Description

This security bulletin contains information about 8 secuirty vulnerabilities.


1) Improper Certificate Validation (CVE-ID: CVE-2022-4492)

The vulnerability allows a remote attacker to perform MitM attack.

The vulnerability exists due to the undertow client does not check the server identity presented by the server certificate in https connections. A remote attacker can perform MitM attack.


2) Use-after-free (CVE-ID: CVE-2021-3782)

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

The vulnerability exists due to a use-after-free error caused by incorrectly handled reference counting
certain objects. A local user can perform a denial of service (DoS) attack against the Wayland compositor or execute arbitrary code with elevated privileges.


3) Out-of-bounds write (CVE-ID: CVE-2022-3627)

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a boundary error when processing TIFF images within the _TIFFmemcpy() function in libtiff/tif_unix.c. A remote attacker can pass a specially crafted TIFF file to the application, trigger an out-of-bounds write and execute arbitrary code on the target system.


4) Integer overflow (CVE-ID: CVE-2022-3970)

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

The vulnerability exists due to integer overflow within the TIFFReadRGBATileExt() function in libtiff/tif_getimage.c. A remote attacker can trick the victim to open a specially crafted TIFF file, trigger an integer overflow and execute arbitrary code on the target system.

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


5) NULL pointer dereference (CVE-ID: CVE-2022-36227)

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 libarchive. A remote attacker can pass a specially crafted archive to the application and perform a denial of service (DoS) attack.


6) Inadequate Encryption Strength (CVE-ID: CVE-2023-0361)

The vulnerability allows a remote attacker to perform MitM attack.

The vulnerability exists due to an error in the TLS RSA key exchange. A remote attacker can perform Bleichenbacher oracle attack and decrypt information.


7) OS Command Injection (CVE-ID: CVE-2023-2491)

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

The vulnerability exists due to a missing fix for #VU74578 (CVE-2023-28617). A remote attacker can trick the victim to open a specially crafted file and execute arbitrary OS commands on the target system via a file name or directory name that contains shell metacharacters.


8) State Issues (CVE-ID: CVE-2023-27535)

The vulnerability allows a remote attacker to gain unauthorized access to FTP server.

The vulnerability exists due to cURL will reuse a previously created FTP connection even when one or more options had been changed that could have made the effective user a very different one. A remote attacker can connect to the FTP server using credentials supplied by another user and gain access to otherwise restricted functionality.

The settings in questions are CURLOPT_FTP_ACCOUNT, CURLOPT_FTP_ALTERNATIVE_TO_USER, CURLOPT_FTP_SSL_CCC and CURLOPT_USE_SSL level.
