CVE-2016-0728

(https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2016-0728)

The join_session_keyring function in security/keys/process_keys.c in the Linux kernel before 4.4.1 mishandles object references in a certain error case, which allows local users to gain privileges or cause a denial of service (integer overflow and use-after-free) via crafted keyctl commands.

Response: The flaw does not exist

This problem affects Linux Kernels 3.8 and above, so SUSE Linux Enterprise 11 and older products are not affected. (https://www.suse.com/security/cve/CVE-2016-0728.html)

The RSA Authentication Manager 8.x does not use an impacted version of the OS.

CVE-2015-8787

(https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2015-8787)

The nf_nat_redirect_ipv4 function in net/netfilter/nf_nat_redirect.c in the Linux kernel before 4.4 allows remote attackers to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact by sending certain IPv4 packets to an incompletely configured interface, a related issue to CVE-2003-1604.

Response: The flaw does not exist

Problem only impacted openSUSE. (https://bugzilla.suse.com/show_bug.cgi?id=963931)

The RSA Authentication Manager 8.x does not use an impacted version of the OS.

CVE-2015-8709

(https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2015-8709)

DISPUTED ** kernel/ptrace.c in the Linux kernel through 4.4.1 mishandles uid and gid mappings, which allows local users to gain privileges by establishing a user namespace, waiting for a root process to enter that namespace with an unsafe uid or gid, and then using the ptrace system call.

Response: The flaw exists but does not add additional risk

The disputed issue involves an increase of privileges by a non-privileged local user. For the AM appliance there is only a single appliance user, a trusted administrator (as “rsaadmin” who already has root privileges). The potential impact of attacks on the system by the privileged administrator are described “the flaw exists but does not add additional risk” since there is already risk for the administrator to attack the system in much more straight forward means.
