 Mandriva Linux Security Advisory                         MDVSA-2013:265
 http://www.mandriva.com/en/support/security/
 _______________________________________________________________________

 Package : kernel
 Date    : November 10, 2013
 Affected: Business Server 1.0
 _______________________________________________________________________

 Problem Description:

 Multiple vulnerabilities has been found and corrected in the Linux
 kernel:
 
 The ipc_rcu_putref function in ipc/util.c in the Linux kernel before
 3.10 does not properly manage a reference count, which allows local
 users to cause a denial of service (memory consumption or system crash)
 via a crafted application (CVE-2013-4483).
 
 The skb_flow_dissect function in net/core/flow_dissector.c in the
 Linux kernel through 3.12 allows remote attackers to cause a denial
 of service (infinite loop) via a small value in the IHL field of a
 packet with IPIP encapsulation (CVE-2013-4348).
 
 The Linux kernel before 3.12, when UDP Fragmentation Offload (UFO) is
 enabled, does not properly initialize certain data structures, which
 allows local users to cause a denial of service (memory corruption and
 system crash) or possibly gain privileges via a crafted application
 that uses the UDP_CORK option in a setsockopt system call and
 sends both short and long packets, related to the ip_ufo_append_data
 function in net/ipv4/ip_output.c and the ip6_ufo_append_data function
 in net/ipv6/ip6_output.c (CVE-2013-4470).
 
 The ext4_orphan_del function in fs/ext4/namei.c in the Linux
 kernel before 3.7.3 does not properly handle orphan-list entries
 for non-journal filesystems, which allows physically proximate
 attackers to cause a denial of service (system hang) via a crafted
 filesystem on removable media, as demonstrated by the e2fsprogs
 tests/f_orphan_extents_inode/image.gz test (CVE-2013-2015).
 
 net/ipv6/ip6_output.c in the Linux kernel through 3.11.4 does not
 properly determine the need for UDP Fragmentation Offload (UFO)
 processing of small packets after the UFO queueing of a large packet,
 which allows remote attackers to cause a denial of service (memory
 corruption and system crash) or possibly have unspecified other
 impact via network traffic that triggers a large response packet
 (CVE-2013-4387).
 
 The IPv6 SCTP implementation in net/sctp/ipv6.c in the Linux kernel
 through 3.11.1 uses data structures and function calls that do not
 trigger an intended configuration of IPsec encryption, which allows
 remote attackers to obtain sensitive information by sniffing the
 network (CVE-2013-4350).
 
 The updated packages provides a solution for these security issues.
