Security Bulletin
This security bulletin contains information about 5 vulnerabilities.
1) Out-of-bounds write
EUVDB-ID: #VU24684
Risk: Medium
CVSSv4.0: 6.3 [CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]
CVE-ID: CVE-2019-14901
CWE-ID:
CWE-787 - Out-of-bounds write
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error when processing untrusted input in Marvell WiFi chip driver within the "mwifiex_process_tdls_action_frame()" function in "marvell/mwifiex/tdls.c". A remote attacker on the local network can send a specially crafted network traffic, trigger out-of-bounds write and execute arbitrary code on the target system.
MitigationInstall updates from vendor's repository.
Vulnerable software versionsFedora: 31
kernel: before 5.3.13-300.fc31
CPE2.3 External linkshttps://bodhi.fedoraproject.org/updates/FEDORA-2019-91f6e7bb71
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) Out-of-bounds write
EUVDB-ID: #VU28406
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-2019-14895
CWE-ID:
CWE-787 - Out-of-bounds write
Exploit availability: No
DescriptionThe vulnerability allows a remote non-authenticated attacker to execute arbitrary code.
A heap-based buffer overflow was discovered in the Linux kernel, all versions 3.x.x and 4.x.x before 4.18.0, in Marvell WiFi chip driver. The flaw could occur when the station attempts a connection negotiation during the handling of the remote devices country settings. This could allow the remote device to cause a denial of service (system crash) or possibly execute arbitrary code.

No. We are not aware of malware exploiting this vulnerability.
3) Out-of-bounds write
EUVDB-ID: #VU28409
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-2019-14896
CWE-ID:
CWE-787 - Out-of-bounds write
Exploit availability: No
DescriptionThe vulnerability allows a remote non-authenticated attacker to execute arbitrary code.
A heap-based buffer overflow vulnerability was found in the Linux kernel, version kernel-2.6.32, in Marvell WiFi chip driver. A remote attacker could cause a denial of service (system crash) or, possibly execute arbitrary code, when the lbs_ibss_join_existing function is called after a STA connects to an AP.

4) Out-of-bounds write
EUVDB-ID: #VU28408
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-2019-14897
CWE-ID:
CWE-787 - Out-of-bounds write
Exploit availability: No
DescriptionThe vulnerability allows a remote non-authenticated attacker to execute arbitrary code.
A stack-based buffer overflow was found in the Linux kernel, version kernel-2.6.32, in Marvell WiFi chip driver. An attacker is able to cause a denial of service (system crash) or, possibly execute arbitrary code, when a STA works in IBSS mode (allows connecting stations together without the use of an AP) and connects to another STA.

5) Memory leak
EUVDB-ID: #VU23035
Risk: Medium
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:Green]
CVE-ID: CVE-2019-19078
CWE-ID:
CWE-401 - Missing release of memory after effective lifetime
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to memory leak within the "ath10k_usb_hif_tx_sg()" function in "drivers/net/wireless/ath/ath10k/usb.c" file. A remote attacker can cause a denial of service condition (memory consumption) by triggering "usb_submit_urb()" failures.
