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)

handle certain structures. A local attacker could create malicious
requests that would hang the system, leading to a denial of service.
(CVE-2011-1082)

Neil Horman discovered that NFSv4 did not correctly handle certain
orders of operation with ACL data. A remote attacker with access to
an NFSv4 mount could exploit this to crash the system, leading to a
denial of service. (CVE-2011-1090)

certain packet structures. A remote attacker could exploit this to
crash the system, leading to a denial of service. (CVE-2011-1770)
