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

medium Nessus Plugin ID 52739

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).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution
