| Descripción: | Summary:
The remote host is missing an update for the 'kernel'
package(s) announced via the referenced advisory.
Vulnerability Insight:
The kernel packages contain the Linux kernel, the core of any Linux
operating system.
These updated packages fix the following security issues:
* a flaw was found in the IPv4 forwarding base. This could allow a local,
unprivileged user to cause a denial of service. (CVE-2007-2172,
Important)
* a flaw was found in the handling of process death signals. This allowed a
local, unprivileged user to send arbitrary signals to the suid-process
executed by that user. Successful exploitation of this flaw depends on the
structure of the suid-program and its signal handling. (CVE-2007-3848,
Important)
* when accessing kernel memory locations, certain Linux kernel drivers
registering a fault handler did not perform required range checks. A local,
unprivileged user could use this flaw to gain read or write access to
arbitrary kernel memory, or possibly cause a denial of service.
(CVE-2008-0007, Important)
* a possible kernel memory leak was found in the Linux kernel Simple
Internet Transition (SIT) INET6 implementation. This could allow a local,
unprivileged user to cause a denial of service. (CVE-2008-2136, Important)
* missing capability checks were found in the SBNI WAN driver which could
allow a local, unprivileged user to bypass intended capability
restrictions. (CVE-2008-3525, Important)
* a flaw was found in the way files were written using truncate() or
ftruncate(). This could allow a local, unprivileged user to acquire the
privileges of a different group and obtain access to sensitive information.
(CVE-2008-4210, Important)
* a race condition in the mincore system core allowed a local, unprivileged
user to cause a denial of service. (CVE-2006-4814, Moderate)
* a flaw was found in the aacraid SCSI driver. This allowed a local,
unprivileged user to make ioctl calls to the driver which should otherwise
be restricted to privileged users. (CVE-2007-4308, Moderate)
* two buffer overflow flaws were found in the Integrated Services Digital
Network (ISDN) subsystem. A local, unprivileged user could use these flaws
to cause a denial of service. (CVE-2007-6063, CVE-2007-6151, Moderate)
* a flaw was found in the way core dump files were created. If a local,
unprivileged user could make a root-owned process dump a core file into a
user-writable directory, the user could gain read access to that core file,
potentially compromising sensitive information. (CVE-2007-6206, Moderate)
* a deficiency was found in the Linux kernel virtual file system (VFS)
implementation. This could allow a local, unprivileged ...
