SB2024071037 - Multiple vulnerabilities in IBM Storage Copy Data Management

Description

This security bulletin contains information about 14 secuirty vulnerabilities.

1) Improper certificate validation (CVE-ID: CVE-2023-28321)

The vulnerability allows a remote attacker to perform MitM attack.

The vulnerability exists due to improper certificate validation when matching wildcards in TLS certificates for IDN names. A remote attacker crate a specially crafted certificate that will be considered trusted by the library.

Successful exploitation of the vulnerability requires that curl is built to use OpenSSL, Schannel or Gskit.

2) Information disclosure (CVE-ID: CVE-2023-46218)

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to an error in curl that allows a malicious HTTP server to set "super cookies" that are then passed back to more origins than what is otherwise allowed or possible. A remote attacker can force curl to send such cookie to different and unrelated sites and domains.

3) Missing Encryption of Sensitive Data (CVE-ID: CVE-2023-46219)

The vulnerability allows a remote attacker to perform MitM attack.

The vulnerability exists due to an error when handling HSTS long file names. When saving HSTS data to an excessively long file name, curl can end up removing all contents from the file, making subsequent requests using that file unaware of the HSTS status they should otherwise use. As a result, a remote attacker can perform MitM attack.

4) Use-after-free (CVE-ID: CVE-2024-1086)

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

The vulnerability exists due to a use-after-free error within the netfilter nf_tables component in Linux kernel. A local user can trigger a use-after-free error and execute arbitrary code on the system.

5) Out-of-bounds write (CVE-ID: CVE-2023-6931)

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

The vulnerability exists due to a boundary error in the Linux kernel's Performance Events system component. A local user can trigger an out-of-bounds write and execute arbitrary code with elevated privileges.

6) Integer underflow (CVE-ID: CVE-2024-0565)

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

The vulnerability exists due to integer underflow within the receive_encrypted_standard() function in fs/smb/client/smb2ops.c in the SMB Client sub-component in the Linux Kernel. A remote attacker can trick the victim to connect to a malicious SMB server, trigger an integer underflow and execute arbitrary code on the target system.

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

7) Race condition (CVE-ID: CVE-2023-6546)

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

The vulnerability exists due to a race condition in the GSM 0710 tty multiplexor in the Linux kernel. A local user can exploit the race and gain unauthorized access to sensitive information and escalate privileges on the system.

8) Use-after-free (CVE-ID: CVE-2023-28319)

The vulnerability allows a remote attacker to gain access to sensitive information.

The vulnerability exists due to a use-after-free error when checking the SSH sha256 fingerprint. A remote attacker can use the application to connect to a malicious SSH server, trigger a use-after-free error and gain access to potentially sensitive information.

Successful exploitation of the vulnerability requires usage of the the CURLOPT_SSH_HOST_PUBLIC_KEY_SHA256 option, and also CURLOPT_VERBOSE or CURLOPT_ERRORBUFFER options have to be set.

9) Improper synchronization (CVE-ID: CVE-2023-28320)

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

The vulnerability exists due to improper synchronization when resolving host names using the alarm() and siglongjmp() function. A remote attacker can force the application to crash by influencing contents of the global buffer.

10) Expected behavior violation (CVE-ID: CVE-2023-28322)

The vulnerability allows a remote attacker to gain access to sensitive information.

The vulnerability exists due to a logic error when sending HTTP POST and PUT requests using the same handle. The libcurl can erroneously use the read callback (CURLOPT_READFUNCTION) to ask for data to send, even when the CURLOPT_POSTFIELDS option has been set, if the same handle previously was used to issue a PUT request which used that callback. As a result, the application can misbehave and either send off the wrong data or use memory after free or similar in the second transfer.

11) External control of file name or path (CVE-ID: CVE-2023-38546)

The vulnerability allows an attacker to inject arbitrary cookies into request.

The vulnerability exists due to the way cookies are handled by libcurl. If a transfer has cookies enabled when the handle is duplicated, the cookie-enable state is also cloned - but without cloning the actual cookies. If the source handle did not read any cookies from a specific file on disk, the cloned version of the handle would instead store the file name as none (using the four ASCII letters, no quotes).

Subsequent use of the cloned handle that does not explicitly set a source to load cookies from would then inadvertently load cookies from a file named none - if such a file exists and is readable in the current directory of the program using libcurl.

12) Heap-based buffer overflow (CVE-ID: CVE-2023-38545)

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

The vulnerability exists due to a boundary error in the SOCKS5 proxy handshake. A remote attacker can trick the victim to visit a malicious website, 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 but requires that SOCKS5 proxy is used and that SOCKS5 handshake is slow (e.g. under heavy load or DoS attack).

13) Use-after-free (CVE-ID: CVE-2023-51042)

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

The vulnerability exists due to a use-after-free error within the amdgpu_cs_wait_all_fences() function in drivers/gpu/drm/amd/amdgpu/amdgpu_cs.c. A local user can trigger a use-after-free error and execute arbitrary code with elevated privileges.

14) NULL pointer dereference (CVE-ID: CVE-2022-38096)

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

The vulnerability exists due to a NULL pointer dereference error in vmwgfx driver in drivers/gpu/vmxgfx/vmxgfx_execbuf.c in GPU component of Linux kernel with device file '/dev/dri/renderD128 (or Dxxx)'. A local user can perform a denial of service (DoS) attack.
