  script_tag(name:"insight", value:"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)

Ryan Sweat discovered that the GRO code did not correctly validate memory.
In some configurations on systems using VLANs, a remote attacker could send
specially crafted traffic to crash the system, leading to a denial of
service. (CVE-2011-1478)

It was discovered that the security fix for CVE-2010-4250 introduced a
regression. A remote attacker could exploit this to crash the system,
leading to a denial of service. (CVE-2011-1479)

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 the Stream Control Transmission Protocol (SCTP)
implementation incorrectly calculated lengths. If the net.sctp.addip_enable
variable was turned on, a remote attacker could send specially crafted
traffic to crash the system. (CVE-2011-1573)

Ryan Sweat discovered that the kernel incorrectly handled certain VLAN
packets. On some systems, a remote attacker could send specially crafted
traffic to crash the system, leading to a denial of service.
