CVE-2009-4895 [MEDIUM] Linux kernel vulnerabilities
Title: Linux kernel vulnerabilities
Summary: Multiple kernel flaws.
Dan Rosenberg discovered that the RDS network protocol did not correctly
check certain parameters. A local attacker could exploit this gain root
privileges. (CVE-2010-3904)
Nelson Elhage discovered several problems with the Acorn Econet protocol
driver. A local user could cause a denial of service via a NULL pointer
dereference, escalate privileges by overflowing the kernel stack, and
assign Econet addresses to arbitrary interfaces. (CVE-2010-3848,
CVE-2010-3849, CVE-2010-3850)
Ben Hawkes discovered that the Linux kernel did not correctly filter
registers on 64bit kernels when performing 32bit system calls. On a 64bit
system, a local attacker could manipulate 32bit system calls to gain root
privileges. (CVE-2010-3301)

CVE-2010-4078 [MEDIUM] Linux kernel vulnerabilities
Title: Linux kernel vulnerabilities
Summary: Multiple kernel flaws.
Gleb Napatov discovered that KVM did not correctly check certain privileged
operations. A local attacker with access to a guest kernel could exploit
this to crash the host system, leading to a denial of service.
(CVE-2010-0435)
Dan Jacobson discovered that ThinkPad video output was not correctly access
controlled. A local attacker could exploit this to hang the system, leading
to a denial of service. (CVE-2010-3448)
It was discovered that KVM did not correctly initialize certain CPU
registers. A local attacker could exploit this to crash the system, leading
to a denial of service. (CVE-2010-3698)
Dan Rosenberg discovered that the Linux kernel TIPC implementation
contained multiple integer signedness errors. A local at

Summary: Multiple kernel flaws.
Al Viro discovered a race condition in the TTY driver. A local attacker
could exploit this to crash the system, leading to a denial of service.
(CVE-2009-4895)
Dan Rosenberg discovered that the MOVE_EXT ext4 ioctl did not correctly
check file permissions. A local attacker could overwrite append-only files,
leading to potential data loss. (CVE-2010-2066)
Dan Rosenberg discovered that the swapexit xfs ioctl did not correctly
check file permissions. A local attacker could exploit this to read from
write-only files, leading to a loss of privacy. (CVE-2010-2226)
Gael Delalleu, Rafal Wojtczuk, and Brad Spengler discovered that the memory

Summary: Multiple kernel flaws.
Gleb Napatov discovered that KVM did not correctly check certain privileged
operations. A local attacker with access to a guest kernel could exploit
this to crash the host system, leading to a denial of service.

Dave Chinner discovered that the XFS filesystem did not correctly order
inode lookups when exported by NFS. A remote attacker could exploit this to
read or write disk blocks that had changed file assignment or had become
unlinked, leading to a loss of privacy. (CVE-2010-2943)
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)

kernel: drivers/usb/serial/mos*.c: reading uninitialized stack memory
The USB subsystem in the Linux kernel before 2.6.36-rc5 does not properly initialize certain structure members, which allows local users to obtain potentially sensitive information from kernel stack memory via vectors related to TIOCGICOUNT ioctl calls, and the (1) mos7720_ioctl function in drivers/usb/serial/mos7720.c and (2) mos7840_ioctl function in drivers/usb/serial/mos7840.c.
Statement: This issue did not affect the versions of Linux kernel as shipped with Red Hat
Enterprise Linux 3, 4, and 5 as they did not include support for Moschip USB
serial port adapters.
