Ubuntu Update for Linux kernel vulnerabilities USN-1202-1
Vulnerability Insight:
Dan Rosenberg discovered that several network ioctls did not clear kernel
memory correctly. A local user could exploit this to read kernel stack
memory, leading to a loss of privacy. (CVE-2010-3296, CVE-2010-3297)
Brad Spengler discovered that stack memory for new a process was not
correctly calculated. A local attacker could exploit this to crash the
system, leading to a denial of service. (CVE-2010-3858)
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 CAN protocol on 64bit systems did not
correctly calculate the size of certain buffers. A local attacker could
exploit this to crash the system or possibly execute arbitrary code as the
root user. (CVE-2010-3874)
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 IPC structures were not correctly initialized
on 64bit systems. A local attacker could exploit this to read kernel stack
memory, leading to a loss of privacy. (CVE-2010-4073)
Dan Rosenberg discovered that multiple terminal ioctls did not correctly
initialize structure memory. A local attacker could exploit this to read
portions of kernel stack memory, leading to a loss of privacy.
(CVE-2010-4075, CVE-2010-4076, CVE-2010-4077)
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 VIA 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-2010-4082)
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 sign ...
