Ubuntu 8.04 LTS : linux vulnerabilities (USN-1189-1)

Ubuntu Security Notice (C) 2011-2014 Canonical, Inc. / NASL script (C) 2011-2014 Tenable Network Security, Inc.


Synopsis :

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

Description :

It was discovered that the /proc filesystem did not correctly handle
permission changes when programs executed. A local attacker could hold
open files to examine details about programs running with higher
privileges, potentially increasing the chances of exploiting
additional vulnerabilities. (CVE-2011-1020)

Vasiliy Kulikov discovered that the Bluetooth stack did not correctly
clear memory. A local attacker could exploit this to read kernel stack
memory, leading to a loss of privacy. (CVE-2011-1078)

Vasiliy Kulikov discovered that the Bluetooth stack did not correctly
check that device name strings were NULL terminated. A local attacker
could exploit this to crash the system, leading to a denial of
service, or leak contents of kernel stack memory, leading to a loss of
privacy. (CVE-2011-1079)

Vasiliy Kulikov discovered that bridge network filtering did not check
that name fields were NULL terminated. A local attacker could exploit
this to leak contents of kernel stack memory, leading to a loss of
privacy. (CVE-2011-1080)

Johan Hovold discovered that the DCCP network stack did not correctly
handle certain packet combinations. A remote attacker could send
specially crafted network traffic that would crash the system, leading
to a denial of service. (CVE-2011-1093)

Peter Huewe discovered that the TPM device did not correctly
initialize memory. A local attacker could exploit this to read kernel
heap memory contents, leading to a loss of privacy. (CVE-2011-1160)

Dan Rosenberg discovered that the IRDA subsystem did not correctly
check certain field sizes. If a system was using IRDA, a remote
attacker could send specially crafted traffic to crash the system or
gain root privileges. (CVE-2011-1180)

Dan Rosenberg discovered that the X.25 Rose network stack did not
correctly handle certain fields. If a system was running with Rose
enabled, a remote attacker could send specially crafted traffic to
gain root privileges. (CVE-2011-1493)

It was discovered that Bluetooth l2cap and rfcomm did not correctly
initialize structures. A local attacker could exploit this to read
portions of the kernel stack, leading to a loss of privacy.
(CVE-2011-2492)

Dan Rosenberg discovered flaws in the linux Rose (X.25 PLP) layer used
by amateur radio. A local user or a remote user on an X.25 network
could exploit these flaws to execute arbitrary code as root.
(CVE-2011-4913)

Ben Hutchings discovered several flaws in the Linux Rose (X.25 PLP)
layer. A local user or a remote user on an X.25 network could exploit
these flaws to execute arbitrary code as root. (CVE-2011-4914).

Solution :

Update the affected packages.
