bgpd/bgp_flowspec.c in FRRouting (FRR) before 8.4.3 mishandles an nlri length of zero, aka a "flowspec overflow."
A flaw was found in bgpd/bgp_flowspec.c in the FFrouting BGP protocol code. An overflow may occur while processing zero length NLRI messages.
Отчет
Red Hat OpenStack Platform does not ship its own version of the frr package, instead using the version from the underlying Red Hat Enterprise Linux. RHOSP is marked as Not Affected as no changes need to be made by the OpenStack engineering team. System administrators of OpenStack deployments should apply updates once available in RHEL.
Меры по смягчению последствий
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
