Ubuntu Security Notice USN-1211-1

Posted Sep 21, 2011

Authored by Ubuntu | Site security.ubuntu.com

Ubuntu Security Notice 1211-1 - 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. Dan Rosenberg discovered that the X.25 Rose network stack did not correctly handle certain fields. If a system was running with Rose enabled, a remote attacker could send specially crafted traffic to gain root privileges. Various other issues were also addressed.
