A flaw in libtasn1 causes inefficient handling of specific certificate data. When processing a large number of elements in a certificate, libtasn1 takes much longer than expected, which can slow down or even crash the system. This flaw allows an attacker to send a specially crafted certificate, causing a denial of service attack. Affected products named by the advisory: Red Hat Enterprise Linux 8; Red Hat Enterprise Linux 8.4 Advanced Mission Critical Update Support; Red Hat Enterprise Linux 8.4 Extended Update Support Long-Life Add-On; Red Hat Enterprise Linux 8.6 Advanced Mission Critical Update Support; and 9 more. Affected products named by the advisory: Red Hat Enterprise Linux 8.6 Extended Update Support Long-Life Add-On; Red Hat Enterprise Linux 8.8 Telecommunications Update Service; Red Hat Enterprise Linux 8.8 Update Services for SAP Solutions; Red Hat Enterprise Linux 9.2 Update Services for SAP Solutions; and 4 more.
A flaw was found in the Submariner project. Due to unnecessary role-based access control permissions, a privileged attacker can run a malicious container on a node that may allow them to steal service account tokens and further compromise other nodes and potentially the entire cluster. Affected products named by the advisory: RHODF-4.16-RHEL-9; Red Hat Openshift Data Foundation 4.20; Red Hat Advanced Cluster Management for Kubernetes 2.
An integer overflow was found in the __vsyslog_internal function of the glibc library. This function is called by the syslog and vsyslog functions. This issue occurs when these functions are called with a very long message, leading to an incorrect calculation of the buffer size to store the message, resulting in undefined behavior. This issue affects glibc 2.37 and newer. This issue can only result in a memory allocation failure when the syslog function is called with a very long message, preventing the output of the message. This is the only known impact of this issue and this CVE was assigned to track this possibility. The glibc package, as shipped with Red Hat products, is not affected by this vulnerability because this issue was introduced in glibc 2.37, this glibc version is not used by any Red Hat product. Red Hat severity: Low — CVSS 5.3 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L). Weakness: CWE-190. Red Hat lists Red Hat Enterprise Linux 6; Red Hat Enterprise Linux 7; Red Hat Enterprise Linux 8; Red Hat Enterprise Linux 9 as not affected.
A flaw has been identified in glibc. In an extremely rare situation, the getaddrinfo function may access memory that has been freed, resulting in an application crash. This issue is only exploitable when a NSS module implements only the _nss_*_gethostbyname2_r and _nss_*_getcanonname_r hooks without implementing the _nss_*_gethostbyname3_r hook. The resolved name should return a large number of IPv6 and IPv4, and the call to the getaddrinfo function should have the AF_INET6 address family with AI_CANONNAME, AI_ALL and AI_V4MAPPED as flags. Affected products named by the advisory: Red Hat Enterprise Linux 8; Red Hat Enterprise Linux 8.6 Extended Update Support; Red Hat Enterprise Linux 9; Red Hat Virtualization 4 for Red Hat Enterprise Linux 8; and 1 more. Affected products named by the advisory: Red Hat Enterprise Linux 7.
A flaw was found in glibc. When the getaddrinfo function is called with the AF_UNSPEC address family and the system is configured with no-aaaa mode via /etc/resolv.conf, a DNS response via TCP larger than 2048 bytes can potentially disclose stack contents through the function returned address data, and may cause a crash. Affected products named by the advisory: Red Hat Enterprise Linux 8; Red Hat Enterprise Linux 9.
