| Description: | Description:
The remote host is missing an update to linux-source-2.6.17
announced via advisory USN-509-1.
A security issue affects the following Ubuntu releases:
Ubuntu 6.10
This advisory also applies to the corresponding versions of
Kubuntu, Edubuntu, and Xubuntu.
Details follow:
A flaw in the sysfs_readdir function allowed a local user to cause a
denial of service by dereferencing a NULL pointer. (CVE-2007-3104)
A buffer overflow was discovered in the random number generator. In
environments with granular assignment of root privileges, a local attacker
could gain additional privileges. (CVE-2007-3105)
A flaw was discovered in the usblcd driver. A local attacker could cause
large amounts of kernel memory consumption, leading to a denial of service.
(CVE-2007-3513)
It was discovered that certain setuid-root processes did not correctly
reset process death signal handlers. A local user could manipulate this
to send signals to processes they would not normally have access to.
(CVE-2007-3848)
The Direct Rendering Manager for the i915 driver could be made to write
to arbitrary memory locations. An attacker with access to a running X11
session could send a specially crafted buffer and gain root privileges.
(CVE-2007-3851)
It was discovered that the aacraid SCSI driver did not correctly check
permissions on certain ioctls. A local attacker could cause a denial
of service or gain privileges. (CVE-2007-4308)
