This vulnerability exists when a rewrite directive uses a regex pattern with distinct, overlapping Perl-Compatible Regular Expression (PCRE) captures (for example, ^/((.*))$) and a… | ||
| CVE-2026-0966 | Hig | 0.53 | 8.2 | 0.01 | Mar 26, 2026 | A flaw was found in libssh. The API function `ssh_get_hexa()` is vulnerable to a denial of service when processing zero-length input. This can be exploited remotely by an attacker during GSSAPI (Generic Security Service Application Program Interface) authentication if the… | ||
| CVE-2024-3183 | Hig | 0.53 | 8.1 | 0.02 | Jun 12, 2024 | 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… | ||
| CVE-2023-39191 | Hig | 0.53 | 8.2 | 0.01 | Oct 4, 2023 | An improper input validation flaw was found in the eBPF subsystem in the Linux kernel. The issue occurs due to a lack of proper validation of dynamic pointers within user-supplied eBPF programs prior to executing them. This may allow an attacker with CAP_BPF privileges to… | ||
| CVE-2023-32258 | Hig | 0.53 | 8.1 | 0.03 | Jul 24, 2023 | A flaw was found in the Linux kernel's ksmbd, a high-performance in-kernel SMB server. The specific flaw exists within the processing of SMB2_LOGOFF and SMB2_CLOSE commands. The issue results from the lack of proper locking when performing operations on an object. An attacker… | ||
| CVE-2023-32257 | Hig | 0.53 | 8.1 | 0.02 | Jul 24, 2023 | A flaw was found in the Linux kernel's ksmbd, a high-performance in-kernel SMB server. The specific flaw exists within the processing of SMB2_SESSION_SETUP and SMB2_LOGOFF commands. The issue results from the lack of proper locking when performing operations on an object. An… | ||
| CVE-2022-1665 | Hig | 0.53 | 8.2 | 0.00 | Jun 21, 2022 | A set of pre-production kernel packages of Red Hat Enterprise Linux for IBM Power architecture can be booted by the grub in Secure Boot mode even though it shouldn't. These kernel builds don't have the secure boot lockdown patches applied to it and can bypass the secure boot… | ||
| CVE-2021-3750 | Hig | 0.53 | 8.2 | 0.01 | May 2, 2022 | A DMA reentrancy issue was found in the USB EHCI controller emulation of QEMU. EHCI does not verify if the Buffer Pointer overlaps with its MMIO region when it transfers the USB packets. Crafted content may be written to the controller's registers and trigger undesirable actions… | ||
| CVE-2021-4207 | Hig | 0.53 | 8.2 | 0.00 | Apr 29, 2022 | A flaw was found in the QXL display device emulation in QEMU. A double fetch of guest controlled values `cursor->header.width` and `cursor->header.height` can lead to the allocation of a small cursor object followed by a subsequent heap-based buffer overflow. A malicious… | ||
| CVE-2021-4206 | Hig | 0.53 | 8.2 | 0.01 | Apr 29, 2022 | A flaw was found in the QXL display device emulation in QEMU. An integer overflow in the cursor_alloc() function can lead to the allocation of a small cursor object followed by a subsequent heap-based buffer overflow. This flaw allows a malicious privileged guest user to crash… | ||
| CVE-2020-25717 | Hig | 0.53 | 8.1 | 0.02 | Feb 18, 2022 | A flaw was found in the way Samba maps domain users to local users. An authenticated attacker could use this flaw to cause possible privilege escalation. | ||
| CVE-2021-3935 | Hig | 0.53 | 8.1 | 0.01 | Nov 22, 2021 | When PgBouncer is configured to use "cert" authentication, a man-in-the-middle attacker can inject arbitrary SQL queries when a connection is first established, despite the use of TLS certificate verification and encryption. This flaw affects PgBouncer versions prior to 1.16.1. | ||
| CVE-2021-20305 | Hig | 0.53 | 8.1 | 0.02 | Apr 5, 2021 | A flaw was found in Nettle in versions before 3.7.2, where several Nettle signature verification functions (GOST DSA, EDDSA & ECDSA) result in the Elliptic Curve Cryptography point (ECC) multiply function being called with out-of-range scalers, possibly resulting in incorrect… | ||
| CVE-2021-20233 | Hig | 0.53 | 8.2 | 0.01 | Mar 3, 2021 | A flaw was found in grub2 in versions prior to 2.06. Setparam_prefix() in the menu rendering code performs a length calculation on the assumption that expressing a quoted single quote will require 3 characters, while it actually requires 4 characters which allows an attacker to… | ||
| CVE-2020-25632 | Hig | 0.53 | 8.2 | 0.01 | Mar 3, 2021 | A flaw was found in grub2 in versions prior to 2.06. The rmmod implementation allows the unloading of a module used as a dependency without checking if any other dependent module is still loaded leading to a use-after-free scenario. This could allow arbitrary code to be executed… | ||
| CVE-2020-2604 | Hig | 0.53 | 8.1 | 0.05 | Jan 15, 2020 | Vulnerability in the Java SE, Java SE Embedded product of Oracle Java SE (component: Serialization).
