On BIG-IP 15.0.0-15.0.1.1, 14.1.0-14.1.2.2, 14.0.0-14.0.1, 13.1.0-13.1.3.1, 12.1.0-12.1.5, and 11.6.0-11.6.5.1, the tmm crashes under certain circumstances when using the connector profile if a specific sequence of connections are made.

An Information Disclosure vulnerability exists in NTP 4.2.7p25 private (mode 6/7) messages via a GETRESTRICT control message, which could let a malicious user obtain sensitive information.

On BIG-IP versions 15.0.0-15.1.0, 14.0.0-14.1.2.3, 13.1.0-13.1.3.2, 12.1.0-12.1.5, and 11.5.2-11.6.5.1, BIG-IQ versions 7.0.0, 6.0.0-6.1.0, and 5.0.0-5.4.0, iWorkflow version 2.3.0, and Enterprise Manager version 3.1.1, authenticated users granted TMOS Shell (tmsh) privileges are able access objects on the file system which would normally be disallowed by tmsh restrictions. This allows for authenticated, low privileged attackers to access objects on the file system which would not normally be allowed.

On BIG-IP ASM 15.0.0-15.0.1, 14.1.0-14.1.2, 14.0.0-14.0.1, and 13.1.0-13.1.3.1, BIG-IQ 6.0.0 and 5.2.0-5.4.0, iWorkflow 2.3.0, and Enterprise Manager 3.1.1, an attacker with access to the device communication between the BIG-IP ASM Central Policy Builder and the BIG-IQ/Enterprise Manager/F5 iWorkflow will be able to set up the proxy the same way and intercept the traffic.

The BIG-IP 15.0.0-15.0.1, 14.0.0-14.1.2.2, 13.1.0-13.1.3.1, 12.1.0-12.1.5, and 11.5.1-11.6.5.1, BIG-IQ 7.0.0, 6.0.0-6.1.0, and 5.2.0-5.4.0, iWorkflow 2.3.0, and Enterprise Manager 3.1.1 configuration utility is vulnerable to Anti DNS Pinning (DNS Rebinding) attack.

By design, BIND is intended to limit the number of TCP clients that can be connected at any given time. The number of allowed connections is a tunable parameter which, if unset, defaults to a conservative value for most servers. Unfortunately, the code which was intended to limit the number of simultaneous connections contained an error which could be exploited to grow the number of simultaneous connections beyond this limit. Versions affected: BIND 9.9.0 -> 9.10.8-P1, 9.11.0 -> 9.11.6, 9.12.0 -> 9.12.4, 9.14.0. BIND 9 Supported Preview Edition versions 9.9.3-S1 -> 9.11.5-S3, and 9.11.5-S5. Versions 9.13.0 -> 9.13.7 of the 9.13 development branch are also affected. Versions prior to BIND 9.9.0 have not been evaluated for vulnerability to CVE-2018-5743.

A race condition which may occur when discarding malformed packets can result in BIND exiting due to a REQUIRE assertion failure in dispatch.c. Versions affected: BIND 9.11.0 -> 9.11.7, 9.12.0 -> 9.12.4-P1, 9.14.0 -> 9.14.2. Also all releases of the BIND 9.13 development branch and version 9.15.0 of the BIND 9.15 development branch and BIND Supported Preview Edition versions 9.11.3-S1 -> 9.11.7-S1.

In BIG-IP 15.0.0, 14.1.0-14.1.0.6, 14.0.0-14.0.0.5, 13.0.0-13.1.1.5, 12.1.0-12.1.4.1, 11.5.1-11.6.4, BIG-IQ 7.0.0, 6.0.0-6.1.0,5.2.0-5.4.0, iWorkflow 2.3.0, and Enterprise Manager 3.1.1, the Configuration utility login page may not follow best security practices when handling a malicious request.

F5 BIG-IP 15.0.0, 14.1.0-14.1.0.6, 14.0.0-14.0.0.5, 13.0.0-13.1.1.5, 12.1.0-12.1.4.1, 11.6.0-11.6.4, and 11.5.1-11.5.9 and Enterprise Manager 3.1.1 may expose sensitive information and allow the system configuration to be modified when using non-default ConfigSync settings.

On BIG-IP 11.5.2-11.6.4 and Enterprise Manager 3.1.1, REST users with guest privileges may be able to escalate their privileges and run commands with admin privileges.

