Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) Buffer overflow
EUVDB-ID: #VU48780
Risk: High
CVSSv3.1: 8.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2015-8011
CWE-ID:
CWE-119 - Memory corruption
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within the lldp_decode() function in daemon/protocols/lldp.c in lldpd. A remote attacker can pass specially crafted data to the application, trigger memory corruption and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
