The remote host is missing updates announced in
advisory RHSA-2007:0705.
The Linux kernel handles the basic functions of the operating system.
These new kernel packages contain fixes for the following security issues:
* a flaw in the DRM driver for Intel graphics cards that allowed a local
user to access any part of the main memory. To access the DRM functionality
a user must have access to the X server which is granted through the
graphical login. This also only affected systems with an Intel 965 or later
graphic chipset. (CVE-2007-3851, Important)
* a flaw in the VFAT compat ioctl handling on 64-bit systems that allowed a
local user to corrupt a kernel_dirent struct and cause a denial of service
(system crash). (CVE-2007-2878, Important)
* a flaw in the connection tracking support for SCTP that allowed a remote
user to cause a denial of service by dereferencing a NULL pointer.
(CVE-2007-2876, Important)
* flaw in the CIFS filesystem which could cause the umask values of a
process to not be honored. This affected CIFS filesystems where the Unix
extensions are supported. (CVE-2007-3740, Important)
* a flaw in the stack expansion when using the hugetlb kernel on PowerPC
systems that allowed a local user to cause a denial of service.
(CVE-2007-3739, Moderate)
* a flaw in the ISDN CAPI subsystem that allowed a remote user to cause a
denial of service or potential remote access. Exploitation would require
the attacker to be able to send arbitrary frames over the ISDN network to
the victim's machine. (CVE-2007-1217, Moderate)
* a flaw in the cpuset support that allowed a local user to obtain
sensitive information from kernel memory. To exploit this the cpuset
filesystem would have to already be mounted. (CVE-2007-2875, Moderate)
* a flaw in the CIFS handling of the mount option sec= that didn't enable
integrity checking and didn't produce any error message. (CVE-2007-3843,
Low)
Red Hat Enterprise Linux 5 users are advised to upgrade to these packages,
which contain backported patches to correct these issues.
Solution:
Please note that this update is available via
Red Hat Network. To use Red Hat Network, launch the Red
