A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.Description:The redhat-virtualization-host packages provide the Red Hat Virtualization Host. These packages include redhat-release-virtualization-host, ovirt-node, and rhev-hypervisor. Red Hat Virtualization Hosts (RHVH) are installed using a special build of Red Hat Enterprise Linux with only the packages required to host virtual machines. RHVH features a Cockpit user interface for monitoring the host's resources and performing administrative tasks.Security Fix(es):For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.Solution:https://access.redhat.com/articles/2974891CVEs:CVE-2023-4911References:https://access.redhat.com/security/updates/classification/#moderatehttps://bugzilla.redhat.com/show_bug.cgi?id=2238352Related news
Red Hat uses a four-point impact scale to classify security issues affecting our products. Have you ever asked yourself what it takes and what the requirements are for each point of the scale? We will talk through the highlights of our process in this article.Is this a CVE?First and foremost, what is a CVE? Short for Common Vulnerabilities and Exposures, it is a list of publicly disclosed computer security flaws. Learn more in this Red Hat post.To receive a severity rating, the issue needs to be a CVE. But what does it take to be a CVE? In order to warrant a CVE ID, a vulnerability has to comp
Malicious local attackers can obtain full root access on Linux machines by taking advantage of a newly disclosed security flaw in the GNU C library (aka glibc). Tracked as CVE-2023-6246, the heap-based buffer overflow vulnerability is rooted in glibc's __vsyslog_internal() function, which is used by syslog() and vsyslog() for system logging purposes. It's said to have been accidentally
A buffer overflow exists in the GNU C Library's dynamic loader ld.so while processing the GLIBC_TUNABLES environment variable. It has been dubbed Looney Tunables. This issue allows an local attacker to use maliciously crafted GLIBC_TUNABLES when launching binaries with SUID permission to execute code in the context of the root user. This Metasploit module targets glibc packaged on Ubuntu and Debian. Fedora 37 and 38 and other distributions of linux also come packaged with versions of glibc vulnerable to CVE-2023-4911 however this module does not target them.
By Deeba Ahmed Patches for all affected versions of Apache ActiveMQ have been released, and clients are strongly advised to upgrade their systems. This is a post from HackRead.com Read the original post: Kinsing Crypto Malware Targets Linux Systems via Apache ActiveMQ Flaw
Hello everyone! October was an interesting and busy month for me. I started a new job, worked on my open source Vulristics project, and analyzed vulnerabilities using it. Especially Linux vulnerabilities as part of my new Linux Patch Wednesday project. And, of course, analyzed Microsoft Patch Tuesday as well. In addition, at the end of […]
The threat actors linked to Kinsing have been observed attempting to exploit the recently disclosed Linux privilege escalation flaw called Looney Tunables as part of a "new experimental campaign" designed to breach cloud environments. "Intriguingly, the attacker is also broadening the horizons of their cloud-native attacks by extracting credentials from the Cloud Service Provider (CSP)," cloud
Red Hat Security Advisory 2023-5476-01 - The glibc packages provide the standard C libraries, POSIX thread libraries, standard math libraries, and the name service cache daemon used by multiple programs on the system. Without these libraries, the Linux system cannot function correctly. Issues addressed include buffer overflow and privilege escalation vulnerabilities.
Red Hat Security Advisory 2023-5455-01 - The glibc packages provide the standard C libraries, POSIX thread libraries, standard math libraries, and the name service cache daemon used by multiple programs on the system. Without these libraries, the Linux system cannot function correctly. Issues addressed include buffer overflow, privilege escalation, and use-after-free vulnerabilities.
Red Hat Security Advisory 2023-5454-01 - The glibc packages provide the standard C libraries, POSIX thread libraries, standard math libraries, and the name service cache daemon used by multiple programs on the system. Without these libraries, the Linux system cannot function correctly. Issues addressed include buffer overflow and privilege escalation vulnerabilities.
Debian Linux Security Advisory 5514-1 - The Qualys Research Labs discovered a buffer overflow in the dynamic loader's processing of the GLIBC_TUNABLES environment variable. An attacker can exploit this flaw for privilege escalation.
A new Linux security vulnerability dubbed Looney Tunables has been discovered in the GNU C library's ld.so dynamic loader that, if successfully exploited, could lead to a local privilege escalation and allow a threat actor to gain root privileges. Tracked as CVE-2023-4911 (CVSS score: 7.8), the issue is a buffer overflow that resides in the dynamic loader's processing of the GLIBC_TUNABLES
A buffer overflow was discovered in the GNU C Library's dynamic loader ld.so while processing the GLIBC_TUNABLES environment variable. This issue could allow a local attacker to use maliciously crafted GLIBC_TUNABLES environment variables when launching binaries with SUID permission to execute code with elevated privileges.
