GnuTLS Security Advisory: Mitigation for Timing Attack Post OpenSSL Fix

Last week, we wrote about a bunch of memory management bugs that were fixed in the latest security update of the popular OpenSSL encryption library. Along with those memory bugs, we also reported on a bug dubbed CVE-2022-4304: Timing Oracle in RSA Decryption . . In this bug, firing the same encrypted message over and over again at a server, but modifying the padding at the end of the data to make the data invalid, and thus provoking some sort of unpredictable behaviour… …wouldn’t take a consistent amount of time, assuming you were close to the target on the network that you could reliably guess how long the data transfer part of the process would take. . GnuTLS has released a patch addressing timing attack vulnerabilities, enhancing memory management and ensuring cryptographic processes run in constant time..

Ubuntu: CVE-2021-3939 Severe Vulnerability in AccountsService Memory Issue

A local privilege escalation security vulnerability (CVE-2021-3939) could allow attackers to gain root access on Ubuntu systems by exploiting a double-free memory corruption bug in GNOME's AccountsService component. . AccountsService is a D-Bus service that helps manipulate and query information attached to the user accounts available on a device. The security flaw (a memory management bug tracked as CVE-2021-3939 ) was accidentally spotted by GitHub security researcher Kevin Backhouse while testing an exploit demo for another AccountsService bug that also made it possible to escalate privileges to root on vulnerable devices. . A vulnerability in Ubuntu's AccountsService presents potential root access threats, enabling privilege elevation through memory corruption mechanisms..

Red Hat Critical Advisory: Immediate Action Required For File Transfer Bug

On the surface, it was just another turn of the endless cycle of software release, hole discovery, and patching: operating system vendor Red Hat issued an advisory Tuesday warning the world about a serious security hole in a file transfer program . . . . On the surface, it was just another turn of the endless cycle of software release, hole discovery, and patching: operating system vendor Red Hat issued an advisory Tuesday warning the world about a serious security hole in a file transfer program that comes with Linux, and urged customers to download a patch. There was just one problem: Red Hat's advisory jumped the gun on what was intended to be a simultaneous multi-vendor release, carefully coordinated by the government-funded Computer Emergency Response Team (CERT), and scheduled for December 3rd. Caught off guard, other Linux vendors were rushing Wednesday to finalize their own patches for the hole-- a memory-allocation bug in the ubiquitous Washington University WU-FTPd program.

OpenSSH is a 100% complete SSH protocol version 1.3, 1.5 and 2.0 implementation and includes sftp client and server support. We would like to thank the OpenSSH community for their continued support and encouragement. Important Changes: ================== A security hole that may allow an attacker to authenticate if -- and only if -- the administrator has enabled KerberosV. By default, OpenSSH KerberosV support only becomes active after KerberosV has been properly configured. An excessive memory clearing bug (which we believe to be unexploitable) also exists, but since this may cause daemon crashes, we are providing a fix as well. Various other non-critical fixes (~& support and more). OpenSSH is brought to you by Markus Friedl, Niels Provos, Theo de Raadt, Kevin Steves, Damien Miller and Ben Lindstrom. . OpenSSH 3.0.1 resolves vulnerabilities related to SSH key authentication flaws and a memory leak, delivering crucial updates.. OpenSSH Release, Authentication Threat, Security Update. .
