| CVE-2023-3966 | Hig | 0.49 | 7.5 | 0.01 | Feb 22, 2024 | A flaw was found in Open vSwitch where multiple versions are vulnerable to crafted Geneve packets, which may result in a denial of service and invalid memory accesses. Triggering this issue requires that hardware offloading via the netlink path is enabled. | ||
| CVE-2023-50782 | Hig | 0.49 | 7.5 | 0.01 | Feb 5, 2024 | A flaw was found in the python-cryptography package. This issue may allow a remote attacker to decrypt captured messages in TLS servers that use RSA key exchanges, which may lead to exposure of confidential or sensitive data. | ||
| CVE-2023-50781 | Hig | 0.49 | 7.5 | 0.01 | Feb 5, 2024 | A flaw was found in m2crypto. This issue may allow a remote attacker to decrypt captured messages in TLS servers that use RSA key exchanges, which may lead to exposure of confidential or sensitive data. | ||
| CVE-2024-0553 | Hig | 0.49 | 7.5 | 0.02 | Jan 16, 2024 | A vulnerability was found in GnuTLS. The response times to malformed ciphertexts in RSA-PSK ClientKeyExchange differ from the response times of ciphertexts with correct PKCS#1 v1.5 padding. This issue may allow a remote attacker to perform a timing side-channel attack in the… | ||
| CVE-2023-39198 | Hig | 0.49 | 7.5 | 0.00 | Nov 9, 2023 | A race condition was found in the QXL driver in the Linux kernel. The qxl_mode_dumb_create() function dereferences the qobj returned by the qxl_gem_object_create_with_handle(), but the handle is the only one holding a reference to it. This flaw allows an attacker to guess the… | ||
| CVE-2023-4154 | Hig | 0.49 | 7.5 | 0.01 | Nov 7, 2023 | A design flaw was found in Samba's DirSync control implementation, which exposes passwords and secrets in Active Directory to privileged users and Read-Only Domain Controllers (RODCs). This flaw allows RODCs and users possessing the GET_CHANGES right to access all attributes,… | ||
| CVE-2023-5824 | Hig | 0.49 | 7.5 | 0.05 | Nov 3, 2023 | A flaw was found in Squid. The limits applied for validation of HTTP response headers are applied before caching. However, Squid may grow a cached HTTP response header beyond the configured maximum size, causing a stall or crash of the worker process when a large header is… | ||
| CVE-2023-4692 | Hig | 0.49 | 7.5 | 0.01 | Oct 25, 2023 | An out-of-bounds write flaw was found in grub2's NTFS filesystem driver.
