Details

Tavis Ormandy discovered that the Linux kernel did not properly implement
exception fixup. A local attacker could exploit this to crash the kernel,
leading to a denial of service. (CVE-2010-3086)

Dan Rosenberg discovered that the Linux kernel TIPC implementation
contained multiple integer signedness errors. A local attacker could
exploit this to gain root privileges. (CVE-2010-3859)

Dan Rosenberg discovered that the Linux kernel X.25 implementation
incorrectly parsed facilities. A remote attacker could exploit this to
crash the kernel, leading to a denial of service. (CVE-2010-3873)

Vasiliy Kulikov discovered that the Linux kernel X.25 implementation did
not correctly clear kernel memory. A local attacker could exploit this to
read kernel stack memory, leading to a loss of privacy. (CVE-2010-3875)

Vasiliy Kulikov discovered that the Linux kernel sockets implementation
did not properly initialize certain structures. A local attacker could
exploit this to read kernel stack memory, leading to a loss of privacy.
(CVE-2010-3876)

Nelson Elhage discovered that the Linux kernel IPv4 implementation did not
properly audit certain bytecodes in netlink messages. A local attacker
could exploit this to cause the kernel to hang, leading to a denial of
service. (CVE-2010-3880)

Dan Rosenberg discovered that the SiS video driver did not correctly clear
kernel memory. A local attacker could exploit this to read kernel stack
memory, leading to a loss of privacy. (CVE-2010-4078)

Dan Rosenberg discovered that the RME Hammerfall DSP audio interface driver
did not correctly clear kernel memory. A local attacker could exploit this
to read kernel stack memory, leading to a loss of privacy. (CVE-2010-4080,
CVE-2010-4081)

Dan Rosenberg discovered that the semctl syscall did not correctly clear
kernel memory. A local attacker could exploit this to read kernel stack
memory, leading to a loss of privacy. (CVE-2010-4083)

James Bottomley discovered that the ICP vortex storage array controller
driver did not validate certain sizes. A local attacker on a 64bit system
could exploit this to crash the kernel, leading to a denial of service.
(CVE-2010-4157)

Dan Rosenberg discovered that the Linux kernel L2TP implementation
contained multiple integer signedness errors. A local attacker could
exploit this to to crash the kernel, or possibly gain root privileges.
(CVE-2010-4160)
