F5: >> Big-Ip Local Traffic Manager >> 13.1.0 Security Vulnerabilities
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.

On F5 BIG-IP 13.1.0-13.1.0.3, 13.0.0, 12.1.0-12.1.3.3, 11.6.1-11.6.3.1, 11.5.1-11.5.5, or 11.2.1, a malformed TLS handshake causes TMM to crash leading to a disruption of service. This issue is only exposed on the data plane when Proxy SSL configuration is enabled. The control plane is not impacted by this issue.

This allows for authenticated, low privileged attackers to exfiltrate objects on the file system which should not be allowed.
