SynopsisThe remote Ubuntu host is missing one or more security-related patches.
DescriptionMathias Krause discovered an information leak in the Linux kernel's ISO 9660 CDROM file system driver. A local user could exploit this flaw to examine some of the kernel's heap memory. (CVE-2012-6549)
Mathias Krause discovered a flaw in xfrm_user in the Linux kernel. A local attacker with NET_ADMIN capability could potentially exploit this flaw to escalate privileges. (CVE-2013-1826)
A buffer overflow was discovered in the Linux Kernel's USB subsystem for devices reporting the cdc-wdm class. A specially crafted USB device when plugged-in could cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2013-1860)
An information leak was discovered in the Linux kernel's /dev/dvb device. A local user could exploit this flaw to obtain sensitive information from the kernel's stack memory. (CVE-2013-1928)
An information leak in the Linux kernel's dcb netlink interface was discovered. A local user could obtain sensitive information by examining kernel stack memory. (CVE-2013-2634).
Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
