• buffer overflow in the lldp_decode function in daemon/protocols/lldp.c (CVE-2015-8011)
• librte_vhost Integer overflow in vhost_user_set_log_base() (CVE-2020-10722)
• librte_vhost Integer truncation in vhost_user_check_and_alloc_queue_pair() (CVE-2020-10723)
• librte_vhost Missing inputs validation in Vhost-crypto (CVE-2020-10724) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page listed in the References section. Related CVEs:
