Description

This security bulletin contains information about 8 secuirty vulnerabilities.


1) Input validation error (CVE-ID: CVE-2022-21986)

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

The vulnerability exists due to insufficient validation of user-supplied input in ASP.NET Core Krestel when pooling HTTP/2 and HTTP/3 headers. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.


2) Insufficient verification of data authenticity (CVE-ID: CVE-2021-4122)

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

The vulnerability exists due to improper handling of the LUKS2 reencryption recover. A local attacker with physical access to the medium can send a specially crafted LUKS header and trick cryptsetup into disabling encryption during the recovery of the device.

3) Heap-based buffer overflow (CVE-ID: CVE-2021-3872)

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

The vulnerability exists due to a boundary error. A remote attacker can trick the victim to open a specially crafted file, trigger a heap-based buffer overflow and execute arbitrary code on the target system.

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


4) Heap-based buffer overflow (CVE-ID: CVE-2021-3984)

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

The vulnerability exists due to a boundary error. A remote attacker can trick the victim to open a specially crafted file, trigger a heap-based buffer overflow and execute arbitrary code on the target system.

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


5) Out-of-bounds write (CVE-ID: CVE-2021-4019)

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

The vulnerability exists due to a boundary error. A remote attacker can trick the victim to open a specially crafted file, trigger a heap-based buffer overflow and execute arbitrary code on the target system.

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


6) Use-after-free (CVE-ID: CVE-2021-4192)

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a use-after-free error. A remote attacker can trick the victim to open a specially crafted file, trigger a use-after-free error and execute arbitrary code on the system.

Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.


7) Out-of-bounds read (CVE-ID: CVE-2021-4193)

The vulnerability allows a remote attacker to crash the application.

The vulnerability exists due to a boundary condition. A remote attacker can create a specially crafted file, trick the victim into opening it, trigger out-of-bounds read error and crash the application.


8) Improper Verification of Cryptographic Signature (CVE-ID: CVE-2021-3521)

The vulnerability allows a remote attacker to compromise the affected system.

The vulnerability exists due to an error in RPM's signature functionality, as RPM does not check the binding signature of subkeys before importing them. A remote attacker with ability to add malicious subkey to a legitimate public key can run malicious code on the system.
