Multiple integer signedness errors in the TIPC implementation in the Linux kernel before 2.6.36.2 allow local users to gain privileges via a crafted sendmsg call that triggers a heap-based buffer overflow, related to the tipc_msg_build function in net/tipc/msg.c and the verify_iovec function in net/core/iovec.c. kernel: tipc: heap overflow in tipc_msg_build() Red Hat is aware of this issue and is tracking it via the following bug: https://bugzilla.redhat.com/CVE-2010-3859. This issue did not affect the version of Linux kernel as shipped with Red Hat Enterprise Linux 3, 4, 6 and Red Hat Enterprise MRG as they did not include support for Transparent Inter-Process Communication Protocol (TIPC). A future kernel update in Red Hat Enterprise Linux 5 may address this flaw. As a preventive measure, we plan to include the fixes in a future kernel update in Red Hat Enterprise Linux 4.
