CVE-2010-1451 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2010-1451):
  The TSB I-TLB load implementation in arch/sparc/kernel/tsb.S in the
  Linux kernel before 2.6.33 on the SPARC platform does not properly
  obtain the value of a certain _PAGE_EXEC_4U bit and consequently does
  not properly implement a non-executable stack, which makes it easier
  for context-dependent attackers to exploit stack-based buffer
  overflows via a crafted application.
