Message-Id: <E1KVcGv-0008LC-2P@titan.mandriva.com> Date: Tue, 19 Aug 2008 19:14:01 -0600 From: security@...driva.com To: full-disclosure@...ts.grok.org.uk Subject: [ MDVSA-2008:174 ] kernel -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 _______________________________________________________________________ Mandriva Linux Security Advisory MDVSA-2008:174 http://www.mandriva.com/security/ _______________________________________________________________________ Package : kernel Date : August 19, 2008 Affected: Corporate 4.0 _______________________________________________________________________ Problem Description: Some vulnerabilities were discovered and corrected in the Linux 2.6 kernel: Linux kernel before 2.6.22.17, when using certain drivers that register a fault handler that does not perform range checks, allows local users to access kernel memory via an out-of-range offset. (CVE-2008-0007) The asn1 implementation in (a) the Linux kernel 2.4 before 2.4.36.6 and 2.6 before 2.6.25.5, as used in the cifs and ip_nat_snmp_basic modules; and (b) the gxsnmp package; does not properly validate length values during decoding of ASN.1 BER data, which allows remote attackers to cause a denial of service (crash) or execute arbitrary code via (1) a length greater than the working buffer, which can lead to an unspecified overflow; (2) an oid length of zero, which can lead to an off-by-one error; or (3) an indefinite length for a primitive encoding. (CVE-2008-1673) Linux kernel 2.6.18, and possibly other versions, when running on AMD64 architectures, allows local users to cause a denial of service (crash) via certain ptrace calls. (CVE-2008-1615) Memory leak in the ipip6_rcv function in net/ipv6/sit.c in the Linux kernel before 2.6.25.3 allows remote attackers to cause a denial of service (memory consumption) via network traffic to a Simple Internet Transition (SIT) tunnel interface, related to the pskb_may_pull and kfree_skb functions, and management of an skb reference count. (CVE-2008-2136) Integer overflow in the sctp_getsockopt_local_addrs_old function in net/sctp/socket.c in the Stream Control Transmission Protocol (sctp) functionality in the Linux kernel before 2.6.25.9 allows local users to cause a denial of service (resource consumption and system outage) via vectors involving a large addr_num field in an sctp_getaddrs_old data structure. (CVE-2008-2826) arch/x86_64/lib/copy_user.S in the Linux kernel before 2.6.19 on some AMD64 systems does not erase destination memory locations after an exception during kernel memory copy, which allows local users to obtain sensitive information. (CVE-2008-2729) To update your kernel, please follow the directions located at: http://www.mandriva.com/en/security/kernelupdate _______________________________________________________________________ References: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-0007 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-1673 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-1615 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-2136 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-2826 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-2729 _______________________________________________________________________ Updated Packages: Corporate 4.0: aca649de138ecacc1118ffeb85a8585a corporate/4.0/i586/kernel-2.6.12.36mdk-1-1mdk.i586.rpm 4fe3d387ed0da34cafd6cce37296b105 corporate/4.0/i586/kernel-BOOT-2.6.12.36mdk-1-1mdk.i586.rpm d1f4ea6bced7542e9ae13fe587550cef corporate/4.0/i586/kernel-doc-2.6.12.36mdk-1-1mdk.i586.rpm c8981c9817e8f0cb532f33ae7a7f309a corporate/4.0/i586/kernel-i586-up-1GB-2.6.12.36mdk-1-1mdk.i586.rpm 40b1b582f84d04cbbe7d80c03db8caf7 corporate/4.0/i586/kernel-i686-up-4GB-2.6.12.36mdk-1-1mdk.i586.rpm d215dccb6a76fa5f783397fddbfc6f14 corporate/4.0/i586/kernel-smp-2.6.12.36mdk-1-1mdk.i586.rpm b64cf23b05ec50253a05d190b7663ef7 corporate/4.0/i586/kernel-source-2.6.12.36mdk-1-1mdk.i586.rpm 9473bec94760af7a36c9a67714363480 corporate/4.0/i586/kernel-source-stripped-2.6.12.36mdk-1-1mdk.i586.rpm df75cfb33266eb4a18d75e367a9f0c11 corporate/4.0/i586/kernel-xbox-2.6.12.36mdk-1-1mdk.i586.rpm cb8bbb9f2daff324ec085ac80b146101 corporate/4.0/i586/kernel-xen0-2.6.12.36mdk-1-1mdk.i586.rpm d8e3b3c456c8ba162b957d22b6313b14 corporate/4.0/i586/kernel-xenU-2.6.12.36mdk-1-1mdk.i586.rpm cf443a0b3549d4868171933bb6504d03 corporate/4.0/SRPMS/kernel-2.6.12.36mdk-1-1mdk.src.rpm Corporate 4.0/X86_64: 181a597366b6c12d437148b9ba4e42da corporate/4.0/x86_64/kernel-2.6.12.36mdk-1-1mdk.x86_64.rpm 4bc50966cf92867ebe5031a271b2f792 corporate/4.0/x86_64/kernel-BOOT-2.6.12.36mdk-1-1mdk.x86_64.rpm f67a89cd2715ab7444803532d9aa9f5c corporate/4.0/x86_64/kernel-doc-2.6.12.36mdk-1-1mdk.x86_64.rpm 12c6df680e33523ab403d01202e9ffc8 corporate/4.0/x86_64/kernel-smp-2.6.12.36mdk-1-1mdk.x86_64.rpm ea697bdc33252e1b7fba82352c91b21b corporate/4.0/x86_64/kernel-source-2.6.12.36mdk-1-1mdk.x86_64.rpm 8c1d20d6bc3fb30f7b5a51f97af6419a corporate/4.0/x86_64/kernel-source-stripped-2.6.12.36mdk-1-1mdk.x86_64.rpm 454cafa0ee5243852a1ce9f56f9cfd42 corporate/4.0/x86_64/kernel-xen0-2.6.12.36mdk-1-1mdk.x86_64.rpm f52a9f3a0ff8f7f1ad7c043ca1d424c4 corporate/4.0/x86_64/kernel-xenU-2.6.12.36mdk-1-1mdk.x86_64.rpm cf443a0b3549d4868171933bb6504d03 corporate/4.0/SRPMS/kernel-2.6.12.36mdk-1-1mdk.src.rpm _______________________________________________________________________ To upgrade automatically use MandrivaUpdate or urpmi.
