Ubuntu Security Notice USN-1256-1

Posted Nov 9, 2011

Authored by Ubuntu | Site security.ubuntu.com

Ubuntu Security Notice 1256-1 - It was discovered that the /proc filesystem did not correctly handle permission changes when programs executed. A local attacker could hold open files to examine details about programs running with higher privileges, potentially increasing the chances of exploiting additional vulnerabilities. Vasiliy Kulikov discovered that the Bluetooth stack did not correctly clear memory. A local attacker could exploit this to read kernel stack memory, leading to a loss of privacy. Various other issues were also addressed.
