High Nessus Plugin ID 87104

Synopsis

The remote SUSE host is missing one or more security updates.

Description

The SUSE Linux Enterprise 11 Service Pack 3 kernel was updated to receive various security and bugfixes.

Following security bugs were fixed :

- CVE-2015-8104: Prevent guest to host DoS caused by infinite loop in microcode via #DB exception (bsc#954404).

- CVE-2015-5307: Prevent guest to host DoS caused by infinite loop in microcode via #AC exception (bsc#953527).

- CVE-2015-7990: RDS: Verify the underlying transport exists before creating a connection, preventing possible DoS (bsc#952384).

- CVE-2015-5157: arch/x86/entry/entry_64.S in the Linux kernel on the x86_64 platform mishandled IRET faults in processing NMIs that occurred during userspace execution, which might have allowed local users to gain privileges by triggering an NMI (bsc#938706).

- CVE-2015-7872: Possible crash when trying to garbage collect an uninstantiated keyring (bsc#951440).

- CVE-2015-0272: Prevent remote DoS using IPv6 RA with bogus MTU by validating before applying it (bsc#944296).

- CVE-2015-6937: The __rds_conn_create function in net/rds/connection.c in the Linux kernel allowed local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact by using a socket that was not properly bound (bsc#945825).

- CVE-2015-6252: The vhost_dev_ioctl function in drivers/vhost/vhost.c in the Linux kernel allowed local users to cause a denial of service (memory consumption) via a VHOST_SET_LOG_FD ioctl call that triggered permanent file-descriptor allocation (bsc#942367).

The update package also includes non-security fixes. See advisory for details.

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
