CVE-2026-45787 electerm's encrypt method not safe enough

electerm is an open-sourced terminal/ssh/sftp/telnet/serialport/RDP/VNC/Spice/ftp client. Prior to 3.9.5, deterministic AES-192-CBC with a fixed zero IV, constant KDF salt, and no MAC leads to confidentiality and integrity failures for synced bookmark/profile data. Attackers can crack common...

aiosend: Deserialization of request body before signature verification (Pre-auth DoS) in webhook handler

Vulnerability Description In aiosend/webhook/base.py, the WebhookHandler.feedupdate method performs full deserialization of the incoming JSON via Pydantic before verifying the HMAC signature. Anyone can send a request with an arbitrary body — the server will parse it, spend CPU and memory, and on...

Astra Linux - уязвимость в linux-5.10

In the Linux kernel, the following vulnerability has been resolved: ksmbd: MAC comparisons need to be performed in constant time. To prevent timing attacks, MAC comparisons must be done in constant time. Replace the memcmp function with the correct function, cryptomemneq...

Astra Linux - уязвимость в linux-5.10, linux-5.15, linux-6.1

In the Linux kernel, the following vulnerability has been resolved: SCTP: The comparison of MACs has been fixed to require constant-time operations. To prevent timing attacks, MACs need to be compared in constant-time. Use the appropriate helper functions for this purpose...

Astra Linux - уязвимость в linux-5.10

In the Linux kernel, the following vulnerability has been resolved: net/tcp-ao: The comparison of MACs is now performed at constant time. To prevent timing attacks, MACs need to be compared at constant time. Use the appropriate helper functions for this purpose...

CVE-2026-8836

A vulnerability was found in lwIP up to 2.2.1. Affected is the function snmpparseinboundframe of the file src/apps/snmp/snmpmsg.c of the component snmpv3 USM Handler. Performing a manipulation of the argument msgAuthenticationParameters results in stack-based buffer overflow. The attack may be...

GHSA-G29V-Q6H7-76WH electerm's encrypt method not safe enough

Impact Insecure sync encryption: deterministic AES-192-CBC with a fixed zero IV, constant KDF salt, and no MAC leads to confidentiality and integrity failures for synced bookmark/profile data. Attackers can crack common passwords across installs and perform undetected ciphertext bit-flips to alte...

EUVD-2026-29086

Deserialization of untrusted data CWE-502 in pgAdmin 4 FileBackedSessionManager. The session manager performed unsafe deserialization of session-file contents using Python's standard object-serialization module before performing any HMAC integrity check. Any file dropped into the sessions directo...

CVE-2026-43384

A flaw was found in the Linux kernel's TCP Authentication Option TCP-AO implementation. This vulnerability arises from a non-constant-time comparison of Message Authentication Codes MACs. A remote attacker could potentially exploit this timing discrepancy to perform a timing attack, which may lea...

CVE-2026-43383

A flaw was found in the Linux kernel's TCP MD5 signature option. This vulnerability allows a remote attacker to perform timing attacks due to a non-constant-time comparison of Message Authentication Codes MACs. By observing the time taken for MAC comparisons, an attacker could potentially infer...

EUVD-2026-28689

In the Linux kernel, the following vulnerability has been resolved: net/tcp-md5: Fix MAC comparison to be constant-time To prevent timing attacks, MACs need to be compared in constant time. Use the appropriate helper function for this...
