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.

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.
