Описание
An issue was discovered in lldpd before 1.0.17. By crafting a CDP PDU packet with specific CDP_TLV_ADDRESSES TLVs, a malicious actor can remotely force the lldpd daemon to perform an out-of-bounds read on heap memory. This occurs in cdp_decode in daemon/protocols/cdp.c.
A flaw was found in lldpd due to an out-of-bounds read in cdp_decode at daemon/protocols/cdp.c. By sending a specially crafted CDP PDU packet with specific CDP_TLV_ADDRESSES TLVs, a remote attacker could cause a denial of service.
Отчет
The highest threat from this vulnerability is system availability.
