CVSS: 7.8EPSS: 41%CPEs: 39EXPL: 1CVE-2023-50868 – bind9: Preparing an NSEC3 closest encloser proof can exhaust CPU resources
https://notcve.org/view.php?id=CVE-2023-50868
13 Feb 2024 — The Closest Encloser Proof aspect of the DNS protocol (in RFC 5155 when RFC 9276 guidance is skipped) allows remote attackers to cause a denial of service (CPU consumption for SHA-1 computations) via DNSSEC responses in a random subdomain attack, aka the "NSEC3" issue. The RFC 5155 specification implies that an algorithm must perform thousands of iterations of a hash function in certain situations.

https://notcve.org/view.php?id=CVE-2024-0229
17 Jan 2024 — 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. Se encontró una falla de acceso a la memoria fuera de los límites en el servidor X.Org.

17 Jan 2024 — A flaw was found in X.Org server. In the XISendDeviceHierarchyEvent function, it is possible to exceed the allocated array length when certain new device IDs are added to the xXIHierarchyInfo struct. This can trigger a heap buffer overflow condition, which may lead to an application crash or remote code execution in SSH X11 forwarding environments. Se encontró una falla en el servidor X.Org.

24 Dec 2023 — sendmail through 8.17.2 allows SMTP smuggling in certain configurations. Remote attackers can use a published exploitation technique to inject e-mail messages with a spoofed MAIL FROM address, allowing bypass of an SPF protection mechanism. This occurs because sendmail supports <LF>.<CR><LF> but some other popular e-mail servers do not. This is resolved in 8.18 and later versions with 'o' in srv_features. sendmail hasta al menos 8.14.7 permite el contrabando SMTP en ciertas configuraciones. • http://www.openwall.com/lists/oss-security/2023/12/24/1 • CWE-345: Insufficient Verification of Data Authenticity •

https://notcve.org/view.php?id=CVE-2023-48795
18 Dec 2023 — The SSH transport protocol with certain OpenSSH extensions, found in OpenSSH before 9.6 and other products, allows remote attackers to bypass integrity checks such that some packets are omitted (from the extension negotiation message), and a client and server may consequently end up with a connection for which some security features have been downgraded or disabled, aka a Terrapin attack. This occurs because the SSH Binary Packet Protocol (BPP), implemented by these extensions, mishandles the handshake phas... • https://packetstorm.news/files/id/176280 • CWE-222: Truncation of Security-relevant Information CWE-354: Improper Validation of Integrity Check Value •

https://notcve.org/view.php?id=CVE-2023-6660
12 Dec 2023 — When a program running on an affected system appends data to a file via an NFS client mount, the bug can cause the NFS client to fail to copy in the data to be written but proceed as though the copy operation had succeeded. This means that the data to be written is instead replaced with whatever data had been in the packet buffer previously. Thus, an unprivileged user with access to an affected system may abuse the bug to trigger disclosure of sensitive information. In particular, the leak is limited to dat... • https://security.freebsd.org/advisories/FreeBSD-SA-23:18.nfsclient.asc •

24 Nov 2023 — OpenZFS through 2.1.13 and 2.2.x through 2.2.1, in certain scenarios involving applications that try to rely on efficient copying of file data, can replace file contents with zero-valued bytes and thus potentially disable security mechanisms. NOTE: this issue is not always security related, but can be security related in realistic situations. A possible example is cp, from a recent GNU Core Utilities (coreutils) version, when attempting to preserve a rule set for denying unauthorized access.

08 Nov 2023 — In versions of FreeBSD 13-RELEASE before 13-RELEASE-p5, under certain circumstances the cap_net libcasper(3) service incorrectly validates that updated constraints are strictly subsets of the active constraints.

This could permit the application to resolve domain names that were previously restricted.
