SB2024041659 - Multiple vulnerabilities in Oracle Communications Cloud Native Core Policy

Description

This security bulletin contains information about 9 secuirty vulnerabilities.

1) Out-of-bounds write (CVE-ID: CVE-2023-4016)

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

The vulnerability exists due to a boundary error when processing untrusted input. A local user can trigger an out-of-bounds write and execute arbitrary code with elevated privileges.

2) Stack-based buffer overflow (CVE-ID: CVE-2023-51074)

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

The vulnerability exists due to a boundary error in the Criteria.parse() method. A remote unauthenticated attacker can trigger stack-based buffer overflow and perform a denial of service attack.

3) Information disclosure (CVE-ID: CVE-2023-4641)

The vulnerability allows a local user to gain access to potentially sensitive information.

The vulnerability exists due to an error in gpasswd(1), which fails to clean memory properly. When asking for a new password, shadow-utils asks the password twice. If the password fails on the second attempt, shadow-utils fails in cleaning the buffer used to store the first entry. A local user with enough access can retrieve the password from the memory.

4) Resource exhaustion (CVE-ID: CVE-2024-26308)

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

The vulnerability exists due to application does not properly control consumption of memory when unpacking a broken Pack200 file. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.

5) Inconsistent interpretation of HTTP requests (CVE-ID: CVE-2023-46589)

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

The vulnerability exists due to improper validation of HTTP requests when parsing malformed trailer headers. 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) Resource exhaustion (CVE-ID: CVE-2023-44487)

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

The vulnerability exists due to improperly control of consumption for internal resources when handling HTTP/2 requests with compressed HEADERS frames. A remote attacker can send a sequence of compressed HEADERS frames followed by RST_STREAM frames and perform a denial of service (DoS) attack, a.k.a. "Rapid Reset".

Note, the vulnerability is being actively exploited in the wild.

7) Resource exhaustion (CVE-ID: CVE-2024-22201)

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

The vulnerability exists due to application does not properly control consumption of internal resources when handling HTTP/2 connections. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.

8) NULL pointer dereference (CVE-ID: CVE-2024-26130)

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

The vulnerability exists due to a NULL pointer dereference error within pkcs12.serialize_key_and_certificates when called with a non-matching certificate and private key and an hmac_hash override. A remote attacker can pass specially crafted data to the application and perform a denial of service (DoS) attack.

9) Improper access control (CVE-ID: CVE-2024-22257)

The vulnerability allows a remote attacker to gain unauthorized access to otherwise restricted functionality.

The vulnerability exists due to improper access restrictions when the "AuthenticatedVoter#vote" passing a "null" Authentication parameter. A remote attacker can bypass implemented security restrictions and gain unauthorized access to the application.
