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,

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-2010-2066 [MEDIUM] kernel: ext4: Make sure the MOVE_EXT ioctl can't overwrite append-only files
kernel: ext4: Make sure the MOVE_EXT ioctl can't overwrite append-only files
The mext_check_arguments function in fs/ext4/move_extent.c in the Linux kernel before 2.6.35 allows local users to overwrite an append-only file via a MOVE_EXT ioctl call that specifies this file as a donor.
Statement: This issue did not affect the version of Linux kernel as shipped with Red Hat
Enterprise Linux 3, 4 and Red Hat Enterprise MRG as they did not include support for the Ext4 filesystem. A future kernel update in Red Hat Enterprise Linux 5 will address this issue.
No detection rules found.
