SB2024041657 - Multiple vulnerabilities in Oracle Communications Operations Monitor

Description

This security bulletin contains information about 4 secuirty vulnerabilities.

1) Use-after-free (CVE-ID: CVE-2023-5341)

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a use-after-free error within the ReadBMPImage() function in coders/bmp.c. A remote attacker can pass a specially crafted image to the application, 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.

2) Inadequate encryption strength (CVE-ID: CVE-2023-48795)

The vulnerability allows a remote attacker to perform MitM attack.

The vulnerability exists due to incorrect implementation of the SSH Binary Packet Protocol (BPP), which mishandles the handshake phase and the use of sequence numbers. A remote attacker can perform MitM attack and delete the SSH2_MSG_EXT_INFO message sent before authentication starts, allowing the attacker to disable a subset of the keystroke timing obfuscation features introduced in OpenSSH 9.5.

The vulnerability was dubbed "Terrapin attack" and it affects both client and server implementations.

3) NULL pointer dereference (CVE-ID: CVE-2023-49083)

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 calling the load_pem_pkcs7_certificates() or load_der_pkcs7_certificates() functions. A remote attacker can pass specially crafted PKCS7 blob/certificate certificate to the application and perform a denial of service (DoS) attack.

4) Heap-based buffer overflow (CVE-ID: CVE-2023-41056)

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

The vulnerability exists due to a boundary error when resizing memory buffers. A remote attacker can pass specially crafted data to the application, 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.
