5.5.18 is already in Fedora testing, so no Fedora trackers for this (or bug 1154502 and bug 1154503) (In reply to Murray McAllister from comment #0) > It was reported that this issue only affects 32-bit systems. This issue does not seem to be 32-bit specific per se. Problematic code check is: pointer1 + long >= pointer2 Attacker providing crafted serialized input has full control over the long value. As the variable is signed, and there is another check to ensure that its value is not negative, overflow can happen if pointer1 + long overflow. That can only happen if pointer1 points to the upper half of the address range, as the maximum long value is approximately half of the maximum pointer value. That is lot more likely on 32-bit systems than on 64-bit systems. Attacker has limited control over pointer1.
