requires 5 extra bytes, and while these bytes are skipped, the total frame length was not re-checked to make sure they were present in the frame.

12 Dec 2018 — An out-of-bounds read in dns_validate_dns_response in dns.c was discovered in HAProxy through 1.8.14. Due to a missing check when validating DNS responses, remote attackers might be able read the 16 bytes corresponding to an AAAA record from the non-initialized part of the buffer, possibly accessing anything that was left on the stack, or even past the end of the 8193-byte buffer, depending on the value of accepted_payload_size.

12 Dec 2018 — An issue was discovered in dns.c in HAProxy through 1.8.14. In the case of a compressed pointer, a crafted packet can trigger infinite recursion by making the pointer point to itself, or create a long chain of valid pointers resulting in stack exhaustion. Se ha descubierto un problema en dns.c en HAProxy hasta la versión 1.8.14.

25 May 2018 — Incorrect caching of responses to requests including an Authorization header in HAProxy 1.8.0 through 1.8.9 (if cache enabled) allows attackers to achieve information disclosure via an unauthenticated remote request, related to the proto_http.c check_request_for_cacheability function.

CVSS: 8.6EPSS: 31%CPEs: 5EXPL: 0CVE-2018-10184 – haproxy: Heap buffer overflow in mux_h2.c:h2_process_demux() can allow attackers to cause a denial of service
https://notcve.org/view.php?id=CVE-2018-10184
09 May 2018 — An issue was discovered in HAProxy before 1.8.8. The incoming H2 frame length was checked against the max_frame_size setting instead of being checked against the bufsize. The max_frame_size only applies to outgoing traffic and not to incoming, so if a large enough frame size is advertised in the SETTINGS frame, a wrapped frame will be defragmented into a temporary allocated buffer where the second fragment may overflow the heap by up to 16 kB. It is very unlikely that this can be exploited for code executio... • http://git.haproxy.org/?p=haproxy-1.8.git%3Ba=commit%3Bh=cd117685f0cff4f2f5577ef6a21eaae96ebd9f28 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-122: Heap-based Buffer Overflow •
