|---|---|---|---|---|---|
| CVE-2020-1730 | 6 Canonical, Fedoraproject, Libssh and 3 more | 6 Ubuntu Linux, Fedora, Libssh and 3 more | 2023-11-07 | 5.0 MEDIUM | 5.3 MEDIUM |
| A flaw was found in libssh versions before 0.8.9 and before 0.9.4 in the way it handled AES-CTR (or DES ciphers if enabled) ciphers. The server or client could crash when the connection hasn't been fully initialized and the system tries to cleanup the ciphers when closing the connection. The biggest threat from this vulnerability is system availability. | |||||
| CVE-2020-1967 | 10 Broadcom, Debian, Fedoraproject and 7 more | 26 Fabric Operating System, Debian Linux, Fedora and 23 more | 2023-11-07 | 5.0 MEDIUM | 7.5 HIGH |
| Server or client applications that call the SSL_check_chain() function during or after a TLS 1.3 handshake may crash due to a NULL pointer dereference as a result of incorrect handling of the "signature_algorithms_cert" TLS extension. The crash occurs if an invalid or unrecognised signature algorithm is received from the peer. This could be exploited by a malicious peer in a Denial of Service attack. OpenSSL version 1.1.1d, 1.1.1e, and 1.1.1f are affected by this issue. This issue did not affect OpenSSL versions prior to 1.1.1d. Fixed in OpenSSL 1.1.1g (Affected 1.1.1d-1.1.1f). | |||||

| CVE-2020-10711 | 5 Canonical, Debian, Linux and 2 more | 11 Ubuntu Linux, Debian Linux, Linux Kernel and 8 more | 2023-11-07 | 4.3 MEDIUM | 5.9 MEDIUM |
| A NULL pointer dereference flaw was found in the Linux kernel's SELinux subsystem in versions before 5.7. This flaw occurs while importing the Commercial IP Security Option (CIPSO) protocol's category bitmap into the SELinux extensible bitmap via the' ebitmap_netlbl_import' routine. While processing the CIPSO restricted bitmap tag in the 'cipso_v4_parsetag_rbm' routine, it sets the security attribute to indicate that the category bitmap is present, even if it has not been allocated. This issue leads to a NULL pointer dereference issue while importing the same category bitmap into SELinux. This flaw allows a remote network user to crash the system kernel, resulting in a denial of service. | |||||
| CVE-2020-10730 | 5 Debian, Fedoraproject, Opensuse and 2 more | 5 Debian Linux, Fedora, Leap and 2 more | 2023-11-07 | 4.0 MEDIUM | 6.5 MEDIUM |
| A NULL pointer dereference, or possible use-after-free flaw was found in Samba AD LDAP server in versions before 4.10.17, before 4.11.11 and before 4.12.4. Although some versions of Samba shipped with Red Hat Enterprise Linux do not support Samba in AD mode, the affected code is shipped with the libldb package. This flaw allows an authenticated user to possibly trigger a use-after-free or NULL pointer dereference. The highest threat from this vulnerability is to system availability. | |||||
