Summary Multiple vulnerabilities were addressed in IBM Aspera HTTP Gateway version 2.3.4 Vulnerability Details CVEID:CVE-2026-2303 DESCRIPTION: The mongo-go-driver repository contains CGo bindings for GSSAPI Kerberos authentication on Linux and macOS. The C wrapper implementation contains a heap...

CVE-2026-68930

Russh is a Rust SSH client & server library. Prior to 0.62.5, russh dispatches channel-scoped Handler callbacks for recipient channel IDs that were never opened or confirmed in russh/src/server/encrypted.rs, serverreadauthenticated, and the execrequest callback. Version 0.62.5 fixes the issue...

July Linux Patch Wednesday. A total of 2,017 vulnerabilities were addressed 539 in the Linux kernel and 504 in Chromium. For comparison, there were 1,888 vulnerabilities in June. Once again, a new record. Moreover, next month will most likely set another record, as 1,704 vulnerabilities have...

libssh2: libssh2: Arbitrary code execution via heap buffer overflow during SSH negotiation

A flaw was found in libssh2. A malicious SSH server can exploit a pre-authentication heap buffer overflow vulnerability by sending a specially crafted packet during the Encrypt-then-MAC ETM cipher negotiation. This allows the server to corrupt heap memory, potentially leading to arbitrary code...

libssh2: libssh2: Arbitrary code execution via double-free in SFTP session

A flaw was found in libssh2. A malicious SSH Secure Shell server can exploit a double-free vulnerability in the sftpopen function. This flaw allows the server to corrupt the heap memory of an authenticated client when it opens an SFTP SSH File Transfer Protocol session. This heap corruption can...

CVE-2026-66035 libssh2 Heap Buffer Overflow via ETM Cipher Negotiation

libssh2 through 1.11.1, fixed in commit 42e33d8, contains a pre-authentication heap buffer overflow vulnerability that allows a malicious SSH server to corrupt heap metadata in any connecting client by sending a packet with a packetlength smaller than the cipher's block size during Encrypt-then-M...

EUVD-2026-48720

libssh2 through 1.11.1, fixed in commit a2ed82d, contains a pre-authentication integer underflow vulnerability in the ssh2ciphercrypt function in src/openssl.c that allows a malicious SSH server to crash any connecting client by negotiating AES-GCM ciphers during handshake. Attackers can exploit...

[SECURITY] Fedora 44 Update: libssh-0.12.1-1.fc44

The ssh library was designed to be used by programmers needing a working SSH implementation by the mean of a library. The complete control of the client is made by the programmer. With libssh, you can remotely execute programs, trans fer files, use a secure and transparent tunnel for your remote...
