CVE-2024-0564 2 Linux, Redhat 2 Linux Kernel, Enterprise Linux 2024-11-25 N/A 5.3 MEDIUM
A flaw was found in the Linux kernel's memory deduplication mechanism. The max page sharing of Kernel Samepage Merging (KSM), added in Linux kernel version 4.4.0-96.119, can create a side channel. When the attacker and the victim share the same host and the default setting of KSM is "max page sharing=256", it is possible for the attacker to time the unmap to merge with the victim's page. The unmapping time depends on whether it merges with the victim's page and additional physical pages are created beyond the KSM's "max page share". Through these operations, the attacker can leak the victim's page.
CVE-2024-2698 2 Freeipa, Redhat 3 Freeipa, Enterprise Linux, Enterprise Linux Eus 2024-11-24 N/A 8.8 HIGH
A vulnerability was found in FreeIPA in how the initial implementation of MS-SFU by MIT Kerberos was missing a condition for granting the "forwardable" flag on S4U2Self tickets. Fixing this mistake required adding a special case for the check_allowed_to_delegate() function: If the target service argument is NULL, then it means the KDC is probing for general constrained delegation rules and not checking a specific S4U2Proxy request. In FreeIPA 4.11.0, the behavior of ipadb_match_acl() was modified to match the changes from upstream MIT Kerberos 1.20. However, a mistake resulting in this mechanism applies in cases where the target service argument is set AND where it is unset. This results in S4U2Proxy requests being accepted regardless of whether or not there is a matching service delegation rule.
CVE-2024-0229 3 Fedoraproject, Redhat, X.org 8 Fedora, Enterprise Linux, Enterprise Linux Aus and 5 more 2024-11-23 N/A 7.8 HIGH
An out-of-bounds memory access flaw was found in the X.Org server. This issue can be triggered when a device frozen by a sync grab is reattached to a different master device. This issue may lead to an application crash, local privilege escalation (if the server runs with extended privileges), or remote code execution in SSH X11 forwarding environments.
CVE-2024-8354 2 Qemu, Redhat 2 Qemu, Enterprise Linux 2024-11-21 N/A 5.5 MEDIUM
A flaw was found in QEMU. An assertion failure was present in the usb_ep_get() function in hw/net/core.c when trying to get the USB endpoint from a USB device. This flaw may allow a malicious unprivileged guest user to crash the QEMU process on the host and cause a denial of service condition.
CVE-2024-8235 1 Redhat 2 Enterprise Linux, Libvirt 2024-11-21 N/A 6.2 MEDIUM
A flaw was found in libvirt. A refactor of the code fetching the list of interfaces for multiple APIs introduced a corner case on platforms where allocating 0 bytes of memory results in a NULL pointer. This corner case would lead to a NULL-pointer dereference and subsequent crash of virtinterfaced. This issue could allow clients connecting to the read-only socket to crash the virtinterfaced daemon.
CVE-2024-7006 2 Libtiff, Redhat 5 Libtiff, Enterprise Linux, Enterprise Linux For Arm 64 and 2 more 2024-11-21 N/A 7.5 HIGH
A null pointer dereference flaw was found in Libtiff via `tif_dirinfo.c`. This issue may allow an attacker to trigger memory allocation failures through certain means, such as restricting the heap space size or injecting faults, causing a segmentation fault. This can cause an application crash, eventually leading to a denial of service.
CVE-2024-6505 2 Qemu, Redhat 2 Qemu, Enterprise Linux 2024-11-21 N/A 6.8 MEDIUM
A flaw was found in the virtio-net device in QEMU. When enabling the RSS feature on the virtio-net network card, the indirections_table data within RSS becomes controllable. Setting excessively large values may cause an index out-of-bounds issue, potentially resulting in heap overflow access. This flaw allows a privileged user in the guest to crash the QEMU process on the host.
CVE-2024-6239 2 Freedesktop, Redhat 2 Poppler, Enterprise Linux 2024-11-21 N/A 7.5 HIGH
A flaw was found in the Poppler's Pdfinfo utility. This issue occurs when using -dests parameter with pdfinfo utility. By using certain malformed input files, an attacker could cause the utility to crash, leading to a denial of service.
CVE-2024-6237 1 Redhat 3 389 Directory Server, Directory Server, Enterprise Linux 2024-11-21 N/A 6.5 MEDIUM
A flaw was found in the 389 Directory Server. This flaw allows an unauthenticated user to cause a systematic server crash while sending a specific extended search request, leading to a denial of service.
CVE-2024-5742 2 Gnu, Redhat 2 Nano, Enterprise Linux 2024-11-21 N/A 6.7 MEDIUM
A vulnerability was found in GNU Nano that allows a possible privilege escalation through an insecure temporary file. If Nano is killed while editing, a file it saves to an emergency file with the permissions of the running user provides a window of opportunity for attackers to escalate privileges through a malicious symlink.
