Affected Products:

SUSE Linux Enterprise Real Time Extension 11-SP4

SUSE Linux Enterprise Debuginfo 11-SP4

______________________________________________________________________________

 

An update that solves 10 vulnerabilities and has 62 fixes

is now available.

 

Description:

 

 

The SUSE Linux Enterprise 11 SP4 Realtime kernel was updated to receive

various security and bugfixes.

 

Following security bugs were fixed:

- CVE-2015-7509: Mounting a prepared ext2 filesystem as ext4 could lead to

a local denial of service (crash) (bsc#956709).

- CVE-2015-7799: The slhc_init function in drivers/net/slip/slhc.c in the

Linux kernel did not ensure that certain slot numbers are valid, which

allowed local users to cause a denial of service (NULL pointer

dereference and system crash) via a crafted PPPIOCSMAXCID ioctl call

(bnc#949936).

- CVE-2015-8104: The KVM subsystem in the Linux kernel allowed guest OS

users to cause a denial of service (host OS panic or hang) by triggering

many #DB (aka Debug) exceptions, related to svm.c (bnc#954404).

- CVE-2015-5307: The KVM subsystem in the Linux kernel allowed guest OS

users to cause a denial of service (host OS panic or hang) by triggering

many #AC (aka Alignment Check) exceptions, related to svm.c and vmx.c

(bnc#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 allow local users to

gain privileges by triggering an NMI (bnc#937969 937970 938706 939207).

- CVE-2015-7872: The key_gc_unused_keys function in security/keys/gc.c in

the Linux kernel allowed local users to cause a denial of service (OOPS)

via crafted keyctl commands (bnc#951440).

- CVE-2015-8215: net/ipv6/addrconf.c in the IPv6 stack in the Linux kernel

did not validate attempted changes to the MTU value, which allowed

context-dependent attackers to cause a denial of service (packet loss)

via a value that is (1) smaller than the minimum compliant value or (2)

larger than the MTU of an interface, as demonstrated by a Router

Advertisement (RA) message that is not validated by a daemon, a

different vulnerability than CVE-2015-0272. NOTE: the scope of

CVE-2015-0272 is limited to the NetworkManager product. (bnc#955354).

- 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 (bnc#945825).
