If an application encounters a fatal protocol error and then calls SSL_shutdown() twice (once to send a close_notify, and once to receive one) then OpenSSL can respond differently to the calling application if a 0 byte record is received with invalid padding compared to if a 0 byte record is received with an invalid…

Cross-site scripting (XSS) vulnerability in F5 BIG-IP Access Policy Manager (APM) 11.5.x and 11.6.x Admin Web UI.

On BIG-IP 11.5.1-11.6.3.2, 12.1.3.4-12.1.3.7, 13.0.0 HF1-13.1.1.1, and 14.0.0-14.0.0.2, Multi-Path TCP (MPTCP) does not protect against multiple zero length DATA_FINs in the reassembly queue, which can lead to an infinite loop in some circumstances.

On BIG-IP 11.5.1-11.5.4, 11.6.1, and 12.1.0, a virtual server configured with a Client SSL profile may be vulnerable to a chosen ciphertext attack against CBC ciphers. When exploited, this may result in plaintext recovery of encrypted messages through a man-in-the-middle (MITM) attack, despite the attacker not having…

On BIG-IP 14.1.0-14.1.0.1, TMM may restart and produce a core file when validating SSL certificates in client SSL or server SSL profiles.

An issue was discovered in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.32. It is a heap-based buffer overflow in _bfd_archive_64_bit_slurp_armap in archive64.c.

In Bootstrap before 3.4.1 and 4.3.x before 4.3.1, XSS is possible in the tooltip or popover data-template attribute.

In the Linux kernel before 4.20.8, kvm_ioctl_create_device in virt/kvm/kvm_main.c mishandles reference counting because of a race condition, leading to a use-after-free.

On BIG-IP 14.0.0-14.0.0.2, 13.0.0-13.1.1.3, 12.1.0-12.1.3.7, and 11.6.0-11.6.3.2, a reflected Cross Site Scripting (XSS) vulnerability is present in an undisclosed page of the BIG-IP TMUI (Traffic Management User Interface) also known as the BIG-IP configuration utility.

libcurl versions from 7.36.0 to before 7.64.0 is vulnerable to a heap buffer out-of-bounds read. The function handling incoming NTLM type-2 messages (`lib/vauth/ntlm.c:ntlm_decode_type2_target`) does not validate incoming data correctly and is subject to an integer overflow vulnerability. Using that overflow, a…

On BIG-IP APM 14.0.0 to 14.0.0.4, 13.0.0 to 13.1.1.3 and 12.1.0 to 12.1.3.7, a reflected cross-site scripting (XSS) vulnerability exists in the resource information page for authenticated users when a full webtop is configured on the BIG-IP APM system.

When APM 13.0.0-13.1.x is deployed as an OAuth Resource Server, APM becomes a client application to an external OAuth authorization server. In certain cases when communication between the BIG-IP APM and the OAuth authorization server is lost, APM may not display the intended message in the failure response

A cross-site request forgery (CSRF) vulnerability in the APM webtop 11.2.1 or greater may allow attacker to force an APM webtop session to log out and require re-authentication.

On versions 11.2.1. and greater, unrestricted Snapshot File Access allows BIG-IP system's user with any role, including Guest Role, to have access and download previously generated and available snapshot files on the BIG-IP configuration utility such as QKView and TCPDumps.

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, when a virtual server using the inflate functionality to process a gzip bomb as a payload, the BIG-IP system will experience a fatal error and may cause the Traffic Management Microkernel (TMM) to produce a core file.
