USN-1089-1: Linux kernel vulnerabilities
First published: Fri Mar 18 2011(Updated: )
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)
