Security Bulletin
This security bulletin contains one medium risk vulnerability.
1) Out-of-bounds read
EUVDB-ID: #VU48696
Risk: Medium
CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2020-29130
CWE-ID:
CWE-125 - Out-of-bounds read
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to buffer over-read in slirp.c when processing ARP/NCSI packets in 'arp_input' or 'ncsi_input' routines, because the libslirp library tries to read a certain amount of header data even if that exceeds the total packet length. A remote attacker can perform a denial of service attack.
MitigationUpdate the affected package slirp4netns to the latest version.
