REDHAT-BUG-1542102: Integer Overflow
First published: Mon Feb 05 2018(Updated: )
A flaw was found in glibc. An integer overflow in the implementation of the posix_memalign in memalign functions in the GNU C Library (aka glibc or libc6) 2.26 and earlier could cause these functions to return a pointer to a heap area that is too small, potentially leading to heap corruption.
