https://notcve.org/view.php?id=CVE-2025-26595
25 Feb 2025 — A buffer overflow flaw was found in X.Org and Xwayland. The code in XkbVModMaskText() allocates a fixed-sized buffer on the stack and copies the names of the virtual modifiers to that buffer. The code fails to check the bounds of the buffer and would copy the data regardless of the size. 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 t... • https://access.redhat.com/security/cve/CVE-2025-26595 • CWE-121: Stack-based Buffer Overflow •

https://notcve.org/view.php?id=CVE-2025-26594
25 Feb 2025 — A use-after-free flaw was found in X.Org and Xwayland. The root cursor is referenced in the X server as a global variable. If a client frees the root cursor, the internal reference points to freed memory and causes a use-after-free. 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.

https://notcve.org/view.php?id=CVE-2025-26465
18 Feb 2025 — A vulnerability was found in OpenSSH when the VerifyHostKeyDNS option is enabled. A machine-in-the-middle attack can be performed by a malicious machine impersonating a legit server. This issue occurs due to how OpenSSH mishandles error codes in specific conditions when verifying the host key. For an attack to be considered successful, the attacker needs to manage to exhaust the client's memory resource first, turning the attack complexity high. ssh(1) contains a logic error that allows an on-path attacker ... • https://github.com/rxerium/CVE-2025-26465 • CWE-390: Detection of Error Condition Without Action •

https://notcve.org/view.php?id=CVE-2025-26466
18 Feb 2025 — A flaw was found in the OpenSSH package. For each ping packet the SSH server receives, a pong packet is allocated in a memory buffer and stored in a queue of packages. It is only freed when the server/client key exchange has finished. A malicious client may keep sending such packages, leading to an uncontrolled increase in memory consumption on the server side. Consequently, the server may become unavailable, resulting in a denial of service attack. ssh(1) contains a logic error that allows an on-path attac... • https://github.com/rxerium/CVE-2025-26466 • CWE-400: Uncontrolled Resource Consumption CWE-770: Allocation of Resources Without Limits or Throttling •

https://notcve.org/view.php?id=CVE-2024-12243
10 Feb 2025 — A flaw was found in GnuTLS, which relies on libtasn1 for ASN.1 data processing. Due to an inefficient algorithm in libtasn1, decoding certain DER-encoded certificate data can take excessive time, leading to increased resource consumption. This flaw allows a remote attacker to send a specially crafted certificate, causing GnuTLS to become unresponsive or slow, resulting in a denial-of-service condition. Bing Shi discovered that GnuTLS incorrectly handled decoding certain DER-encoded certificates.

10 Feb 2025 — A flaw in libtasn1 causes inefficient handling of specific certificate data. When processing a large number of elements in a certificate, libtasn1 takes much longer than expected, which can slow down or even crash the system. This flaw allows an attacker to send a specially crafted certificate, causing a denial of service attack. USN-7275-1 fixed vulnerabilities in Libtasn1.
