Description
This security bulletin contains information about 1 security vulnerability.
1) Out-of-bounds read (CVE-ID: CVE-2020-29130)
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.
