Security Bulletin

This security bulletin contains information about 6 vulnerabilities.

1) Heap-based buffer overflow

EUVDB-ID: #VU21446

Risk: Low

CVSSv4.0: 5.9 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2019-14814

CWE-ID: CWE-122 - Heap-based Buffer Overflow

Exploit availability: No

Description

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a boundary error within the mwifiex_update_vs_ie() function in the Marvell Wi-Fi chip driver in Linux kernel. A local user can run a specially crafted application to trigger a heap-based buffer overflow and execute arbitrary code on the system with elevated privileges.


Mitigation

Install updates from vendor's repository.

CVE-ID: CVE-2019-14816

CWE-ID: CWE-122 - Heap-based Buffer Overflow

Exploit availability: No

Description

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a boundary error within the mwifiex_set_wmm_params() function in the Marvell Wi-Fi chip driver in Linux kernel.

4) Double Free

EUVDB-ID: #VU20916

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-2019-15504

CWE-ID: CWE-415 - Double Free

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 in the "drivers/net/wireless/rsi/rsi_91x_usb.c". A remote attacker can trigger double free error via crafted USB device traffic (which may be remote via usbip or usbredir) and execute arbitrary code on the target system.

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

Mitigation

Install updates from vendor's repository.

Vulnerable software versions

Fedora: 30

kernel-tools: before 5.2.11-200.fc30

kernel-headers: before 5.2.11-200.fc30

5) Out-of-bounds read

EUVDB-ID: #VU21630

Risk: Low

CVSSv4.0: 0.4 [CVSS:4.0/AV:P/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2019-15505

CWE-ID: CWE-125 - Out-of-bounds read

Exploit availability: No

Description

The vulnerability allows a local user to gain access to potentially sensitive information.

The vulnerability exists due to a boundary condition within the drivers/media/usb/dvb-usb/technisat-usb2.c USB driver in Linux kernel. A local user can use a specially crafted USB device to trigger out-of-bounds read error during data transfer and read contents of memory on the system.

Mitigation

Install updates from vendor's repository.

No. The attacker should have physical access to the system in order to successfully exploit this vulnerability.

Is there known malware, which exploits this vulnerability?

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

6) Resource management error

EUVDB-ID: #VU20420

Risk: Medium

CVE-ID: CVE-2019-15538

CWE-ID: CWE-399 - Resource Management Errors

Exploit availability: No

Description

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

The vulnerability exists due to buggy implementation of quotas in "xfs_setattr_nonsize" in the "fs/xfs/xfs_iops.c" file. A local attacker can send specially crafted requests to the affected system and perform denial of service attack.

Note: This vulnerability can be exploited remotely, if XFS filesystem is exported for instance via NFS.

Mitigation

Install updates from vendor's repository.
