Affected Products:
openSUSE Leap 42.1
______________________________________________________________________________

An update that solves four vulnerabilities and has 21 fixes
is now available.

Description:

The openSUSE Leap 42.1 kernel was updated to 4.1.34, fixing bugs and
security issues.

The following security bugs were fixed:

– CVE-2016-5195: A local privilege escalation using MAP_PRIVATE was fixed,
which is reportedly exploited in the wild (bsc#1004418).
– CVE-2016-8658: Stack-based buffer overflow in the
brcmf_cfg80211_start_ap function in
drivers/net/wireless/broadcom/brcm80211/brcmfmac/cfg80211.c in the Linux
kernel allowed local users to cause a denial of service (system crash)
or possibly have unspecified other impact via a long SSID Information
Element in a command to a Netlink socket (bnc#1004462).
– CVE-2016-7039: The IP stack in the Linux kernel allowed remote attackers
to cause a denial of service (stack consumption and panic) or possibly
have unspecified other impact by triggering use of the GRO path for
large crafted packets, as demonstrated by packets that contain only VLAN
headers, a related issue to CVE-2016-8666 (bnc#1001486).
– CVE-2016-7425: The arcmsr_iop_message_xfer function in
drivers/scsi/arcmsr/arcmsr_hba.c in the Linux kernel did not restrict a
certain length field, which allowed local users to gain privileges
or cause a denial of service (heap-based buffer overflow) via an
ARCMSR_MESSAGE_WRITE_WQBUFFER control code (bnc#999932).
