SB2024061832 - Multiple vulnerabilities in Red Hat OpenShift Container Platform 4.12

Description

This security bulletin contains information about 12 secuirty vulnerabilities.

1) Cleartext storage of sensitive information (CVE-ID: CVE-2023-30841)

The  vulnerability allows a local user to gain access to sensitive information.

The vulnerability exists due to ironic and ironic-inspector deployed within Baremetal Operator using the included `deploy.sh` store their `.htpasswd` files as ConfigMaps instead of Secrets. A local user can obtain credentials and use them to compromise the application.

2) Integer overflow (CVE-ID: CVE-2021-43618)

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

The vulnerability exists due to integer overflow in mpz/inp_raw.c. A remote attacker can pass specially crafted data to the application, trigger integer overflow and cause a denial of service condition on the target system.

3) OS Command Injection (CVE-ID: CVE-2023-6004)

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

The vulnerability exists due to improper input validation in OpenSSH client. If an invalid user or hostname that contained shell metacharacters was passed to ssh(1), and a ProxyCommand, LocalCommand directive or "match exec" predicate referenced the user or hostname via %u, %h or similar expansion token, then an attacker who could supply arbitrary user/hostnames to ssh(1) could potentially perform command injection depending on what quoting was present in the user-supplied ssh_config(5) directive.

4) Unchecked Return Value (CVE-ID: CVE-2023-6918)

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

The vulnerability exists due to libssh does not check for returned values of message digest (MD) operations in low memory conditions. A remote attacker can terminate the connection or force the library to use weak keys.

5) Insufficient verification of data authenticity (CVE-ID: CVE-2023-7008)

The vulnerability allows a remote attacker to perform a MitM attack.

The vulnerability exists due to systemd-resolved accepts records of DNSSEC-signed domains even when they have no signature. A remote attacker can perform MitM attack.

6) 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.

7) 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.

8) 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.

9) Buffer overflow (CVE-ID: CVE-2024-2961)

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

The vulnerability exists due to a boundary error within the iconv() function when converting string to the ISO-2022-CN-EXT character set. A remote attacker can pass specially crafted input to the application, trigger a 4 byte buffer overflow and execute arbitrary code on the target system.

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

10) Memory leak (CVE-ID: CVE-2024-26458)

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

The vulnerability exists due to memory leak in /krb5/src/lib/rpc/pmap_rmt.c. A remote attacker can perform a denial of service attack.

11) Memory leak (CVE-ID: CVE-2024-26461)

The vulnerability allows a remote attacker to perform DoS attack on the target system.

The vulnerability exists due memory leak in /krb5/src/lib/gssapi/krb5/k5sealv3.c. A remote attacker can force the application to leak memory and perform denial of service attack.

12) Cryptographic issues (CVE-ID: CVE-2024-28834)

The vulnerability allows a remote attacker to perform MitM attack.

The vulnerability exists due to a side-channel attack when using the gnutls_privkey_sign_data2 API function with the "GNUTLS_PRIVKEY_FLAG_REPRODUCIBLE" flag. A remote attacker can launch Minerva attack and gain access to sensitive information.
