Problem description

The kernel update fixes the following security problems:
  • CVE-2006-3626: A race condition allows local users to gain root privileges by changing the file mode of /proc/self/ files in a way that causes those files (for instance /proc/self/environ) to become setuid root. [#192688]
  • CVE-2006-2935: A stackbased buffer overflow in CDROM / DVD handling was fixed which could be used by a physical local attacker to crash the kernel or execute code within kernel context, depending on presence of automatic DVD handling in the system. [#190396]
  • CVE-2006-2451: Due to an argument validation error in prctl(PR_SET_DUMPABLE) a local attacker can easily gain administrator (root) privileges. [#186980]
and the following non security bugs:
  • Limit the maximum number of LUNs to 16384 [#185164]
  • LSI 1030/MPT Fusion driver hang during error recovery -- Optionally disable QAS [#180100]
  • advance buffer pointers in h_copy_rdma() to avoid data corruption [#186444]
