            Bug ID: 18016
           Summary: Signed size comparison in memcpy-ssse3.S
                    (CVE-2011-2702)
           Product: glibc
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: libc
          Assignee: unassigned at sourceware dot org
          Reporter: fweimer at redhat dot com
                CC: drepper.fsp at gmail dot com
             Flags: security+

CVE mapping is based on an archived copy of
http://www.nodefense.org/eglibc.txt.

The signed comparison in __memcpy_ssse3 means that an out-of-bounds reference
is used for the jump table, which allows code execution and ASLR bypass (due to
the relative addressing).
