Synopsis :

The remote Ubuntu host is missing one or more security-related

Description :

It was discovered that an integer overflow error existed in the SCSI
generic (sg) driver in the Linux kernel. A local attacker with write
permission to a SCSI generic device could use this to cause a denial
of service (system crash) or potentially escalate their privileges.

Marc-Andre Lureau discovered that the vhost driver did not properly
release the userspace provided log file descriptor. A privileged
attacker could use this to cause a denial of service (resource
exhaustion). (CVE-2015-6252)

It was discovered that the Linux kernel's perf subsystem did not bound
callchain backtraces on PowerPC 64. A local attacker could use this to
cause a denial of service. (CVE-2015-6526).

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.

Update the affected packages.
