Red Hat Security Advisory: security update Logging for Red Hat OpenShift - 5.8.6

Moderate

A use-after-free flaw was found in the Linux kernel’s nftables sub-component due to a race problem between the set GC and transaction in the Linux Kernel. This flaw allows a local attacker to crash the system due to a missing call to `nft_set_elem_mark_busy`, causing double deactivation of the element and possibly leading to a kernel information leak problem.

CWE-416 - Use After Free

A flaw was found in OpenSSL in how it processes key and initialization vector (IV) lengths. This issue can lead to potential truncation or overruns during the initialization of some symmetric ciphers. A truncation in the IV can result in non-uniqueness, which could result in loss of confidentiality for some cipher modes. Both truncations and overruns of the key and the IV will produce incorrect results and could, in some cases, trigger a memory exception.

CWE-325 - Missing Cryptographic Step

A flaw was found in the Linux kernel's Performance Events system component. A condition can be triggered that allows data to be written past the end or before the beginning of the intended memory buffer. This issue may lead to a system crash, code execution, or local privilege escalation.

CWE-787 - Out-of-bounds Write

A vulnerability was found that the response times to malformed ciphertexts in RSA-PSK ClientKeyExchange differ from response times of ciphertexts with correct PKCS#1 v1.5 padding.

CWE-203 - Observable Discrepancy

A flaw was found in the Linux kernel's NVMe driver. This issue may allow an unauthenticated malicious actor to send a set of crafted TCP packages when using NVMe over TCP, leading the NVMe driver to a NULL pointer dereference in the NVMe driver and causing kernel panic and a denial of service.

CWE-476 - NULL Pointer Dereference

A flaw was found in the Linux kernel's NVMe driver. This issue may allow an unauthenticated malicious actor to send a set of crafted TCP packages when using NVMe over TCP, leading the NVMe driver to a NULL pointer dereference in the NVMe driver, causing kernel panic and a denial of service.

CWE-476 - NULL Pointer Dereference

A flaw was found in the Linux kernel's NVMe driver. This issue may allow an unauthenticated malicious actor to send a set of crafted TCP packages when using NVMe over TCP, leading the NVMe driver to a NULL pointer dereference in the NVMe driver, causing kernel panic and a denial of service.

CWE-476 - NULL Pointer Dereference

An out-of-bounds read vulnerability was found in smbCalcSize in fs/smb/client/netmisc.c in the Linux Kernel. This issue could allow a local attacker to crash the system or leak internal kernel information.

CWE-125 - Out-of-bounds Read

An out-of-bounds read vulnerability was found in smb2_dump_detail in fs/smb/client/smb2ops.c in the Linux Kernel. This issue could allow a local attacker to crash the system or leak internal kernel information.

CWE-125 - Out-of-bounds Read

A use-after-free flaw was found in the Netfilter subsystem in the Linux kernel via the nft_pipapo_walk function. This issue may allow a local user with CAP_NET_ADMIN capability to trigger an application crash, information disclosure, or local privilege escalation.

CWE-416 - Use After Free

A flaw was found in curl that verifies a given cookie domain against the Public Suffix List. This issue could allow a malicious HTTP server to set "super cookies" in curl that are passed back to more origins than what is otherwise allowed or possible.

CWE-201 - Insertion of Sensitive Information Into Sent Data
