-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 _______________________________________________________________________ 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. _______________________________________________________________________ References: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2013-4483 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2013-4348 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2013-4470 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2013-2015 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2013-4387 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2013-4350 _______________________________________________________________________ Updated Packages: Mandriva Business Server 1/X86_64: 3e07dbbb16fbf8343e7886d39e59d560 mbs1/x86_64/cpupower-3.4.68-1.1.mbs1.x86_64.rpm a8d76e647c25732e008d5fe0cc901b74 mbs1/x86_64/kernel-firmware-3.4.68-1.1.mbs1.noarch.rpm df7a5f41d1a57b5330ef9670e3029b45 mbs1/x86_64/kernel-headers-3.4.68-1.1.mbs1.x86_64.rpm c5e3580627b85cd13fe34f01ecd281ff mbs1/x86_64/kernel-server-3.4.68-1.1.mbs1.x86_64.rpm 191a77d39e1608ba61bedad37934ee59 mbs1/x86_64/kernel-server-devel-3.4.68-1.1.mbs1.x86_64.rpm 60757fbb2e02db7a65abb068d668bbeb mbs1/x86_64/kernel-source-3.4.68-1.mbs1.noarch.rpm 1d3d7fa9c0343a0f864888af7ae6adf2 mbs1/x86_64/lib64cpupower0-3.4.68-1.1.mbs1.x86_64.rpm 9dcc6574393b87fb14cf61dae7d1bdb6 mbs1/x86_64/lib64cpupower-devel-3.4.68-1.1.mbs1.x86_64.rpm 4e2890287eb20fe8c838201e01c2b630 mbs1/x86_64/perf-3.4.68-1.1.mbs1.src.rpm e457d243d932d91bfffc0526c61f3edd mbs1/x86_64/perf-3.4.68-1.1.mbs1.x86_64.rpm 7b16a80336ac11a7b874e698bf95faf6 mbs1/SRPMS/cpupower-3.4.68-1.1.mbs1.src.rpm 2613ea858b6691a30613bc1edc14e245 mbs1/SRPMS/kernel-firmware-3.4.68-1.1.mbs1.src.rpm 9d28c4f34a316d012fc30a864dbb6b8e mbs1/SRPMS/kernel-headers-3.4.68-1.1.mbs1.src.rpm 574f76f01511c7c33606f60be964ea95 mbs1/SRPMS/kernel-server-3.4.68-1.1.mbs1.src.rpm 3bb6f3c5e0efe45d41c169cb5a2269cf mbs1/SRPMS/kernel-source-3.4.68-1.mbs1.src.rpm 2c7c1b9db777af533334dfc3dcd43649 mbs1/SRPMS/perf-3.4.68-1.1.mbs1.src.rpm _______________________________________________________________________ To upgrade automatically use MandrivaUpdate or urpmi.
