F5: >> Big-Ip Application Security Manager >> 13.1.0 Security Vulnerabilities
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.

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).

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.

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.

The inode_init_owner function in fs/inode.c in the Linux kernel through 3.16 allows local users to create files with an unintended group ownership, in a scenario where a directory is SGID to a certain group and is writable by a user who is not a member of that group. Here, the non-member can trigger creation of a plain file whose group ownership is that group. The intended behavior was that the non-member can trigger creation of a directory (but not a plain file) whose group ownership is that group. The non-member can escalate privileges by making the plain file executable and SGID.

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.
