Security Bulletin

This security bulletin contains information about 3 vulnerabilities.

1) Release of invalid pointer or reference

EUVDB-ID: #VU54308

Risk: Low

CVSSv4.0: 1.2 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2021-3592

CWE-ID: CWE-763 - Release of invalid pointer or reference

Exploit availability: No

Description

The 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.

Mitigation

Update the affected package libslirp to the latest version.

2) Release of invalid pointer or reference

EUVDB-ID: #VU54310

Risk: Low

CVSSv4.0: 1.2 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2021-3594

CWE-ID: CWE-763 - Release of invalid pointer or reference

Exploit availability: No

Description

The vulnerability allows a remote attacker to gain access to sensitive information.

The vulnerability exists due to invalid pointer initialization within the udp_input() function while processing UDP packets in the SLiRP networking implementation of QEMU. A malicious guest could use this vulnerability to read host memory.

Mitigation

Update the affected package libslirp to the latest version.
