CVE-2007-6754 - Unsalted Friction

Description

The ipalloc function in libc/stdlib/malloc.c in jemalloc in libc for FreeBSD 6.4 and NetBSD does not properly allocate memory which makes it easier for context-dependent attackers to perform memory-related attacks such as buffer overflows via a large size value related to \integer rounding and overflow\ errors.
