Publication date
25 March 2011
Overview
A local attacker could exploit this to run programs with admininstrator privileges.
Releases
Packages
- linux-source-2.6.15 - ACPI support modules (udeb)
Details
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-2010-4077)
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)
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)
Update instructions
The problem can be corrected by updating your system to the following package versions:
Reduce your security exposure
Ubuntu Pro provides ten-year security coverage to 25,000+ packages in Main and Universe repositories, and it is free for up to five machines.
