Description
This security bulletin contains information about 14 secuirty vulnerabilities.
1) Out-of-bounds write (CVE-ID: CVE-2020-0465)
The vulnerability allows an attacker with physical access to escalate privileges on the system.
The vulnerability exists due to an out of bounds write in various methods of hid-multitouch.c. An attacker with physical access can trigger out-of-bounds write and escalate privileges on the system.
2) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2020-0466)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to unspecified error, related to I/O subsystem in kernel. A local user can elevated privileges on the system.
3) Use-after-free (CVE-ID: CVE-2021-0920)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a use-after-free error within the unix_scm_to_skb() function of af_unix.c in Linux kernel. A local user can run a specially crafted program to trigger a race condition and execute arbitrary code with elevated privileges.
4) NULL pointer dereference (CVE-ID: CVE-2021-26691)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error in mod_session. A a malicious backend server or SessionHeader can trigger a denial of service (DoS) condition.
5) NULL pointer dereference (CVE-ID: CVE-2021-34798)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error. A remote attacker can send a specially crafted HTTP request to the affected web server and perform a denial of service (DoS) attack.
6) Double Free (CVE-ID: CVE-2021-3564)
The vulnerability allows a local attacker to perform a denial of service attack.
The vulnerability exists due to bluetooth subsystem in the Linux kernel does not properly handle HCI device detach events. An attacker with physical access to the system can trigger double free error and perform a denial of service attack.
7) Use-after-free (CVE-ID: CVE-2021-3573)
The vulnerability allows local user to escalate their privileges on the system.
The vulnerability exists due to a use-after-free in hci_sock_bound_ioctl() function of the Linux kernel HCI subsystem triggers race condition of the call hci_unregister_dev() together with one of the calls hci_sock_blacklist_add(), hci_sock_blacklist_del(), hci_get_conn_info(), hci_get_auth_info(). A privileged local user can use this flaw to crash the system or escalate privileges on the system.
8) Command Injection (CVE-ID: CVE-2021-3621)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to improper input validation in the sssctl command within the logs-fetch and cache-expire subcommands. An attacker can trick the root user into running a specially crafted sssctl command, such as via sudo, and execute arbitrary code with root privileges.
9) Use-after-free (CVE-ID: CVE-2021-3752)
The vulnerability allows a remote attacker to escalate privileges on the system.
The vulnerability exists due to a use-after-free error in the Linux kernel’s Bluetooth subsystem when a user calls connect to the socket and disconnect simultaneously. A local user can escalate privileges on the system.
10) Buffer overflow (CVE-ID: CVE-2021-39275)
The vulnerability allows a remote attacker to execute arbitrary code on the target system or perform a denial of service attack.
The vulnerability exists due to a boundary error within the ap_escape_quotes() function. A remote attacker can send a specially crafted request to the web server, trigger memory corruption and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system but requires that the Apache module passes untrusted data to the affected function.
According to vendor, No included modules pass untrusted data to these functions
11) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2021-4155)
The vulnerability allows a local user to bypass implemented security restrictions.
The vulnerability exists due to the OS kernel does not impose correctly security restrictions. A local user can gain access to sensitive information on the system.
12) Buffer overflow (CVE-ID: CVE-2021-44790)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when parsing multipart content in mod_lua. A remote attacker can send a specially crafted HTTP request to the affected web server, trigger buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
13) Buffer overflow (CVE-ID: CVE-2022-0330)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a random memory access flaw caused by a missing TLB flush in Linux kernel GPU i915 kernel driver functionality. A local user can execute arbitrary code on the system with elevated privileges.
14) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2022-22942)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to an error in the vmwgfx driver in Linux kernel. A local unprivileged user can gain access to files opened by other processes on the system through a dangling 'file' pointer.
Exploiting this vulnerability requires an attacker to have access to either /dev/dri/card0 or /dev/dri/rendererD128 and be able to issue an ioctl() on the resulting file descriptor.
