HYCU 4.8.1-274 security updates

This release contains fixes for the following vulnerabilities:

• RHSA-2023:3827:

  • CVE-2022-48281: A vulnerability was found in libtiff. This vulnerability occurs due to an issue in processCropSelections in the tools/tiffcrop.c function in LibTIFF that has a heap-based buffer overflow (for example, "WRITE of size 307203") via a crafted TIFF image.

• RHSA-2023:3839:

  • CVE-2023-1667: A NULL pointer dereference was found In libssh during re-keying with algorithm guessing. This issue may allow an authenticated client to cause a denial of service.
  • CVE-2023-2283: A vulnerability was found in libssh, where the authentication check of the connecting client can be bypassed in thepki_verify_data_signature function in memory allocation problems. This issue may happen if there is insufficient memory or the memory usage is limited. The problem is caused by the return value rc, which is initialized to SSH_ERROR and later rewritten to save the return value of the function call pki_key_check_hash_compatible. The value of the variable is not changed between this point and the cryptographic verification. Therefore any error between them calls goto error returning SSH_OK.

• RHSA-2023:3840:

  • CVE-2020-24736: A flaw was found in SQLite. A buffer overflow vulnerability allows a local attacker to cause a denial of service via a crafted script.

• RHSA-2023:3949:

  • CVE-2023-20867: A flaw was found in the open-vm-tools package. An attacker with root access privileges over ESXi may be able to cause an authentication bypass in the vgauth module. This may lead to compromised confidentiality and integrity.

• RHSA-2023:4102:

  • CVE-2023-2828: A vulnerability was found in BIND. The effectiveness of the cache-cleaning algorithm used in named can be severely diminished by querying the resolver for specific RRsets in a certain order, effectively allowing the configured max-cache-size limit to exceed significantly.

• RHSA-2023:4328:

  • CVE-2023-3347: A vulnerability was found in Samba's SMB2 packet signing mechanism. The SMB2 packet signing is not enforced if an admin configured "server signing = required" or for SMB2 connections to Domain Controllers where SMB2 packet signing is mandatory. This flaw allows an attacker to perform attacks, such as a man-in-the-middle attack, by intercepting the network traffic and modifying the SMB2 messages between client and server, affecting the integrity of the data.

• RHSA-2023:4419:

  • CVE-2023-38408: A vulnerability was found in OpenSSH. The PKCS#11 feature in the ssh-agent in OpenSSH has an insufficiently trustworthy search path, leading to remote code execution if an agent is forwarded to an attacker-controlled system (the code in /usr/lib is not necessarily safe for loading into ssh-agent). This flaw allows an attacker with control of the forwarded agent-socket on the server and the ability to write to the filesystem of the client host to execute arbitrary code with the privileges of the user running the ssh-agent.

• RHSA-2023:4498:

  • CVE-2023-34969: An assertion failure vulnerability was found in D-Bus. This issue occurs when a privileged monitoring connection (dbus-monitor, busctl monitor, gdbus monitor, or similar) is active, and a message from the bus driver cannot be delivered to a client connection due to rules or outgoing message quota. If a privileged user with control over the dbus-daemon is monitoring the message bus traffic using the Monitoring clients like the dbus-monitor or busctl monitor interfaces, then an unprivileged local user with the ability to connect to the same dbus-daemon could send specially crafted request, causing a dbus-daemon to crash, resulting in a denial of service under some circumstances.

• RHSA-2023:4520:

  • CVE-2023-32681: A flaw was found in the Python-requests package, where it is vulnerable to potentially leaking Proxy-Authorization headers to destination servers, specifically during redirects to an HTTPS origin. This is a product of how rebuild_proxies is used to recompute and reattach the Proxy-Authorization header to requests when redirected. This behavior only affects proxied requests when credentials are supplied in the URL user information component (for example, https://username:password@proxy:8080).

• RHSA-2023:4523:

  • CVE-2023-27536: A flaw was found in the Curl package. Libcurl keeps previously used connections in a connection pool for subsequent transfers to reuse if one of them matches the setup. However, the GSS delegation setting was left out from the configuration match checks, making them match too easily, affecting krb5/kerberos/negotiate/GSSAPI transfers.
  • CVE-2023-28321: A flaw was found in the Curl package. An incorrect International Domain Name (IDN) wildcard match may lead to improper certificate validation.

• RHSA-2023:4524:

  • CVE-2023-2602: A vulnerability was found in the pthread_create() function in libcap. This issue may allow a malicious actor to use cause __real_pthread_create() to return an error, which can exhaust the process memory.
  • CVE-2023-2603: A vulnerability was found in libcap. This issue occurs in the _libcap_strdup() function and can lead to an integer overflow if the input string is close to 4GiB.

• RHSA-2023:4529:

  • CVE-2023-28484: A NULL pointer dereference vulnerability was found in libxml2. This issue occurs when parsing (invalid) XML schemas.
  • CVE-2023-29469: A flaw was found in libxml2. This issue occurs when hashing empty strings which aren't null-terminated, xmlDictComputeFastKey could produce inconsistent results, which may lead to various logic or memory errors, including double free errors.

• RHSA-2023:4570:

  • CVE-2023-38403: An integer overflow flaw was found in the way iperf3 dynamically allocates memory buffers for JSON-formatted messages. A remote attacker could send a specially crafted sequence of bytes on the iperf3 control channel with a specified JSON message length of 0xffffffff to trigger an integer overflow leading the receiving process to abort due to heap corruption. This flaw allows an attacker to use a malicious client to cause a denial of service of an iperf3 server or potentially use a malicious server to cause connecting clients to crash.

• RHSA-2023:4864:

  • CVE-2023-32360: A vulnerability was found in OpenPrinting CUPS. Unauthorized users are permitted to fetch documents over local or remote networks, leading to confidentiality breach.

• RHSA-2023:5046:

  • CVE-2020-22219: A flaw was found in the libeconf library. This issue occurs due to a buffer overflow vulnerability in the bitwriter_grow_ function in FLAC that allows remote attackers to run arbitrary code via crafted input to the encoder.
