New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

SynopsisThe remote Mandriva Linux host is missing one or more security updates.
DescriptionSome vulnerabilities were discovered and corrected in the Linux 2.6 kernel :
Memory leak in the appletalk subsystem in the Linux kernel 2.4.x through 188.8.131.52 and 2.6.x through 2.6.31, when the appletalk and ipddp modules are loaded but the ipddpN device is not found, allows remote attackers to cause a denial of service (memory consumption) via IP-DDP datagrams. (CVE-2009-2903)
Multiple race conditions in fs/pipe.c in the Linux kernel before 2.6.32-rc6 allow local users to cause a denial of service (NULL pointer dereference and system crash) or gain privileges by attempting to open an anonymous pipe via a /proc/*/fd/ pathname. (CVE-2009-3547)
The tcf_fill_node function in net/sched/cls_api.c in the netlink subsystem in the Linux kernel 2.6.x before 2.6.32-rc5, and 184.108.40.206 and earlier, does not initialize a certain tcm__pad2 structure member, which might allow local users to obtain sensitive information from kernel memory via unspecified vectors. NOTE: this issue exists because of an incomplete fix for CVE-2005-4881. (CVE-2009-3612)
net/unix/af_unix.c in the Linux kernel 220.127.116.11 and earlier allows local users to cause a denial of service (system hang) by creating an abstract-namespace AF_UNIX listening socket, performing a shutdown operation on this socket, and then performing a series of connect operations to this socket. (CVE-2009-3621)
Integer overflow in the kvm_dev_ioctl_get_supported_cpuid function in arch/x86/kvm/x86.c in the KVM subsystem in the Linux kernel before 18.104.22.168 allows local users to have an unspecified impact via a KVM_GET_SUPPORTED_CPUID request to the kvm_arch_dev_ioctl function.
The nfs4_proc_lock function in fs/nfs/nfs4proc.c in the NFSv4 client in the Linux kernel before 2.6.31-rc4 allows remote NFS servers to cause a denial of service (NULL pointer dereference and panic) by sending a certain response containing incorrect file attributes, which trigger attempted use of an open file that lacks NFSv4 state.
The ip_frag_reasm function in ipv4/ip_fragment.c in Linux kernel 2.6.32-rc8, and possibly earlier versions, calls IP_INC_STATS_BH with an incorrect argument, which allows remote attackers to cause a denial of service (NULL pointer dereference and hang) via long IP packets, possibly related to the ip_defrag function. (CVE-2009-1298)