In BIG-IP 15.0.0, 14.0.0-14.1.0.5, 13.0.0-13.1.1.5, 12.1.0-12.1.4.2, and 11.5.2-11.6.4, BIG-IQ 6.0.0-6.1.0 and 5.1.0-5.4.0, iWorkflow 2.3.0, and Enterprise Manager 3.1.1, authenticated users with the ability to upload files (via scp, for example) can escalate their privileges to allow root shell access from within the TMOS Shell (tmsh) interface. The tmsh interface allows users to execute a secondary program via tools like sftp or scp.

An excessive resource consumption flaw was found in the way the Linux kernel's networking subsystem processed TCP segments. If the Maximum Segment Size (MSS) of a TCP connection was set to low values, such as 48 bytes, it can leave as little as 8 bytes for the user data, which significantly increases the Linux kernel's resource (CPU, Memory, and Bandwidth) utilization. A remote attacker could use this flaw to cause a denial of service (DoS) by repeatedly sending network traffic on a TCP connection with low TCP MSS.

In BIG-IP 14.0.0-14.0.0.2, 13.0.0-13.1.0.7, 12.1.0-12.1.3.5, 11.6.1-11.6.3.2, or 11.5.1-11.5.8 or Enterprise Manager 3.1.1, malformed requests to the Traffic Management User Interface (TMUI), also referred to as the BIG-IP Configuration utility, may lead to disruption of TMUI services. This attack requires an authenticated user with any role (other than the No Access role). The No Access user role cannot login and does not have the access level to perform the attack.

In BIG-IP 13.0.0-13.1.1.1, 12.1.0-12.1.3.7, 11.6.1-11.6.3.2, or 11.5.1-11.5.8 or Enterprise Manager 3.1.1, when authenticated administrative users run commands in the Traffic Management User Interface (TMUI), also referred to as the BIG-IP Configuration utility, restrictions on allowed commands may not be enforced.

On BIG-IP 14.0.0-14.0.0.2, 13.0.0-13.1.1.1, or 12.1.0-12.1.3.7, or Enterprise Manager 3.1.1, when authenticated administrative users run commands in the Traffic Management User Interface (TMUI), also referred to as the BIG-IP Configuration utility, restrictions on allowed commands may not be enforced.

On BIG-IP 14.0.x, 13.x, 12.x, and 11.x, Enterprise Manager 3.1.1, BIG-IQ 6.x, 5.x, and 4.x, and iWorkflow 2.x, the passphrases for SNMPv3 users and trap destinations that are used for authentication and privacy are not handled by the BIG-IP system Secure Vault feature; they are written in the clear to the various configuration files.

A flaw was found in computer hardware of the Intel microprocessors related to the instruction-side TLB (Translation Lookaside Buffer) that caches translations from guest (and host) virtual addresses into physical addresses.

This is a software fix that attempts to prevent exploitation of the hardware through preventing a hacker from creating an exploitable condition

Attackers of high privilege level are able to overwrite critical system files which bypasses security controls in place to limit TMSH commands. This is possible with an administrator or resource administrator roles when granted TMSH. Resource administrator roles must have TMSH access in order to perform this attack.

In BIG-IP 14.0.0-14.0.0.2 or 13.0.0-13.1.1.1 or Enterprise Manager 3.1.1, when authenticated administrative users run commands in the Traffic Management User Interface (TMUI), also referred to as the BIG-IP Configuration utility, restrictions on allowed commands may not be enforced.

This action utilises storage space on the /var partition and when performed repeatedly causes the /var partition to be full.

A flaw was found in the Linux kernels with commit b6a2fea39318 ("mm: variable length argument support", from July 19, 2007) but without commit da029c11e6b1 ("exec:Limit arg stack to at most 75% of STKLIM", from July 7, 2017). An integer overflow in the Linux kernel's createelftables() function. A local attacker can exploit this vulnerability via a SUID-root binary and obtain full root privileges.

A stored cross-site scripting (XSS) vulnerability in the Configuration utility device name change page in BIG-IP LTM, AAM, AFM, Analytics, APM, ASM, DNS, Edge Gateway, GTM, Link Controller, PEM, PSM, WebAccelerator, WOM and WebSafe version 12.0.0 - 12.1.2, 11.4.0 - 11.6.1, and 11.2.1 allows an authenticated user to inject arbitrary web script or HTML. Exploitation requires Resource Administrator or Administrator privileges, and it could cause the Configuration utility client to become unstable.
