The remote Ubuntu 14.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-2889-2 advisory.
Use-after-free vulnerability in net/unix/af_unix.c in the Linux kernel before 4.3.3 allows local users to bypass intended AF_UNIX socket permissions or cause a denial of service (panic) via crafted epoll_ctl calls. (CVE-2013-7446)
arch/x86/kvm/x86.c in the Linux kernel before 4.4 does not reset the PIT counter values during state restoration, which allows guest OS users to cause a denial of service (divide-by-zero error and host OS crash) via a zero value, related to the kvm_vm_ioctl_set_pit and kvm_vm_ioctl_set_pit2 functions.
(CVE-2015-7513)
Race condition in the rds_sendmsg function in net/rds/sendmsg.c in the Linux kernel before 4.3.3 allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact by using a socket that was not properly bound. NOTE: this vulnerability exists because of an incomplete fix for CVE-2015-6937. (CVE-2015-7990)
fs/btrfs/inode.c in the Linux kernel before 4.3.3 mishandles compressed inline extents, which allows local users to obtain sensitive pre-truncation information from a file via a clone action. (CVE-2015-8374)
The nf_nat_redirect_ipv4 function in net/netfilter/nf_nat_redirect.c in the Linux kernel before 4.4 allows remote attackers to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact by sending certain IPv4 packets to an incompletely configured interface, a related issue to CVE-2003-1604. (CVE-2015-8787)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
