EUVDB-ID: #VU15555
Risk: High
CVSSv3.1: 8.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2018-15688
CWE-ID:
CWE-787 - Out-of-bounds write
Exploit availability: No
Description
The vulnerability allows a remote attacker to cause DoS condition or execute arbitrary code with elevated privileges.
The weakness exists within the written-from-scratch DHCPv6 client of the open-source Systemd management suite due to an out-of-bounds heap write in the DHCPv6 client when handling options sent by network adjacent DHCP servers. A remote attacker can supply maliciously crafted DHCPv6 packets, exploit the programming cockup, arbitrarily change parts of memory to crash or execute arbitrary code on the vulnerable Systemd-powered Linux machines.
MitigationUpdate the affected packages.
