Linux kernel versions 4.9+ can be forced to make very expensive calls to tcp_collapse_ofo_queue() and tcp_prune_ofo_queue() for every incoming packet which can lead to a denial of service.

F5 BIG-IP 13.0.0-13.0.1, 12.1.0-12.1.3.6, or 11.2.1-11.6.3.2 HTTPS health monitors do not validate the identity of the monitored server.

A remote attacker may be able to disrupt services on F5 BIG-IP 13.0.0-13.1.0.5, 12.1.0-12.1.3.5, 11.6.0-11.6.3.1, or 11.2.1-11.5.6 if the TMM virtual server is configured with a HTML or a Rewrite profile. TMM may restart while processing some specially prepared HTML content from the back end.

Through undisclosed methods, on F5 BIG-IP 13.0.0-13.1.0.7, 12.1.0-12.1.3.5, 11.6.0-11.6.3.1, or 11.2.1-11.5.6, adjacent network attackers can cause a denial of service for VCMP guest and host systems. Attack must be sourced from adjacent network (layer 2).

On F5 BIG-IP 14.0.0, 13.0.0-13.1.0, 12.1.0-12.1.3, or 11.5.1-11.6.3 specifically crafted HTTP responses, when processed by a Virtual Server with an associated QoE profile that has Video enabled, may cause TMM to incorrectly buffer response data causing the TMM to restart resulting in a Denial of Service.

Under certain conditions on F5 BIG-IP 13.1.0-13.1.0.5, 13.0.0, 12.1.0-12.1.3.1, 11.6.0-11.6.3.1, or 11.5.0-11.5.6, TMM may core while processing SSL forward proxy traffic.

Under certain conditions on F5 BIG-IP 13.0.0, 12.1.0-12.1.2, 11.6.0-11.6.3.1, or 11.5.0-11.5.6, TMM may core while processing SSL forward proxy traffic.

On F5 BIG-IP 13.0.0, 12.1.0-12.1.2, 11.6.0-11.6.3.1, or 11.2.1-11.5.6 a domain name cached within the DNS Cache of TMM may continue to be resolved by the cache even after the parent server revokes the record, if the DNS Cache is receiving a stream of requests for the cached name.

The svpn component of the F5 BIG-IP APM client prior to version 7.1.7 for Linux and Mac OS X runs as a privileged process and can allow an unprivileged user to assume super-user privileges on the local client host. A malicious local unprivileged user may gain knowledge of sensitive information, manipulate certain data, or disrupt service.

On an F5 BIG-IP 13.0.0-13.1.0.5, 12.1.0-12.1.3.1, or 11.2.1-11.6.3.1 system configured in Appliance mode, the TMOS Shell (tmsh) may allow an administrative user to use the dig utility to gain unauthorized access to file system resources.

On F5 BIG-IP 13.0.0-13.1.0.5, 12.1.0-12.1.3.3, or 11.2.1-11.6.3.1, administrative users by way of undisclosed methods can exploit the ssldump utility to write to arbitrary file paths. For users who do not have Advanced Shell access (for example, any user when licensed for Appliance Mode), this allows more permissive file access than intended.

On F5 BIG-IP 13.0.0-13.1.0.5, 12.1.0-12.1.2, or 11.2.1-11.6.3.1, Enterprise Manager 3.1.1, BIG-IQ Centralized Management 5.0.0-5.4.0 or 4.6.0, BIG-IQ Cloud and Orchestration 1.0.0, or F5 iWorkflow 2.0.2-2.3.0, authenticated users granted TMOS Shell (tmsh) access can access objects on the file system which would normally be disallowed by tmsh restrictions. This allows for authenticated, low privileged attackers to exfiltrate objects on the file system which should not be allowed.

In F5 BIG-IP LTM, AAM, AFM, Analytics, APM, ASM, DNS, GTM, Link Controller, PEM and WebSafe software version 13.0.0, 12.1.0 - 12.1.2 and 11.5.1 - 11.6.1, an undisclosed sequence of packets, sourced from an adjacent network may cause TMM to crash.

Directory traversal vulnerability in the configuration utility in F5 BIG-IP before 12.0.0 and Enterprise Manager 3.0.0 through 3.1.1 allows remote authenticated users to access arbitrary files in the web root via unspecified vectors.

racoon/gssapi.c in IPsec-Tools 0.8.2 allows remote attackers to cause a denial of service (NULL pointer dereference and IKE daemon crash) via a series of crafted UDP requests.

The rd_build_device_space function in drivers/target/target_core_rd.c in the Linux kernel before 3.14 does not properly initialize a certain data structure, which allows local users to obtain sensitive information from ramdisk_mcp memory by leveraging access to a SCSI initiator.
