Security Bulletin

This security bulletin contains information about 3 vulnerabilities.

1) Buffer overflow

EUVDB-ID: #VU64137

Risk: Low

CVSSv4.0: 4.9 [CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2022-30552

CWE-ID: CWE-119 - Memory corruption

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a boundary error in the implementation of IP Packet Defragmentation. A remote attacker on the local network can trigger memory corruption and cause a denial of service condition on the target system.

Mitigation

Update the affected package u-boot to the latest version.

Vulnerable software versions

SUSE Linux Enterprise Server: 12-SP5

u-boot-tools-debuginfo: before 2019.01-5.8.1

u-boot-tools: before 2019.01-5.8.1

u-boot-rpi3: before 2019.01-5.8.1

Q & A

Can this vulnerability be exploited remotely?

Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the local network (LAN).

Is there known malware, which exploits this vulnerability?

No. We are not aware of malware exploiting this vulnerability.

2) Buffer overflow

EUVDB-ID: #VU64420

Risk: High

CVSSv4.0: 8.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber]

CVE-ID: CVE-2022-30767

CWE-ID: CWE-119 - Memory corruption

Exploit availability: No

Description

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error within the nfs_lookup_reply() function in net/nfs.c. A remote attacker can pass specially crafted data to the application, trigger memory corruption and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

Note, the vulnerability exists due to incomplete fix for CVE-2019-14196.

Mitigation

Update the affected package u-boot to the latest version.

CWE-ID: CWE-787 - Out-of-bounds write

Exploit availability: No

Description

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a boundary error when processing untrusted input in the implementation ofIP Packet Defragmentation. A remote attacker on the local netwotk can trigger out-of-bounds write and execute arbitrary code on the target system.

Mitigation

Update the affected package u-boot to the latest version.
