CVE-2023-4004 5 Debian, Fedoraproject, Linux and 2 more 8 Debian Linux, Fedora, Linux Kernel and 5 more 2023-12-29 N/A 7.8 HIGH
A use-after-free flaw was found in the Linux kernel's netfilter in the way a user triggers the nft_pipapo_remove function with the element, without a NFT_SET_EXT_KEY_END. This issue could allow a local user to crash the system or potentially escalate their privileges on the system.
CVE-2023-2680 2 Qemu, Redhat 2 Qemu, Enterprise Linux 2023-12-28 N/A 8.2 HIGH
This CVE exists because of an incomplete fix for CVE-2021-3750. More specifically, the qemu-kvm package as released for Red Hat Enterprise Linux 9.1 via RHSA-2022:7967 included a version of qemu-kvm that was actually missing the fix for CVE-2021-3750.
CVE-2023-38200 3 Fedoraproject, Keylime, Redhat 9 Fedora, Keylime, Enterprise Linux and 6 more 2023-12-28 N/A 7.5 HIGH
A flaw was found in Keylime. Due to their blocking nature, the Keylime registrar is subject to a remote denial of service against its SSL connections. This flaw allows an attacker to exhaust all available connections.
CVE-2004-0079 23 4d, Apple, Avaya and 20 more 66 Webstar, Mac Os X, Mac Os X Server and 63 more 2023-12-28 5.0 MEDIUM 7.5 HIGH
The do_change_cipher_spec function in OpenSSL 0.9.6c to 0.9.6k, and 0.9.7a to 0.9.7c, allows remote attackers to cause a denial of service (crash) via a crafted SSL/TLS handshake that triggers a null dereference.
CVE-2023-6563 1 Redhat 6 Enterprise Linux, Keycloak, Openshift Container Platform and 3 more 2023-12-27 N/A 7.7 HIGH
An unconstrained memory consumption vulnerability was discovered in Keycloak. It can be triggered in environments which have millions of offline tokens (> 500,000 users with each having at least 2 saved sessions). If an attacker creates two or more user sessions and then open the "consents" tab of the admin User Interface, the UI attempts to load a huge number of offline client sessions leading to excessive memory and CPU consumption which could potentially crash the entire system.
CVE-2021-43860 4 Debian, Fedoraproject, Flatpak and 1 more 4 Debian Linux, Fedora, Flatpak and 1 more 2023-12-23 6.8 MEDIUM 8.6 HIGH
Flatpak is a Linux application sandboxing and distribution framework. Prior to versions 1.12.3 and 1.10.6, Flatpak doesn't properly validate that the permissions displayed to the user for an app at install time match the actual permissions granted to the app at runtime, in the case that there's a null byte in the metadata file of an app. Therefore apps can grant themselves permissions without the consent of the user. Flatpak shows permissions to the user during install by reading them from the "xa.metadata" key in the commit metadata. This cannot contain a null terminator, because it is an untrusted GVariant. Flatpak compares these permissions to the *actual* metadata, from the "metadata" file to ensure it wasn't lied to. However, the actual metadata contents are loaded in several places where they are read as simple C-style strings. That means that, if the metadata file includes a null terminator, only the content of the file from *before* the terminator gets compared to xa.metadata. Thus, any permissions that appear in the metadata file after a null terminator are applied at runtime but not shown to the user. So maliciously crafted apps can give themselves hidden permissions. Users who have Flatpaks installed from untrusted sources are at risk in case the Flatpak has a maliciously crafted metadata file, either initially or in an update. This issue is patched in versions 1.12.3 and 1.10.6. As a workaround, users can manually check the permissions of installed apps by checking the metadata file or the xa.metadata key on the commit metadata.
CVE-2023-5157 3 Fedoraproject, Mariadb, Redhat 12 Fedora, Mariadb, Enterprise Linux and 9 more 2023-12-22 N/A 7.5 HIGH
A vulnerability was found in MariaDB. An OpenVAS port scan on ports 3306 and 4567 allows a malicious remote client to cause a denial of service.
CVE-2021-4104 4 Apache, Fedoraproject, Oracle and 1 more 46 Log4j, Fedora, Advanced Supply Chain Planning and 43 more 2023-12-22 6.0 MEDIUM 7.5 HIGH
JMSAppender in Log4j 1.2 is vulnerable to deserialization of untrusted data when the attacker has write access to the Log4j configuration. The attacker can provide TopicBindingName and TopicConnectionFactoryBindingName configurations causing JMSAppender to perform JNDI requests that result in remote code execution in a similar fashion to CVE-2021-44228. Note this issue only affects Log4j 1.2 when specifically configured to use JMSAppender, which is not the default. Apache Log4j 1.2 reached end of life in August 2015. Users should upgrade to Log4j 2 as it addresses numerous other issues from the previous versions.
