SB20230418121 - Multiple vulnerabilities in Oracle Communications Cloud Native Core Binding Support Function

Description

This security bulletin contains information about 5 secuirty vulnerabilities.

1) Input validation error (CVE-ID: CVE-2022-41966)

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

The vulnerability exists due to insufficient validation of user-supplied XML input. A remote attacker can pass specially crafted data to the application, trigger a stack overflow error and perform a denial of service (DoS) attack.

2) Infinite loop (CVE-ID: CVE-2022-41881)

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

The vulnerability exists due to infinite loop within the HaProxyMessageDecoder when parsing a TLV with type of "PP2_TYPE_SSL". A remote attacker can pass a specially crafted message to consume all available system resources and cause denial of service conditions.

3) Code Injection (CVE-ID: CVE-2022-45143)

The vulnerability allows a remote attacker to manipulate server output.

The vulnerability exists due to improper input validation within the JsonErrorReportValve when handling type, message or description values. A remote attacker can send a specially crafted request and manipulate or invalidate JSON output.

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

4) Out-of-bounds write (CVE-ID: CVE-2022-40151)

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

The vulnerability exists due to a boundary error when processing untrusted input in the Woodstox XML parser. A remote attacker can pass a specially crafted input to the parser, trigger an out-of-bounds write and execute arbitrary code on the target system.

5) Resource management error (CVE-ID: CVE-2022-40304)

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

The vulnerability exists in entities.c due to the way libxml2 handles reference cycles. The library does not anticipate that entity content can be allocated from a dict and clears it upon reference cycle detection by setting its first byte to zero. This can lead to memory corruption  issues, such as double free errors and result in a denial of service.
