SUSE update for slirp4netns

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

Description

The 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.

Mitigation

Update the affected package slirp4netns to the latest version.