CVE-2024-4629 1 Redhat 8 Build Of Keycloak, Enterprise Linux, Keycloak and 5 more 2024-11-21 N/A 6.5 MEDIUM
A vulnerability was found in Keycloak. This flaw allows attackers to bypass brute force protection by exploiting the timing of login attempts. By initiating multiple login requests simultaneously, attackers can exceed the configured limits for failed attempts before the system locks them out. This timing loophole enables attackers to make more guesses at passwords than intended, potentially compromising account security on affected systems.
CVE-2024-3567 2 Qemu, Redhat 2 Qemu, Enterprise Linux 2024-11-21 N/A 5.5 MEDIUM
A flaw was found in QEMU. An assertion failure was present in the update_sctp_checksum() function in hw/net/net_tx_pkt.c when trying to calculate the checksum of a short-sized fragmented packet. This flaw allows a malicious guest to crash QEMU and cause a denial of service condition.
CVE-2024-3183 1 Redhat 5 Enterprise Linux, Enterprise Linux Aus, Enterprise Linux Eus and 2 more 2024-11-21 N/A 8.1 HIGH
A vulnerability was found in FreeIPA in a way when a Kerberos TGS-REQ is encrypted using the client’s session key. This key is different for each new session, which protects it from brute force attacks. However, the ticket it contains is encrypted using the target principal key directly. For user principals, this key is a hash of a public per-principal randomly-generated salt and the user’s password. If a principal is compromised it means the attacker would be able to retrieve tickets encrypted to any principal, all of them being encrypted by their own key directly. By taking these tickets and salts offline, the attacker could run brute force attacks to find character strings able to decrypt tickets when combined to a principal salt (i.e. find the principal’s password).
CVE-2024-3049 2 Clusterlabs, Redhat 8 Booth, Enterprise Linux, Enterprise Linux Eus and 5 more 2024-11-21 N/A 5.9 MEDIUM
A flaw was found in Booth, a cluster ticket manager. If a specially-crafted hash is passed to gcry_md_get_algo_dlen(), it may allow an invalid HMAC to be accepted by the Booth server.
CVE-2024-23301 4 Fedoraproject, Redhat, Relax-and-recover and 1 more 4 Fedora, Enterprise Linux, Relax-and-recover and 1 more 2024-11-21 N/A 5.5 MEDIUM
Relax-and-Recover (aka ReaR) through 2.7 creates a world-readable initrd when using GRUB_RESCUE=y. This allows local attackers to gain access to system secrets otherwise only readable by root.
CVE-2024-1454 3 Fedoraproject, Opensc Project, Redhat 3 Fedora, Opensc, Enterprise Linux 2024-11-21 N/A 3.4 LOW
The use-after-free vulnerability was found in the AuthentIC driver in OpenSC packages, occuring in the card enrolment process using pkcs15-init when a user or administrator enrols or modifies cards. An attacker must have physical access to the computer system and requires a crafted USB device or smart card to present the system with specially crafted responses to the APDUs, which are considered high complexity and low severity. This manipulation can allow for compromised card management operations during enrolment.
CVE-2024-1151 4 Debian, Fedoraproject, Linux and 1 more 4 Debian Linux, Fedora, Linux Kernel and 1 more 2024-11-21 N/A 5.5 MEDIUM
A vulnerability was reported in the Open vSwitch sub-component in the Linux Kernel. The flaw occurs when a recursive operation of code push recursively calls into the code block. The OVS module does not validate the stack depth, pushing too many frames and causing a stack overflow. As a result, this can lead to a crash or other related issues.
CVE-2024-1048 3 Fedoraproject, Gnu, Redhat 3 Fedora, Grub2, Enterprise Linux 2024-11-21 N/A 3.3 LOW
A flaw was found in the grub2-set-bootflag utility of grub2. After the fix of CVE-2019-14865, grub2-set-bootflag will create a temporary file with the new grubenv content and rename it to the original grubenv file. If the program is killed before the rename operation, the temporary file will not be removed and may fill the filesystem when invoked multiple times, resulting in a filesystem out of free inodes or blocks.
CVE-2024-0914 2 Opencryptoki Project, Redhat 2 Opencryptoki, Enterprise Linux 2024-11-21 N/A 5.9 MEDIUM
A timing side-channel vulnerability has been discovered in the opencryptoki package while processing RSA PKCS#1 v1.5 padded ciphertexts. This flaw could potentially enable unauthorized RSA ciphertext decryption or signing, even without access to the corresponding private key.
CVE-2024-0841 2 Linux, Redhat 2 Linux Kernel, Enterprise Linux 2024-11-21 N/A 6.6 MEDIUM
A null pointer dereference flaw was found in the hugetlbfs_fill_super function in the Linux kernel hugetlbfs (HugeTLB pages) functionality. This issue may allow a local user to crash the system or potentially escalate their privileges on the system.
