Affected Products:
SUSE Linux Enterprise Real Time Extension 11-SP4
______________________________________________________________________________
An update that solves 7 vulnerabilities and has 59 fixes is
now available.
Description:
The SUSE Linux Enterprise 11 SP4 Realtime kernel was updated to version
3.0.101.rt130-45.1 to receive various security and bugfixes.
Following security bugs were fixed:
* CVE-2015-6252: Possible file descriptor leak for each
VHOST_SET_LOG_FDcommand issued, this could eventually wasting available
system resources and creating a denial of service (bsc#942367).
* CVE-2015-5707: Possible integer overflow in the calculation of total
number of pages in bio_map_user_iov() (bsc#940338).
* CVE-2015-5364: The (1) udp_recvmsg and (2) udpv6_recvmsg functions in
the Linux kernel before 4.0.6 do not properly consider yielding a
processor, which allowed remote attackers to cause a denial of service
(system hang) via incorrect checksums within a UDP packet flood
(bnc#936831).
* CVE-2015-5366: The (1) udp_recvmsg and (2) udpv6_recvmsg functions in
the Linux kernel before 4.0.6 provide inappropriate -EAGAIN return
values, which allowed remote attackers to cause a denial of service
(EPOLLET epoll application read outage) via an incorrect checksum in a
UDP packet, a different vulnerability than CVE-2015-5364 (bnc#936831).
* CVE-2015-1420: Race condition in the handle_to_path function in
fs/fhandle.c in the Linux kernel through 3.19.1 allowed local users to
bypass intended size restrictions and trigger read operations on
additional memory locations by changing the handle_bytes value of a file
handle during the execution of this function (bnc#915517).
* CVE-2015-4700: The bpf_int_jit_compile function in
arch/x86/net/bpf_jit_comp.c in the Linux kernel before 4.0.6 allowed
local users to cause a denial of service (system crash) by creating a
packet filter and then loading crafted BPF instructions that trigger
late convergence by the JIT compiler (bnc#935705).
* CVE-2015-5697: The get_bitmap_file function in drivers/md/md.c in the
Linux kernel before 4.1.6 does not initialize a certain bitmap data
structure, which allows local users to obtain sensitive information from
kernel memory via a GET_BITMAP_FILE ioctl call. (bnc#939994)
