Ubuntu 9.10 : linux, linux-ec2 vulnerabilities (USN-1089-1)

Ubuntu Security Notice (C) 2011-2014 Canonical, Inc. / NASL script (C) 2011-2014 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing one or more security-related patches.

Description :

Dan Rosenberg discovered that multiple terminal ioctls did not
correctly initialize structure memory. A local attacker could exploit
this to read portions of kernel stack memory, leading to a loss of
privacy. (CVE-2010-4075, CVE-2010-4076, CVE-2010-4077)

Dan Rosenberg discovered that the socket filters did not correctly
initialize structure memory. A local attacker could create malicious
filters to read portions of kernel stack memory, leading to a loss of
privacy. (CVE-2010-4158)

Dan Rosenberg discovered that certain iovec operations did not
calculate page counts correctly. A local attacker could exploit this
to crash the system, leading to a denial of service. (CVE-2010-4162)

Dan Rosenberg discovered that the SCSI subsystem did not correctly
validate iov segments. A local attacker with access to a SCSI device
could send specially crafted requests to crash the system, leading to
a denial of service. (CVE-2010-4163)

Dan Rosenberg discovered that the RDS protocol did not correctly check
ioctl arguments. A local attacker could exploit this to crash the
system, leading to a denial of service. (CVE-2010-4175)

Alan Cox discovered that the HCI UART driver did not correctly check
if a write operation was available. If the mmap_min-addr sysctl was
changed from the Ubuntu default to a value of 0, a local attacker
could exploit this flaw to gain root privileges. (CVE-2010-4242).

Solution :

Update the affected packages.

Risk factor :

Medium / CVSS Base Score : 4.9
(CVSS2#AV:L/AC:L/Au:N/C:N/I:N/A:C)
CVSS Temporal Score : 4.3
(CVSS2#E:ND/RL:OF/RC:ND)
Public Exploit Available : false
