CVE-2011-2699: Fernando Gont discovered that the IPv6 stack used
predictable fragment identification numbers. A remote attacker could
exploit this to exhaust network resources, leading to a denial of
service.

CVE-2011-1173: A kernel information leak via ip6_tables was fixed.

CVE-2011-1172: A kernel information leak via ip6_tables netfilter was
fixed.

CVE-2011-1171: A kernel information leak via ip_tables was fixed.

CVE-2011-1170: A kernel information leak via arp_tables was fixed.

CVE-2011-1080: A kernel information leak via netfilter was fixed.

CVE-2011-2213: The inet_diag_bc_audit function in net/ipv4/inet_diag.c
in the Linux kernel did not properly audit INET_DIAG bytecode, which
allowed local users to cause a denial of service (kernel infinite
loop) via crafted INET_DIAG_REQ_BYTECODE instructions in a netlink
message, as demonstrated by an INET_DIAG_BC_JMP instruction with a
zero yes value, a different vulnerability than CVE-2010-3880.

CVE-2011-2534: Buffer overflow in the clusterip_proc_write function in
net/ipv4/netfilter/ipt_CLUSTERIP.c in the Linux kernel might have
allowed local users to cause a denial of service or have unspecified
other impact via a crafted write operation, related to string data
that lacks a terminating '0' character.

CVE-2011-1770: Integer underflow in the dccp_parse_options function
(net/dccp/options.c) in the Linux kernel allowed remote attackers to
cause a denial of service via a Datagram Congestion Control Protocol
(DCCP) packet with an invalid feature options length, which triggered
a buffer over-read.

CVE-2011-2723: The skb_gro_header_slow function in
include/linux/netdevice.h in the Linux kernel, when Generic Receive
Offload (GRO) is enabled, reset certain fields in incorrect
situations, which allowed remote attackers to cause a denial of
service (system crash) via crafted network traffic.

CVE-2011-2898: A kernel information leak in the AF_PACKET protocol was
fixed which might have allowed local attackers to read kernel memory.

CVE-2011-4087: A local denial of service when using bridged networking
via a flood ping was fixed.

CVE-2011-2203: A NULL ptr dereference on mounting corrupt hfs
filesystems was fixed which could be used by local attackers to crash
the kernel.

CVE-2011-4081: Using the crypto interface a local user could Oops the
kernel by writing to a AF_ALG socket."
