Ubuntu Security Notice 1204-1 - Dan Rosenberg discovered that the Linux kernel TIPC implementation contained multiple integer signedness errors. A local attacker could exploit this to gain root privileges. 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. Various other issues were also addressed.
