Descriptions

The BGP parser in tcpdump before 4.9.3 has a buffer over-read in print-bgp.c:bgp_capabilities_print() (BGP_CAPCODE_RESTART).

El analizador BGP en tcpdump versiones anteriores a 4.9.3, presenta una lectura excesiva del búfer en print-bgp.c:bgp_capabilities_print() (BGP_CAPCODE_RESTART).

An out-of-bounds read vulnerability was discovered in tcpdump while printing BGP packets captured in a pcap file or coming from the network. A remote attacker may abuse this flaw by sending specially crafted packets that, when printed, would trigger the flaw and crash the application.
