Subject: CVE Request: Three integer overflows in glibc memory allocator

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:

Thanks,
