On BIG-IP 15.0.0-15.0.1, 14.1.0-14.1.0.5, 14.0.0-14.0.0.4, and 13.1.0-13.1.1.4, the TMM process may produce a core file when an upstream server or cache sends the BIG-IP an invalid age header value.
On BIG-IP 14.1.0-14.1.0.5, 14.0.0-14.0.0.4, 13.0.0-13.1.1.4, and 12.1.0-12.1.4, undisclosed traffic sent to BIG-IP iSession virtual server may cause the Traffic Management Microkernel (TMM) to restart, resulting in a Denial-of-Service (DoS).
On BIG-IP versions 15.0.0-15.0.1, 14.1.0-14.1.2, 14.0.0-14.0.1, 13.1.0-13.1.3.1, and 12.1.0-12.1.5, under certain conditions when using custom TCP congestion control settings in a TCP profile, TMM stops processing traffic when processed by an iRule.
On BIG-IP 14.0.0-14.1.0.5, 13.0.0-13.1.2, 12.1.0-12.1.4.1, 11.5.2-11.6.4, FTP traffic passing through a Virtual Server with both an active FTP profile associated and connection mirroring configured may lead to a TMM crash causing the configured HA action to be taken.
On versions 15.0.0-15.0.1, 14.0.0-14.1.2.2, and 13.1.0-13.1.3.1, TMM may restart on BIG-IP Virtual Edition (VE) when using virtio direct descriptors and packets 2 KB or larger.
On BIG-IP 15.0.0-15.0.1, 14.1.0-14.1.2, 14.0.0-14.0.1, 13.1.0-13.1.3.1, 12.1.0-12.1.5, and 11.5.1-11.6.5.1, undisclosed traffic flow may cause TMM to restart under some circumstances.
On versions 15.0.0-15.0.1.1, 14.0.0-14.1.2.2, 13.1.0-13.1.3.1, 12.1.0-12.1.5, and 11.5.2-11.6.5.1, under certain conditions, a multi-bladed BIG-IP Virtual Clustered Multiprocessing (vCMP) may drop broadcast packets when they are rebroadcast to the vCMP guest secondary blades. An attacker can leverage the fragmented broadcast IP packets to perform any type of fragmentation-based attack.
On BIG-IP 14.1.0-14.1.0.5, 14.0.0-14.0.0.4, 13.0.0-13.1.1.4, and 12.1.0-12.1.4, an undisclosed traffic pattern sent to a BIG-IP UDP virtual server may lead to a denial-of-service (DoS).
On BIG-IP AFM 15.0.0-15.0.1, 14.0.0-14.1.2, and 13.1.0-13.1.3.1, when bad-actor detection is configured on a wildcard virtual server on platforms with hardware-based sPVA, the performance of the BIG-IP AFM system is degraded.

The Traffic Management Microkernel (TMM) in F5 BIG-IP before 11.5.4 HF3, 11.6.x before 11.6.1 HF2 and 12.x before 12.1.2 does not properly handle minimum path MTU options for IPv6, which allows remote attackers to cause a denial-of-service (DoS) through unspecified vectors.
ModSecurity 3.x through 3.0.5 mishandles excessively nested JSON objects. Crafted JSON objects with nesting tens-of-thousands deep could result in the web server being unable to service legitimate requests. Even a moderately large (e.g., 300KB) HTTP request can occupy one of the limited NGINX worker processes for minutes and consume almost all of the available CPU on the machine. Modsecurity 2 is similarly vulnerable: the affected versions include 2.8.0 through 2.9.4.