CVE-2023-4853 2 Quarkus, Redhat 13 Quarkus, Build Of Optaplanner, Build Of Quarkus and 10 more 2023-12-21 N/A 8.1 HIGH
A flaw was found in Quarkus where HTTP security policies are not sanitizing certain character permutations correctly when accepting requests, resulting in incorrect evaluation of permissions. This issue could allow an attacker to bypass the security policy altogether, resulting in unauthorized endpoint access and possibly a denial of service.
CVE-2019-14835 8 Canonical, Debian, Fedoraproject and 5 more 44 Ubuntu Linux, Debian Linux, Fedora and 41 more 2023-12-15 7.2 HIGH 7.8 HIGH
A buffer overflow flaw was found, in versions from 2.6.34 to 5.2.x, in the way Linux kernel's vhost functionality that translates virtqueue buffers to IOVs, logged the buffer descriptors during migration. A privileged guest user able to pass descriptors with invalid length to the host when migration is underway, could use this flaw to increase their privileges on the host.
CVE-2023-46848 2 Redhat, Squid-cache 5 Enterprise Linux, Enterprise Linux Eus, Enterprise Linux Server Aus and 2 more 2023-12-14 N/A 7.5 HIGH
Squid is vulnerable to Denial of Service, where a remote attacker can perform DoS by sending ftp:// URLs in HTTP Request messages or constructing ftp:// URLs from FTP Native input.
CVE-2022-46344 4 Debian, Fedoraproject, Redhat and 1 more 4 Debian Linux, Fedora, Enterprise Linux and 1 more 2023-12-13 N/A 8.8 HIGH
A vulnerability was found in X.Org. This security flaw occurs because the handler for the XIChangeProperty request has a length-validation issues, resulting in out-of-bounds memory reads and potential information disclosure. This issue can lead to local privileges elevation on systems where the X server is running privileged and remote code execution for ssh X forwarding sessions.
CVE-2023-5557 2 Gnome, Redhat 2 Tracker Miners, Enterprise Linux 2023-12-12 N/A 7.7 HIGH
A flaw was found in the tracker-miners package. A weakness in the sandbox allows a maliciously-crafted file to execute code outside the sandbox if the tracker-extract process has first been compromised by a separate vulnerability.
CVE-2023-44488 4 Debian, Fedoraproject, Redhat and 1 more 4 Debian Linux, Fedora, Enterprise Linux and 1 more 2023-12-10 N/A 7.5 HIGH
VP9 in libvpx before 1.13.1 mishandles widths, leading to a crash related to encoding.
CVE-2023-3972 1 Redhat 19 Enterprise Linux, Enterprise Linux Aus, Enterprise Linux Desktop and 16 more 2023-12-10 N/A 7.8 HIGH
A vulnerability was found in insights-client. This security issue occurs because of insecure file operations or unsafe handling of temporary files and directories that lead to local privilege escalation. Before the insights-client has been registered on the system by root, an unprivileged local user or attacker could create the /var/tmp/insights-client directory (owning the directory with read, write, and execute permissions) on the system. After the insights-client is registered by root, an attacker could then control the directory content that insights are using by putting malicious scripts into it and executing arbitrary code as root (trivially bypassing SELinux protections because insights processes are allowed to disable SELinux system-wide).
CVE-2023-4147 4 Debian, Fedoraproject, Linux and 1 more 8 Debian Linux, Fedora, Linux Kernel and 5 more 2023-12-10 N/A 7.8 HIGH
A use-after-free flaw was found in the Linux kernel’s Netfilter functionality when adding a rule with NFTA_RULE_CHAIN_ID. This flaw allows a local user to crash or escalate their privileges on the system.
CVE-2023-1108 2 Netapp, Redhat 17 Oncommand Workflow Automation, Build Of Quarkus, Decision Manager and 14 more 2023-12-10 N/A 7.5 HIGH
A flaw was found in undertow. This issue makes achieving a denial of service possible due to an unexpected handshake status updated in SslConduit, where the loop never terminates.
CVE-2023-3640 2 Linux, Redhat 2 Linux Kernel, Enterprise Linux 2023-12-10 N/A 7.8 HIGH
A possible unauthorized memory access flaw was found in the Linux kernel's cpu_entry_area mapping of X86 CPU data to memory, where a user may guess the location of exception stacks or other important data. Based on the previous CVE-2023-0597, the 'Randomize per-cpu entry area' feature was implemented in /arch/x86/mm/cpu_entry_area.c, which works through the init_cea_offsets() function when KASLR is enabled. However, despite this feature, there is still a risk of per-cpu entry area leaks. This issue could allow a local user to gain access to some important data with memory in an expected location and potentially escalate their privileges on the system.
CVE-2023-1476 2 Linux, Redhat 6 Linux Kernel, Enterprise Linux, Enterprise Linux Eus and 3 more 2023-12-10 N/A 7.0 HIGH
A use-after-free flaw was found in the Linux kernel’s mm/mremap memory address space accounting source code. This issue occurs due to a race condition between rmap walk and mremap, allowing a local user to crash the system or potentially escalate their privileges on the system.
