Description

This security bulletin contains information about 13 secuirty vulnerabilities.


1) Security features bypass (CVE-ID: CVE-2023-4039)

The vulnerability allows a remote attacker to bypass implemented security restrictions.

The vulnerability exists due to the GCC's stack smashing protection does not detect or defend against overflows of dynamically-sized local variables on AArch64 targets. A remote attacker can bypass expected security restrictions and successfully exploit buffer overflow vulnerabilities.


2) Security features bypass (CVE-ID: CVE-2022-24329)

The vulnerability allows a remote user to bypass certain security restrictions.

The vulnerability exists due to unspecified error, related to the ability to lock dependencies for Kotlin Multiplatform Gradle projects.



3) NULL pointer dereference (CVE-ID: CVE-2023-28484)

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

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


4) Input validation error (CVE-ID: CVE-2023-20863)

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. A remote user can use a specially crafted SpEL expression and perform a denial of service (DoS) attack.


5) Resource exhaustion (CVE-ID: CVE-2023-34462)

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 if no idle timeout handler was configured. A remote attacker can send a client hello packet, which leads the server to buffer up to 16MB of data per connection and results in a denial of service condition.


6) Incorrect default permissions (CVE-ID: CVE-2023-2976)

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

The vulnerability exists due to incorrect default permissions in com.google.common.io.FileBackedOutputStream. A local user with access to the system can view contents of files and directories or modify them.


7) Improper Certificate Validation (CVE-ID: CVE-2022-4492)

The vulnerability allows a remote attacker to perform MitM attack.

The vulnerability exists due to the undertow client does not check the server identity presented by the server certificate in https connections. A remote attacker can perform MitM attack.


8) Incorrect Conversion between Numeric Types (CVE-ID: CVE-2023-3635)

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

The vulnerability exists due to GzipSource does not handle an exception that might be raised when parsing a malformed gzip buffer. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.


9) Resource management error (CVE-ID: CVE-2023-20883)

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

The vulnerability exists due to improper management of internal resources within the application. A remote attacker can pass specially crafted data to the application and perform a denial of service (DoS) attack.

Specifically, an application is vulnerable if all of the conditions are true:

  • The application has Spring MVC auto-configuration enabled. This is the case by default if Spring MVC is on the classpath.
  • The application makes use of Spring Boot's welcome page support, either static or templated.
  • Your application is deployed behind a proxy which caches 404 responses.


10) Out-of-bounds write (CVE-ID: CVE-2023-35788)

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

The vulnerability exists due to a boundary error within the fl_set_geneve_opt() function in net/sched/cls_flower.c in Linux kernel. A local user can trigger an out-of-bounds write and execute arbitrary code with elevated privileges.


11) Buffer overflow (CVE-ID: CVE-2023-29491)

The vulnerability allows a local user to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error when processing malformed data in a terminfo database file. A local user can trigger memory corruption and execute arbitrary code on the target system.



12) Improper input validation (CVE-ID: CVE-2021-41945)

The vulnerability allows a remote non-authenticated attacker to read and manipulate data.

The vulnerability exists due to improper input validation within the Install/Upgrade (HTTPX) component in Oracle Communications Cloud Native Core Policy. A remote non-authenticated attacker can exploit this vulnerability to read and manipulate data.


13) Security features bypass (CVE-ID: CVE-2023-34034)

The vulnerability allows a remote attacker to bypass security restrictions.

The vulnerability exists due to the usage of "**" as a pattern in Spring Security configuration for WebFlux creates a mismatch in pattern matching between Spring Security and Spring WebFlux. A remote unauthenticated attacker can trigger the vulnerability to bypass security restrictions.
