Debian-specific: no
CVE ID : CVE-2007-3104 CVE-2007-4997 CVE-2007-5500 CVE-2007-5904
Several local and remote vulnerabilities have been discovered in the Linux
kernel that may lead to a denial of service or the execution of arbitrary
code. The Common Vulnerabilities and Exposures project identifies the
following problems:
This is an update to DSA 1428-1 which omitted a reference to CVE-2007-5904.
CVE-2007-3104
Eric Sandeen provided a backport of Tejun Heo's fix for a local denial
of service vulnerability in sysfs. Under memory pressure, a dentry
structure maybe reclaimed resulting in a bad pointer dereference causing
an oops during a readdir.
CVE-2007-4997
Chris Evans discovered an issue with certain drivers that make use of the
Linux kernel's ieee80211 layer. A remote user could generate a malicious
802.11 frame that could result in a denial of service (crash). The ipw2100
driver is known to be affected by this issue, while the ipw2200 is
believed not to be.
CVE-2007-5500
Scott James Remnant diagnosed a coding error in the implementation of
ptrace which could be used by a local user to cause the kernel to enter
an infinite loop.
CVE-2007-5904
Przemyslaw Wegrzyn discovered an issue in the CIFS filesystem that could
allow a malicious server to cause a denial of service (crash) by overflowing
a buffer.
These problems have been fixed in the stable distribution in version
2.6.18.dfsg.1-13etch5.
We recommend that you upgrade your kernel package immediately and reboot
the machine. If you have built a custom kernel from the kernel source
package, you will need to rebuild to take advantage of these fixes.
