| Description: | Summary:
The remote host is missing an update for the 'linux, linux-source-2.6.15' package(s) announced via the USN-864-1 advisory.
Vulnerability Insight:
It was discovered that the AX.25 network subsystem did not correctly
check integer signedness in certain setsockopt calls. A local attacker
could exploit this to crash the system, leading to a denial of service.
Ubuntu 9.10 was not affected. (CVE-2009-2909)
Jan Beulich discovered that the kernel could leak register contents to
32-bit processes that were switched to 64-bit mode. A local attacker
could run a specially crafted binary to read register values from an
earlier process, leading to a loss of privacy. (CVE-2009-2910)
Dave Jones discovered that the gdth SCSI driver did not correctly validate
array indexes in certain ioctl calls. A local attacker could exploit
this to crash the system or gain elevated privileges. (CVE-2009-3080)
Eric Dumazet and Jiri Pirko discovered that the TC and CLS subsystems
would leak kernel memory via uninitialized structure members. A local
attacker could exploit this to read several bytes of kernel memory,
leading to a loss of privacy. (CVE-2009-3228, CVE-2009-3612)
Earl Chew discovered race conditions in pipe handling. A local attacker
could exploit anonymous pipes via /proc/*/fd/ and crash the system or
gain root privileges. (CVE-2009-3547)
Dave Jones and Francois Romieu discovered that the r8169 network driver
could be made to leak kernel memory. A remote attacker could send a large
number of jumbo frames until the system memory was exhausted, leading
to a denial of service. Ubuntu 9.10 was not affected. (CVE-2009-3613).
Ben Hutchings discovered that the ATI Rage 128 video driver did not
correctly validate initialization states. A local attacker could
make specially crafted ioctl calls to crash the system or gain root
privileges. (CVE-2009-3620)
Tomoki Sekiyama discovered that Unix sockets did not correctly verify
namespaces. A local attacker could exploit this to cause a system hang,
leading to a denial of service. (CVE-2009-3621)
J. Bruce Fields discovered that NFSv4 did not correctly use the credential
cache. A local attacker using a mount with AUTH_NULL authentication
could exploit this to crash the system or gain root privileges. Only
Ubuntu 9.10 was affected. (CVE-2009-3623)
Alexander Zangerl discovered that the kernel keyring did not correctly
reference count. A local attacker could issue a series of specially
crafted keyring calls to crash the system or gain root privileges.
Only Ubuntu 9.10 was affected. (CVE-2009-3624)
David Wagner discovered that KVM did not correctly bounds-check CPUID
entries. A local attacker could exploit this to crash the system
or possibly gain elevated privileges. Ubuntu 6.06 and 9.10 were not
affected. (CVE-2009-3638)
Avi Kivity discovered that KVM did not correctly check privileges when
accessing debug registers. A local attacker could exploit this to
crash a host system from within a guest system, leading to a denial of
service. Ubuntu 6.06 and 9.10 were not affected. ... [Please see the references for more information on the vulnerabilities]