nginx 0.8.36 allows remote attackers to cause a denial of service (crash) via certain encoded directory traversal sequences that trigger memory corruption, as demonstrated using the "%c0.%c0." sequence.
The Traffic Management Microkernel (TMM) in F5 BIG-IP LTM, AAM, AFM, Analytics, APM, ASM, GTM, Link Controller, and BIG-IP PEM before 11.4.1 HF10, 11.5.x before 11.5.4, and 11.6.x before 11.6.0 HF6 and BIG-IP PSM before 11.4.1 HF10 does not properly handle TCP options, which allows remote attackers to cause a denial of service via unspecified vectors, related to the tm.minpathmtu database variable.
The default configuration of the IPsec IKE peer listener in F5 BIG-IP LTM, Analytics, APM, ASM, and Link Controller 11.2.1 before HF16, 11.4.x, 11.5.x before 11.5.4 HF2, 11.6.x before 11.6.1, and 12.x before 12.0.0 HF2; BIG-IP AAM, AFM, and PEM 11.4.x, 11.5.x before 11.5.4 HF2, 11.6.x before 11.6.1, and 12.x before 12.0.0 HF2; BIG-IP DNS 12.x before 12.0.0 HF2; BIG-IP Edge Gateway, WebAccelerator, and WOM 11.2.1 before HF16; BIG-IP GTM 11.2.1 before HF16, 11.4.x, 11.5.x before 11.5.4 HF2, and 11.6.x before 11.6.1; and BIG-IP PSM 11.4.0 through 11.4.1 improperly enables the anonymous IPsec IKE peer configuration object, which allows remote attackers to establish an IKE Phase 1 negotiation and possibly conduct brute-force attacks against Phase 2 negotiations via unspecified vectors.
Virtual servers in F5 BIG-IP systems 11.2.1 HF11 through HF15, 11.4.1 HF4 through HF10, 11.5.3 through 11.5.4, 11.6.0 HF5 through HF7, and 12.0.0, when configured with a TCP profile, allow remote attackers to cause a denial of service (Traffic Management Microkernel restart) via crafted network traffic.

Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated
Some HTTP/2 implementations are vulnerable to a settings flood, potentially leading to a denial of service. The attacker sends a stream of SETTINGS frames to the peer. Since the RFC requires that the peer reply with one acknowledgement per SETTINGS frame, an empty SETTINGS frame is almost equivalent in behavior to a ping. Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both.

Interaction between the sks-keyserver code through 1.2.0 of the SKS keyserver network, and GnuPG through 2.2.16, makes it risky to have a GnuPG keyserver configuration line referring to a host on the SKS keyserver network. Retrieving data from this network may cause a persistent denial of service, because of a Certificate Spamming Attack.
In Wireshark 3.0.0 to 3.0.1, 2.6.0 to 2.6.8, and 2.4.0 to 2.4.14, the dissection engine could crash. This was addressed in epan/packet.c by restricting the number of layers and consequently limiting recursion.
Jonathan Looney discovered that the Linux kernel default MSS is hard-coded to 48 bytes. This allows a remote peer to fragment TCP resend queues significantly more than if a larger MSS were enforced. A remote attacker could use this to cause a denial of service. This has been fixed in stable kernel releases 4.4.182, 4.9.182, 4.14.127, 4.19.52, 5.1.11, and is fixed in commits 967c05aee439e6e5d7d805e195b3a20ef5c433d6 and 5f3e2bf008c2221478101ee72f5cb4654b9fc363.
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.
Jonathan Looney discovered that the TCP retransmission queue implementation in tcp_fragment in the Linux kernel could be fragmented when handling certain TCP Selective Acknowledgment (SACK) sequences.

Note: Software versions which have reached End of Software Development (EoSD) are not evaluated.
On BIG-IP version 16.0.x before 16.0.1.1 and 15.1.x before 15.1.3, malformed HTTP/2 requests may cause an infinite loop which causes a Denial of Service for Data Plane traffic. TMM takes the configured HA action when the TMM process is aborted. There is no control plane exposure, this is a data plane issue only. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
On BIG-IP version 16.0.x before 16.0.1.2 and 15.1.x before 15.1.3, when the iRules RESOLVER::summarize command is used on a virtual server, undisclosed requests can cause an increase in Traffic Management Microkernel (TMM) memory utilization resulting in an out-of-memory condition and a denial-of-service (DoS). Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
On versions 16.0.x before 16.0.1.1, 15.1.x before 15.1.3, 14.1.x before 14.1.4, 13.1.x before 13.1.4, 12.1.x before 12.1.6, and 11.6.x before 11.6.5.3, when the BIG-IP system is buffering packet fragments for reassembly, the Traffic Management Microkernel (TMM) may consume an excessive amount of resources, eventually leading to a restart and failover event. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
Jonathan Looney discovered that the TCP_SKB_CB(skb)->tcp_gso_segs value was subject to an integer overflow in the Linux kernel when handling TCP Selective Acknowledgments (SACKs).

