Description

Matthew Daley reported an information leak in the floppy disk driver of the Linux kernel. An unprivileged local user could exploit this flaw to obtain potentially sensitive information from kernel memory.
(CVE-2014-1738)

Matthew Daley reported a flaw in the handling of ioctl commands by the floppy disk driver in the Linux kernel. An unprivileged local user could exploit this flaw to gain administrative privileges if the floppy disk module is loaded. (CVE-2014-1737)

A flaw was discovered in the handling of network packets when mergeable buffers are disabled for virtual machines in the Linux kernel. Guest OS users may exploit this flaw to cause a denial of service (host OS crash) or possibly gain privilege on the host OS.

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.
