Ubuntu 17.04 : linux, linux-raspi2 vulnerabilities (USN-3377-1) (Stack Clash)

Ubuntu Security Notice (C) 2017 Canonical, Inc. / NASL script (C) 2017 Tenable Network Security, Inc.


Synopsis :

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

Description :

Fan Wu and Shixiong Zhao discovered a race condition between inotify
events and vfs rename operations in the Linux kernel. An unprivileged
local attacker could use this to cause a denial of service (system
crash) or execute arbitrary code. (CVE-2017-7533)

It was discovered that the Linux kernel did not properly restrict
RLIMIT_STACK size. A local attacker could use this in conjunction with
another vulnerability to possibly execute arbitrary code.
(CVE-2017-1000365)

Li Qiang discovered that the Virtio GPU driver in the Linux kernel did
not properly free memory in some situations. A local attacker could
use this to cause a denial of service (memory consumption).
(CVE-2017-10810)

Shi Lei discovered that the RxRPC Kerberos 5 ticket handling code in
the Linux kernel did not properly verify metadata. A remote attacker
could use this to cause a denial of service (system crash) or possibly
execute arbitrary code. (CVE-2017-7482).

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.

Solution :

Update the affected packages.

Risk factor :

High / CVSS Base Score : 7.8
(CVSS2#AV:N/AC:L/Au:N/C:N/I:N/A:C)
CVSS Temporal Score : 5.8
(CVSS2#E:U/RL:OF/RC:C)
