Description

This security bulletin contains information about 20 secuirty vulnerabilities.


1) Integer overflow (CVE-ID: CVE-2022-23521)

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

The vulnerability exists due to insufficient validation of user-supplied input when parsing the .gitattributes attributes. A remote attacker can trick the victim into cloning a specially crafted repository and execute arbitrary code on the system.


2) Heap-based buffer overflow (CVE-ID: CVE-2022-0417)

The vulnerability allows a remote attacker to crash the application.

The vulnerability exists due to a boundary error. A remote attacker can trick the victim to open a specially crafted file and crash the application.


3) Heap-based buffer overflow (CVE-ID: CVE-2022-0392)

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) Untrusted search path (CVE-ID: CVE-2022-4883)

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

The vulnerability exists due to libXpm relies on the $PATH variable to run the command responsible for decompressing .Z or .gz files. A local user can execute arbitrary code with elevated privileges.


5) Infinite loop (CVE-ID: CVE-2022-46285)

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

The vulnerability exists due to infinite loop when handling unclosed comments in XPM images within the ParseComment() function. A remote attacker can trick the victim to open a specially crafted image and cause denial of service conditions.


6) Infinite loop (CVE-ID: CVE-2022-44617)

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

The vulnerability exists due to infinite loop within the ParsePixels() function when handling XPM files with width set to 0 and a very large height value. A remote attacker can trick the victim to open a specially crafted XPM file and perform a denial of service (DoS) attack.


7) Input validation error (CVE-ID: CVE-2022-33070)

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 within the parse_tag_and_wiretype() function in protobuf-c/protobuf-c.c. A remote attacker can trick the victim to open a specially crafted file, cause an invalid arithmetic shift and perform a denial of service (DoS) attack.


8) Input validation error (CVE-ID: CVE-2023-22809)

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

The vulnerability exists within the sudoedit (aka -e) feature due to insufficient validation of user-supplied input passed in the user-provided environment variables (SUDO_EDITOR, VISUAL, and EDITOR). The problem exists because a user-specified editor may contain a "--" argument that defeats a protection mechanism, e.g., an EDITOR='vim -- /path/to/extra/file' value. A local user can append arbitrary entries to the list of files to process and escalate privileges on the system.


9) Heap-based buffer overflow (CVE-ID: CVE-2022-41903)

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

The vulnerability exists due to a boundary error during git archive invocation. A remote attacker can trick the victim into using the application against a specially crafted archive, 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.


10) HTTP response splitting (CVE-ID: CVE-2021-33621)

The vulnerability allows a remote attacker to perform HTTP splitting attacks.

The vulnerability exists due to software does not corrector process CRLF character sequences when handling cookies. A remote attacker can send specially crafted request containing CRLF sequence and make the application to send a split HTTP response.

Successful exploitation of the vulnerability may allow an attacker perform cache poisoning attack.


11) Error Handling (CVE-ID: CVE-2022-45142)

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

The vulnerability exists due to a logic issue in Heimdal GSSAPI related to patch for vulnerability #VU68701 (CVE-2022-3437). A remote user can perform a denial of service (DoS) attack.


12) Incorrect authorization (CVE-ID: CVE-2022-28321)

The vulnerability allows a remote attacker to bypass authorization process.

The vulnerability exists due to an error within the pam_access.so module in Linux-PAM package, which does not correctly restrict login if a user tries to connect from an IP address that is not resolvable via DNS.  A remote attacker can bypass authorization process and login to the system via SSH from IP addresses that were not allowed to connect from.


13) NULL pointer dereference (CVE-ID: CVE-2023-0401)

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

The vulnerability exists due to a NULL pointer dereference error during PKCS7 data verification. A remote attacker can pass specially crafted data to the application and perform a denial of service (DoS) attack.


14) NULL pointer dereference (CVE-ID: CVE-2023-0217)

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

The vulnerability exists due to a NULL pointer dereference error when validating the DSA public key. A remote attacker can pass specially crafted data to the application and perform a denial of service (DoS) attack.


15) Release of invalid pointer or reference (CVE-ID: CVE-2023-0216)

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

The vulnerability exists due to invalid pointer dereference in d2i_PKCS7 functions. A remote attacker can perform a denial of service (DoS) attack.


16) Double Free (CVE-ID: CVE-2022-4450)

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

The vulnerability exists due to a boundary error within the PEM_read_bio_ex() function. A remote attacker can pass specially crafted PEM file to the application, trigger a double free error and perform a denial of service (DoS) attack.


17) Information Exposure Through Timing Discrepancy (CVE-ID: CVE-2022-4304)

The vulnerability allows a remote attacker to obtain sensitive information.

The vulnerability exists due to a timing based side channel exists in the OpenSSL RSA Decryption implementation. A remote attacker can perform a Bleichenbacher style attack and decrypt data sent over the network.

To achieve a successful decryption an attacker would have to be able to send a very large number of trial messages for decryption. The vulnerability affects all RSA padding modes: PKCS#1 v1.5, RSA-OEAP and RSASVE.


18) Out-of-bounds read (CVE-ID: CVE-2022-4203)

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to a boundary condition when performing name constraint checking of the X.509 certificates. A remote attacker can pass a specially crafted X.509 certificate to the affected server, trigger an out-of-bounds read error and read contents of memory on the system.


19) Use-after-free (CVE-ID: CVE-2023-0215)

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

The vulnerability exists due to a use-after-free error within the BIO_new_NDEF function. A remote attacker can trigger a use-after-free error and perform a denial of service (DoS) attack.



20) Type Confusion (CVE-ID: CVE-2023-0286)

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

The vulnerability exists due to a type confusion error related to X.400 address processing inside an X.509 GeneralName. A remote attacker can pass specially crafted data to the application, trigger a type confusion error and perform a denial of service (DoS) attack or read memory contents.

In most cases, the attack requires the attacker to provide both the certificate chain and CRL, neither of which need to have a valid signature. If the attacker only controls one of these inputs, the other input must already contain an X.400 address as a CRL distribution point, which is uncommon. As such, this vulnerability is most likely to only affect applications which have implemented their own functionality for retrieving CRLs over a network.
