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)");
