Description
This security bulletin contains information about 15 secuirty vulnerabilities.
1) Input validation error (CVE-ID: CVE-2020-26147)
The vulnerability allows a remote attacker to compromise the target system.
The vulnerability exists due to the WEP, WPA, WPA2, and WPA3 implementations reassemble fragments even though some of them were sent in plaintext. A remote attacker on the local network can inject packets and/or exfiltrate selected fragments
2) Input validation error (CVE-ID: CVE-2020-26140)
The vulnerability allows a remote attacker to compromise the target system.
The vulnerability exists due to the WEP, WPA, WPA2, and WPA3 implementations accept plaintext frames in a protected Wi-Fi network. A remote attacker on the local network can inject arbitrary data frames independent of the network configuration.
3) Out-of-bounds write (CVE-ID: CVE-2020-29368)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a boundary error when processing untrusted input within the __split_huge_pmd() function in mm/huge_memory.c in the Linux kernel. A local user can abuse the copy-on-write implementation and gain unintended write access because of a race condition in a THP mapcount check.
4) Spoofing attack (CVE-ID: CVE-2020-24588)
The vulnerability allows a remote attacker to perform spoofing attack.
The vulnerability exists due to incorrect processing of user-supplied data in Windows Wireless Networking. A remote attacker on the local network can spoof page content.
5) Improper locking (CVE-ID: CVE-2020-29660)
The vulnerability allows a local user to gain access to sensitive information.
The vulnerability exists due to double-locking error in drivers/tty/tty_io.c and drivers/tty/tty_jobctrl.c. An authenticated local user can exploit this vulnerability to perform a read-after-free attack against TIOCGSID and gain access to sensitive information.
6) Input validation error (CVE-ID: CVE-2020-10768)
The vulnerability allows a local authenticated user to gain access to sensitive information.
A flaw was found in the Linux Kernel before 5.8-rc1 in the prctl() function, where it can be used to enable indirect branch speculation after it has been disabled. This call incorrectly reports it as being 'force disabled' when it is not and opens the system to Spectre v2 attacks. The highest threat from this vulnerability is to confidentiality.
7) Information disclosure (CVE-ID: CVE-2021-29647)
The vulnerability allows a local user to gain access to potentially sensitive information.
The vulnerability exists due to an error in qrtr_recvmsg(0 function in net/qrtr/qrtr.c caused by a partially uninitialized data structure. A local user can read sensitive information from kernel memory.
8) Improper Authentication (CVE-ID: CVE-2020-11264)
The vulnerability allows a remote attacker to bypass authentication process.
The vulnerability exists due to an error in WLAN Windows Host when processing Non-EAPOL/WAPI plaintext frames during four-way handshake. A remote attacker can bypass authentication process and inject arbitrary network packets, leading to full compromise of the affected device.
9) Improper Authentication (CVE-ID: CVE-2020-11301)
The vulnerability allows a remote attacker to bypass authentication process.
The vulnerability exists due to an error in WIGIG when processing un-encrypted plaintext Wi-Fi frames in an encrypted network. A remote attacker can bypass authentication process and gain access to sensitive information.
10) Information disclosure (CVE-ID: CVE-2020-24587)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to excessive data output by the application in Windows Wireless Networking. A remote attacker on the local network can gain unauthorized access to sensitive information on the system.
11) Input validation error (CVE-ID: CVE-2020-26139)
The vulnerability allows a remote attacker to compromise the target system.
The vulnerability exists due to forwarding EAPOL frames even though the sender is not yet authenticated. A remote attacker on the local network can cause a denial of service (DoS) condition on the target system.
12) Input validation error (CVE-ID: CVE-2020-26141)
The vulnerability allows a remote attacker to compromise the target system.
The vulnerability exists due to the Wi-Fi implementation does not verify the Message Integrity Check (authenticity) of fragmented TKIP frames. A remote attacker on the local network can inject and possibly decrypt packets in WPA or WPA2 networks that support the TKIP data-confidentiality protocol.
13) Input validation error (CVE-ID: CVE-2020-26145)
The vulnerability allows a remote attacker to compromise the target system.
The vulnerability exists due to the WEP, WPA, WPA2, and WPA3 implementations accept second (or subsequent) broadcast fragments even when sent in plaintext and process them as full unfragmented frames. A remote attacker on the local network can inject arbitrary network packets independent of the network configuration.
14) Input validation error (CVE-ID: CVE-2020-26146)
The vulnerability allows a remote attacker to compromise the target system.
The vulnerability exists due to the WPA, WPA2, and WPA3 implementations reassemble fragments with non-consecutive packet numbers. A remote attacker on the local network can exfiltrate selected fragments.
15) Out-of-bounds write (CVE-ID: CVE-2020-15358)
The vulnerability allows a local authenticated user to perform a denial of service (DoS) attack.
In SQLite before 3.32.3, select.c mishandles query-flattener optimization, leading to a multiSelectOrderBy heap overflow because of misuse of transitive properties for constant propagation.
