This security bulletin contains information about 3 vulnerabilities.
EUVDB-ID: #VU54308
Risk: Low
CVSSv3.1: 3.8 [CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:C/C:L/I:N/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2021-3592
CWE-ID:
CWE-763 - Release of invalid pointer or reference
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to invalid pointer initialization within the bootp_input() function while processing UDP packets in the SLiRP networking implementation of QEMU. A malicious guest could use this flaw to leak 10 bytes of uninitialized heap memory from the host.
MitigationUpdate the affected package libslirp to the latest version.
