Integer overflow in the calloc function in libc/stdlib/malloc.c in jemalloc in libc for FreeBSD 6.4 and NetBSD makes it easier for context-dependent attackers to perform memory-related attacks such as buffer overflows via a large size value, which triggers a memory allocation of one byte.

Security readout for executives and security teams

This is an old memory-allocation flaw in libc jemalloc calloc. On affected FreeBSD 6.4 and NetBSD systems, an extremely large allocation size could wrap around and allocate too little memory, increasing the chance of memory corruption in vulnerable programs. Exposure is most likely on legacy FreeBSD 6.4 or NetBSD systems using the affected libc jemalloc calloc implementation, especially services processing attacker-controlled allocation sizes. The source bundle does not provide exact NetBSD version ranges or CPEs. Treat this as a legacy-platform risk. It is not supported by evidence of active exploitation here, but affected systems should be retired or verified because allocator flaws can undercut many applications at once. Mitigation focus: Inventory legacy FreeBSD 6.4 and NetBSD hosts.; Upgrade unsupported operating systems where possible.; Verify libc includes the vendor allocator fix..
