https://notcve.org/view.php?id=CVE-2024-3049
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. Se encontró una falla en Booth, un administrador de tickets de clúster. Si se pasa un hash especialmente manipulado a gcry_md_get_algo_dlen(), es posible que el servidor Booth acepte un HMAC no válido. • https://github.com/truonghuuphuc/CVE-2024-30491-Poc https://access.redhat.com/errata/RHSA-2024:3657 https://access.redhat.com/errata/RHSA-2024:3658 https://access.redhat.com/errata/RHSA-2024:3659 https://access.redhat.com/errata/RHSA-2024:3660 https://access.redhat.com/errata/RHSA-2024:3661 https://access.redhat.com/errata/RHSA-2024:4400 https://access.redhat.com/errata/RHSA-2024:4411 https://access.redhat.com/security/cve/CVE-2024-3049 https://bugzilla.redhat.com/sho • CWE-345: Insufficient Verification of Data Authenticity •
CVSS: 7.8EPSS: 0%CPEs: 51EXPL: 0CVE-2023-3972 – Insights-client: unsafe handling of temporary files and directories
https://notcve.org/view.php?id=CVE-2023-3972
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).

CVSS: 7.8EPSS: 0%CPEs: 58EXPL: 0CVE-2023-3899 – Subscription-manager: inadequate authorization of com.redhat.rhsm1 d-bus interface allows local users to modify configuration
https://notcve.org/view.php?id=CVE-2023-3899
A vulnerability was found in subscription-manager that allows local privilege escalation due to inadequate authorization. The D-Bus interface com.redhat.RHSM1 exposes a significant number of methods to all users that could change the state of the registration. By using the com.redhat.RHSM1.Config.SetAll() method, a low-privileged local user could tamper with the state of the registration, by unregistering the system or by changing the current entitlements. This flaw allows an attacker to set arbitrary configuration directives for /etc/rhsm/rhsm.conf, which can be abused to cause a local privilege escalation to an unconfined root. • https://access.redhat.com/errata/RHSA-2023:4701 https://access.redhat.com/errata/RHSA-2023:4702 https://access.redhat.com/errata/RHSA-2023:4703 https://access.redhat.com/errata/RHSA-2023:4704 https://access.redhat.com/errata/RHSA-2023:4705 https://access.redhat.com/errata/RHSA-2023:4706 https://access.redhat.com/errata/RHSA-2023:4707 https://access.redhat.com/errata/RHSA-2023:4708 https://access.redhat.com/security/cve/CVE-2023-3899 https://bugzilla.redhat.com/show • CWE-285: Improper Authorization CWE-863: Incorrect Authorization •
CVSS: 7.8EPSS: 0%CPEs: 35EXPL: 0CVE-2023-0494 – X.Org Server DeepCopyPointerClasses Use-After-Free Local Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2023-0494
A vulnerability was found in X.Org. This issue occurs due to a dangling pointer in DeepCopyPointerClasses that can be exploited by ProcXkbSetDeviceInfo() and ProcXkbGetDeviceInfo() to read and write into freed memory. This can lead to local privilege elevation on systems where the X server runs privileged and remote code execution for ssh X forwarding sessions. This vulnerability allows local attackers to escalate privileges on affected installations of X.Org Server. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the DeepCopyPointerClasses function. • https://bugzilla.redhat.com/show_bug.cgi?id=2165995 https://gitlab.freedesktop.org/xorg/xserver/-/commit/0ba6d8c37071131a49790243cdac55392ecf71ec https://lists.x.org/archives/xorg-announce/2023-February/003320.html https://security.gentoo.org/glsa/202305-30 https://access.redhat.com/security/cve/CVE-2023-0494 • CWE-416: Use After Free •
CVSS: 8.6EPSS: 0%CPEs: 12EXPL: 0CVE-2022-2601 – grub2: Buffer overflow in grub_font_construct_glyph() can lead to out-of-bound write and possible secure boot bypass
https://notcve.org/view.php?id=CVE-2022-2601
A buffer overflow was found in grub_font_construct_glyph(). A malicious crafted pf2 font can lead to an overflow when calculating the max_glyph_size value, allocating a smaller than needed buffer for the glyph, this further leads to a buffer overflow and a heap based out-of-bounds write. An attacker may use this vulnerability to circumvent the secure boot mechanism. Se encontró un desbordamiento del búfer en grub_font_construct_glyph(). Una fuente pf2 manipulada maliciosamente puede provocar un desbordamiento al calcular el valor max_glyph_size, asignando un búfer más pequeño de lo necesario para el glifo, lo que además provoca un desbordamiento del búfer y una escritura fuera de los límites basada en el heap. • https://bugzilla.redhat.com/show_bug.cgi?id=2112975#c0 https://security.gentoo.org/glsa/202311-14 https://security.netapp.com/advisory/ntap-20230203-0004 https://access.redhat.com/security/cve/CVE-2022-2601 https://bugzilla.redhat.com/show_bug.cgi?id=2112975 • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •
