Description Stefan Behte (RETIRED) gentoo-dev Security 2009-02-11 12:50:43 UTC 
CVE-2008-6107 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2008-6107):
  The (1) sys32_mremap function in arch/sparc64/kernel/sys_sparc32.c,
  the (2) sparc_mmap_check function in arch/sparc/kernel/sys_sparc.c,
  and the (3) sparc64_mmap_check function in
  arch/sparc64/kernel/sys_sparc.c, in the Linux kernel before 2.6.25.4,
  omit some virtual-address range (aka span) checks when the mremap
  MREMAP_FIXED bit is not set, which allows local users to cause a
  denial of service (panic) via unspecified mremap calls, a related
  issue to CVE-2008-2137.
