  script_tag(name:"insight", value:"Goldwyn Rodrigues discovered that the OCFS2 filesystem did not correctly
clear memory when writing certain file holes. A local attacker could
exploit this to read uninitialized data from the disk, leading to a loss of
privacy. (CVE-2011-0463)

Timo Warns discovered that the LDM disk partition handling code did not
correctly handle certain values. By inserting a specially crafted disk
device, a local attacker could exploit this to gain root privileges.
(CVE-2011-1017)

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)

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)

Vasiliy Kulikov discovered that the netfilter code did not check certain
strings copied from userspace. A local attacker with netfilter access could
exploit this to read kernel memory or crash the system, leading to a denial
of service. (CVE-2011-1170, CVE-2011-1171, CVE-2011-1172, CVE-2011-2534)

Vasiliy Kulikov discovered that the Acorn Universal Networking driver did
not correctly initialize memory. A remote attacker could send specially
crafted traffic to read kernel stack memory, leading to a loss of privacy.
(CVE-2011-1173)

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)

Julien Tinnes discovered that the kernel did not correctly validate the
signal structure from tkill(). A local attacker could exploit this to send
signals to arbitrary threads, possibly bypassing expected restrictions.
(CVE-2011-1182)

Dan Rosenberg reported errors in the OSS (Open Sound System) MIDI
interface. A local attacker on non-x86 systems might be able to cause a
denial of service. (CVE-2011-1476)
