Description

This security bulletin contains information about 8 secuirty vulnerabilities.


1) Improper input validation (CVE-ID: CVE-2021-3426)

The vulnerability allows a remote authenticated user to gain access to sensitive information.

The vulnerability exists due to improper input validation within the Binding Support Function (Python) component in Oracle Communications Cloud Native Core Binding Support Function. A remote authenticated user can exploit this vulnerability to gain access to sensitive information.


2) Use of a broken or risky cryptographic algorithm (CVE-ID: CVE-2021-40528)

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

The vulnerability exists due to use of a broken or risky cryptographic algorithm in the ElGamal implementation. A remote attacker can gain unauthorized access to sensitive information on the system.


3) Integer overflow (CVE-ID: CVE-2022-29824)

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

The vulnerability exists due to integer overflow in several buffer handling functions in buf.c (xmlBuf*) and tree.c (xmlBuffer*). A remote attacker can pass specially crafted multi-gigabyte XML file to the application, trigger integer overflow and execute arbitrary code on the target system.

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


4) Buffer overflow (CVE-ID: CVE-2018-25032)

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 when compressing data. A remote attacker can pass specially crafted input to the application, trigger memory corruption and perform a denial of service (DoS) attack.


5) Inconsistent interpretation of HTTP requests (CVE-ID: CVE-2022-24761)

The vulnerability allows a remote attacker to preform HTTP request smuggling attacks.

The vulnerability exists due to improper validating if the incoming HTTP request matches the RFC7230 standard. A remote attacker can send a specially crafted HTTP request to the server and smuggle arbitrary HTTP headers.

Successful exploitation of vulnerability may allow an attacker to poison HTTP cache and perform phishing attacks.


6) Incorrect Implementation of Authentication Algorithm (CVE-ID: CVE-2022-27782)

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

The vulnerability exists due to the way libcurl handles previously used connections in a connection pool for subsequent transfers. Several TLS and SSH settings were left out from the configuration match checks, resulting in erroneous matches for different resources. As a result, libcurl can send authentication string from one resource to another, exposing credentials to a third-party.


7) Path traversal (CVE-ID: CVE-2022-24785)

The vulnerability allows a remote attacker to perform directory traversal attacks.

The vulnerability exists due to input validation error when processing directory traversal sequences within the npm version of Moment.js. A remote attacker can send a specially crafted HTTP request and read arbitrary files on the system.


8) Use-after-free (CVE-ID: CVE-2022-1154)

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a use-after-free error within the utf_ptr2char() function in regexp_bt.c. 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.
