SB2023101144 - Multiple vulnerabilities in IBM QRadar Network Packet Capture

Description

This security bulletin contains information about 7 secuirty vulnerabilities.

1) Untrusted search path (CVE-ID: CVE-2023-38408)

The vulnerability allows a remote attacker to compromise the affected system.

The vulnerability exists due to usage of an insecure search path within the PKCS#11 feature in ssh-agent. A remote attacker can trick the victim into connecting to a malicious SSH server and execute arbitrary code on the system, if an agent is forwarded to an attacker-controlled system.

Note, this vulnerability exists due to incomplete fix for #VU2015 (CVE-2016-10009).

2) Heap-based buffer overflow (CVE-ID: CVE-2022-37434)

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

The vulnerability exists due to a boundary error when processing a large gzip header within inflateGetHeader in inflate.c. A remote attacker can pass a specially crafted file to the affected application, trigger heap-based buffer overflow and execute arbitrary code on the target system.

3) Out-of-bounds write (CVE-ID: CVE-2023-0767)

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a boundary error when processing PKCS 12 Safe Bag attributes. A remote attacker can create a specially crafted PKCS 12 cert bundle, trick the victim into loading it, trigger an out-of-bounds write and execute arbitrary code on the target system.

4) Stack-based buffer overflow (CVE-ID: CVE-2022-4378)

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

The vulnerability exists due to a boundary error within the __do_proc_dointvec() function. A local user can trigger a stack-based buffer overflow and execute arbitrary code with elevated privileges.

5) Use-after-free (CVE-ID: CVE-2022-42703)

The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to a use-after-free error within the mm/rmap.c in the Linux kernel, related to leaf anon_vma double reuse. A local user can trigger a use-after-free error and crash the kernel.

6) Type Confusion (CVE-ID: CVE-2023-0286)

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

The vulnerability exists due to a type confusion error related to X.400 address processing inside an X.509 GeneralName. A remote attacker can pass specially crafted data to the application, trigger a type confusion error and perform a denial of service (DoS) attack or read memory contents.

In most cases, the attack requires the attacker to provide both the certificate chain and CRL, neither of which need to have a valid signature. If the attacker only controls one of these inputs, the other input must already contain an X.400 address as a CRL distribution point, which is uncommon. As such, this vulnerability is most likely to only affect applications which have implemented their own functionality for retrieving CRLs over a network.

7) Input validation error (CVE-ID: CVE-2023-22809)

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

The vulnerability exists within the sudoedit (aka -e) feature due to insufficient validation of user-supplied input passed in the user-provided environment variables (SUDO_EDITOR, VISUAL, and EDITOR). The problem exists because a user-specified editor may contain a "--" argument that defeats a protection mechanism, e.g., an EDITOR='vim -- /path/to/extra/file' value. A local user can append arbitrary entries to the list of files to process and escalate privileges on the system.
