CVE-2023-2008 2 Linux, Redhat 3 Linux Kernel, Enterprise Linux, Rhel Eus 2024-08-02 7.8 High
A flaw was found in the Linux kernel's udmabuf device driver. The specific flaw exists within a fault handler. The issue results from the lack of proper validation of user-supplied data, which can result in a memory access past the end of an array. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of the kernel.
CVE-2023-1998 3 Debian, Linux, Redhat 5 Debian Linux, Linux Kernel, Enterprise Linux and 2 more 2024-08-02 5.6 Medium
The Linux kernel allows userspace processes to enable mitigations by calling prctl with PR_SET_SPECULATION_CTRL which disables the speculation feature as well as by using seccomp. We had noticed that on VMs of at least one major cloud provider, the kernel still left the victim process exposed to attacks in some cases even after enabling the spectre-BTI mitigation with prctl. The same behavior can be observed on a bare-metal machine when forcing the mitigation to IBRS on boot command line. This happened because when plain IBRS was enabled (not enhanced IBRS), the kernel had some logic that determined that STIBP was not needed. The IBRS bit implicitly protects against cross-thread branch target injection. However, with legacy IBRS, the IBRS bit was cleared on returning to userspace, due to performance reasons, which disabled the implicit STIBP and left userspace threads vulnerable to cross-thread branch target injection against which STIBP protects.
CVE-2023-1981 3 Avahi, Fedoraproject, Redhat 3 Avahi, Fedora, Enterprise Linux 2024-08-02 5.5 Medium
A vulnerability was found in the avahi library. This flaw allows an unprivileged user to make a dbus call, causing the avahi daemon to crash.
CVE-2023-1945 2 Mozilla, Redhat 7 Firefox Esr, Thunderbird, Enterprise Linux and 4 more 2024-08-02 6.5 Medium
Unexpected data returned from the Safe Browsing API could have led to memory corruption and a potentially exploitable crash. This vulnerability affects Thunderbird < 102.10 and Firefox ESR < 102.10.
CVE-2023-1894 2 Puppet, Redhat 4 Puppet Enterprise, Puppet Server, Satellite and 1 more 2024-08-02 5.3 Medium

CVE-2023-1838 3 Linux, Netapp, Redhat 9 Linux Kernel, H300s, H410c and 6 more 2024-08-02 7.1 High
A use-after-free flaw was found in vhost_net_set_backend in drivers/vhost/net.c in virtio network subcomponent in the Linux kernel due to a double fget. This flaw could allow a local attacker to crash the system, and could even lead to a kernel information leak problem.
CVE-2023-1855 3 Debian, Linux, Redhat 5 Debian Linux, Linux Kernel, Enterprise Linux and 2 more 2024-08-02 6.3 Medium
A use-after-free flaw was found in xgene_hwmon_remove in drivers/hwmon/xgene-hwmon.c in the Hardware Monitoring Linux Kernel Driver (xgene-hwmon). This flaw could allow a local attacker to crash the system due to a race problem. This vulnerability could even lead to a kernel information leak problem.
CVE-2023-1829 2 Linux, Redhat 7 Linux Kernel, Enterprise Linux, Rhel Aus and 4 more 2024-08-02 7.8 High
A use-after-free vulnerability in the Linux Kernel traffic control index filter (tcindex) can be exploited to achieve local privilege escalation. The tcindex_delete function which does not properly deactivate filters in case of a perfect hashes while deleting the underlying structure which can later lead to double freeing the structure. A local attacker user can use this vulnerability to elevate its privileges to root. We recommend upgrading past commit 8c710f75256bb3cf05ac7b1672c82b92c43f3d28.
CVE-2023-1786 3 Canonical, Fedoraproject, Redhat 4 Cloud-init, Ubuntu Linux, Fedora and 1 more 2024-08-02 5.5 Medium
Sensitive data could be exposed in logs of cloud-init before version 23.1.2. An attacker could use this information to find hashed passwords and possibly escalate their privilege.
