Description

The remote Debian 11 host has packages installed that are affected by a vulnerability as referenced in the dsa-5362 advisory.

An out-of-bounds read in the BGP daemon of FRRouting FRR before 8.4 may lead to a segmentation fault and denial of service. This occurs in bgp_capability_msg_parse in bgpd/bgp_packet.c.