This has been fixed in stable kernel releases 4.4.182, 4.9.182, 4.14.127, 4.19.52, 5.1.11, and is fixed in commit 3b4929f65b0d8249f19a50245cd88ed1a2f78cff.
On BIG-IP versions 14.1.4 and 16.0.1.1, when the Traffic Management Microkernel (TMM) process handles certain undisclosed traffic, it may start dropping all fragmented IP traffic. Note: Software versions which have reached End of Software Development (EoSD) are not evaluated.
On BIG-IP Advanced WAF and BIG-IP ASM version 16.0.x before 16.0.1.2 and 15.1.x before 15.1.3 and NGINX App Protect on all versions before 3.5.0, when a cross-site request forgery (CSRF)-enabled policy is configured on a virtual server, an undisclosed HTML response may cause the bd process to terminate. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
On BIG-IP version 16.0.0-16.0.1 and 14.1.2.4-14.1.3, cooperation between malicious HTTP client code and a malicious server may cause TMM to restart and generate a core file. Note: Software versions which have reached End of Software Development (EoSD) are not evaluated.
On versions 15.0.x before 15.1.0 and 14.1.x before 14.1.4, the BIG-IP system provides an option to connect HTTP/2 clients to HTTP/1.x servers. When a client is slow to accept responses and it closes a connection prematurely, the BIG-IP system may indefinitely retain some streams unclosed. Note: Software versions which have reached End of Software Development (EoSD) are not evaluated.
On BIG-IP versions 16.0.x before 16.0.1.1, 15.1.x before 15.1.2, 14.1.x before 14.1.3.1, 13.1.x before 13.1.3.6, 12.1.x before 12.1.5.3, and 11.6.x before 11.6.5.3, Multipath TCP (MPTCP) forwarding flows may be created on standard virtual servers without MPTCP enabled in the applied TCP profile. Note: Software versions which have reached End of Software Development (EoSD) are not evaluated.
On all 7.x versions (fixed in 8.0.0), when set up for auto failover, a BIG-IQ Data Collection Device (DCD) cluster member that receives an undisclosed message may cause the corosync process to abort. This behavior may lead to a denial-of-service (DoS) and impact the stability of a BIG-IQ high availability (HA) cluster. Note: Software versions which have reached End of Software Development (EoSD) are not evaluated.
On BIG-IP versions 16.0.x before 16.0.1.1, 15.1.x before 15.1.2.1, 14.1.x before 14.1.4, 13.1.x before 13.1.3.6, 12.1.x before 12.1.5.3, and 11.6.x before 11.6.5.3, SYN flood protection thresholds are not enforced in secure network address translation (SNAT) listeners. Note: Software versions which have reached End of Software Development (EoSD) are not evaluated.
On versions 16.0.x before 16.0.1.1, 15.1.x before 15.1.2, 14.1.x before 14.1.3.1, 13.1.x before 13.1.3.5, and 12.1.x before 12.1.5.3, when the BIG-IP ASM/Advanced WAF system processes WebSocket requests with JSON payloads using the default JSON Content Profile in the ASM Security Policy, the BIG-IP ASM bd process may produce a core file. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
On BIG-IP Advanced WAF and ASM version 16.0.x before 16.0.1.1, 15.1.x before 15.1.2, 14.1.x before 14.1.3.1, 13.1.x before 13.1.3.6, and all 12.1.x versions, when the BIG-IP ASM system processes WebSocket requests with JSON payloads, an unusually large number of parameters can cause excessive CPU usage in the BIG-IP ASM bd process. Note: Software versions which have reached End of Software Development (EoSD) are not evaluated.
On version 16.x before 16.1.0, 15.1.x before 15.1.3.1, 14.1.x before 14.1.4.3, and all versions of 13.1.x, 12.1.x and 11.6.x, when BIG-IP APM performs Online Certificate Status Protocol (OCSP) verification of a certificate that contains Authority Information Access (AIA), undisclosed requests may cause an increase in memory use.

On BIG-IP version 16.0.x before 16.0.1.1, 15.1.x before 15.1.2, 14.1.x before 14.1.3.1, 13.1.x before 13.1.3.5, and all 12.1.x versions, JSON parser function does not protect against out-of-bounds memory accesses or writes. Note: Software versions which have reached End of Software Development (EoSD) are not evaluated.
On BIG-IP 13.1.0-13.1.0.7, a remote attacker using undisclosed methods against virtual servers configured with a Client SSL or Server SSL profile that has the SSL Forward Proxy feature enabled can force the Traffic Management Microkernel (tmm) to leak memory. As a result, system memory usage increases over time, which may eventually cause a decrease in performance or a system reboot due to memory exhaustion.
Under certain conditions, on F5 BIG-IP 13.0.0-13.1.0.5, 12.1.0-12.1.3.1, or 11.6.1 HF2-11.6.3.1, virtual servers configured with Client SSL or Server SSL profiles which make use of network hardware security module (HSM) functionality are exposed and impacted by this issue.