CVE-2023-1652 2 Linux, Redhat 2 Linux Kernel, Enterprise Linux 2024-08-02 7.1 High
A use-after-free flaw was found in nfsd4_ssc_setup_dul in fs/nfsd/nfs4proc.c in the NFS filesystem in the Linux Kernel. This issue could allow a local attacker to crash the system or it may lead to a kernel information leak problem.
CVE-2023-1729 3 Fedoraproject, Libraw, Redhat 3 Fedora, Libraw, Enterprise Linux 2024-08-02 6.5 Medium
A flaw was found in LibRaw. A heap-buffer-overflow in raw2image_ex() caused by a maliciously crafted file may lead to an application crash.
CVE-2023-1664 1 Redhat 8 Amq Broker, Build Of Quarkus, Jboss A-mq and 5 more 2024-08-02 6.5 Medium
A flaw was found in Keycloak. This flaw depends on a non-default configuration "Revalidate Client Certificate" to be enabled and the reverse proxy is not validating the certificate before Keycloak. Using this method an attacker may choose the certificate which will be validated by the server. If this happens and the KC_SPI_TRUSTSTORE_FILE_FILE variable is missing/misconfigured, any trustfile may be accepted with the logging information of "Cannot validate client certificate trust: Truststore not available". This may not impact availability as the attacker would have no access to the server, but consumer applications Integrity or Confidentiality may be impacted considering a possible access to them. Considering the environment is correctly set to use "Revalidate Client Certificate" this flaw is avoidable.
CVE-2023-1668 3 Cloudbase, Debian, Redhat 8 Open Vswitch, Debian Linux, Enterprise Linux and 5 more 2024-08-02 8.2 High
A flaw was found in openvswitch (OVS). When processing an IP packet with protocol 0, OVS will install the datapath flow without the action modifying the IP header. This issue results (for both kernel and userspace datapath) in installing a datapath flow matching all IP protocols (nw_proto is wildcarded) for this flow, but with an incorrect action, possibly causing incorrect handling of other IP packets with a != 0 IP protocol that matches this dp flow.
CVE-2023-1637 2 Linux, Redhat 7 Linux Kernel, Enterprise Linux, Rhel Aus and 4 more 2024-08-02 5.5 Medium
A flaw that boot CPU could be vulnerable for the speculative execution behavior kind of attacks in the Linux kernel X86 CPU Power management options functionality was found in the way user resuming CPU from suspend-to-RAM. A local user could use this flaw to potentially get unauthorized access to some memory of the CPU similar to the speculative execution behavior kind of attacks.
CVE-2023-1667 4 Debian, Fedoraproject, Libssh and 1 more 5 Debian Linux, Fedora, Libssh and 2 more 2024-08-02 6.5 Medium
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-2023-1582 2 Linux, Redhat 2 Linux Kernel, Enterprise Linux 2024-08-02 4.7 Medium
A race problem was found in fs/proc/task_mmu.c in the memory management sub-component in the Linux kernel. This issue may allow a local attacker with user privilege to cause a denial of service.
CVE-2023-1579 2 Gnu, Redhat 2 Binutils, Enterprise Linux 2024-08-02 7.8 High
Heap based buffer overflow in binutils-gdb/bfd/libbfd.c in bfd_getl64.
CVE-2023-1584 2 Quarkus, Redhat 3 Quarkus, Quarkus, Service Registry 2024-08-02 7.5 High
A flaw was found in Quarkus. Quarkus OIDC can leak both ID and access tokens in the authorization code flow when an insecure HTTP protocol is used, which can allow attackers to access sensitive user data directly from the ID token or by using the access token to access user data from OIDC provider services. Please note that passwords are not stored in access tokens.
CVE-2023-1513 3 Fedoraproject, Linux, Redhat 3 Fedora, Linux Kernel, Enterprise Linux 2024-08-02 3.3 Low
A flaw was found in KVM. When calling the KVM_GET_DEBUGREGS ioctl, on 32-bit systems, there might be some uninitialized portions of the kvm_debugregs structure that could be copied to userspace, causing an information leak.
CVE-2023-1476 2 Linux, Redhat 6 Linux Kernel, Enterprise Linux, Enterprise Linux Eus and 3 more 2024-08-02 7 High
