Hi,

I recently discovered three integer overflow issues in the glibc 
memory allocator functions pvalloc, valloc and 
posix_memalign/memalign/aligned_alloc. These issues cause a large 
allocation size to wrap around and cause a wrong sized allocation
and heap corruption. The issues are fixed in glibc mainline.

The relevant glibc bugzilla entries are here:

https://sourceware.org/bugzilla/show_bug.cgi?id=15855 
https://sourceware.org/bugzilla/show_bug.cgi?id=15856 
https://sourceware.org/bugzilla/show_bug.cgi?id=15857

Thanks,

CVE MERGE, same researcher, version and vuln type.

Please use CVE-2013-4332  for this issue.
