CVE-2016-8658

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).
