The Ubuntu security team has recently discovered and addressed multiple vulnerabilities in the Apache HTTP Server. The vulnerabilities affected several versions of Ubuntu and could potentially lead to server disruption and injection of malicious code...
The Linux kernel since last year has mistakenly left systems relying on the original Indirect Branch Restricted Speculation (IBRS) for Spectre V2 mitigation without Single Threaded Indirect Branch Predictor (STIBP) coverage for cross-HyperThread dealing with this Spectre vulnerability. There is a patch underway that is resolving this issue for Intel Skylake era systems.
I discovered a logic bug in the readline dependency partially reveals file information when parsing the file specified in the INPUTRC environment variable. This could allow attackers to move laterally on a box where sshd is running, a given user is able to login, and the user’s private key is stored in a known location (/home/user/.ssh/id_rsa).
CVE-2022-27672 is being made public today as the "Cross-Thread Return Address Predictions" bug affecting various AMD and Hygon processors. This vulnerability affects the SMT mode where one sibling thread transitions out of the C0 state and the other sibling thread could use return target predictions.
A proposed Linux kernel patch would provide a new Kconfig build time option of "CONFIG_DEFAULT_CPU_MITIGATIONS_OFF" to build an insecure kernel if wanting to avoid the growing list of CPU security mitigations within the kernel and their associated performance overhead.
Sudo is one of the most essential, powerful, and often used tools that comes as a core command pre-installed on macOS and practically every other UNIX or Linux-based operating system. It is also one of the programs that comes pre-installed as a core command.
A new privilege escalation vulnerability has been identified in the Linux kernel by researcher Davide Ornaghi. This vulnerability might enable a local attacker to execute code on vulnerable computers with elevated rights if the kernel is installed on those systems.
The Zero Day Initiative (ZDI), a zero-day security research firm, announced a new Linux kernel security bug. This hole allows authenticated remote users to disclose sensitive information and run code on vulnerable Linux kernel versions.
Malicious actors are actively attempting to exploit a recently patched critical vulnerability in Control Web Panel (CWP) that enables elevated privileges and unauthenticated remote code execution (RCE) on susceptible servers.
Canonical has published new kernel security updates for all of its supported Ubuntu Linux releases as a massive update that addresses more than 20 security vulnerabilities discovered by various researchers in the upstream kernels.
Thirty security vulnerabilities in numerous outdated WordPress plugins and themes are being leveraged by a novel Linux malware to facilitate malicious JavaScript injections, reports BleepingComputer.
Merry Christmas, Linux systems administrators: Here's a kernel vulnerability with a CVSS score of 10 in your SMB server for the holiday season giving an unauthenticated user remote code execution.
The patch management process can be painful, tedious, and time and labor intensive. Often, all this effort is for no other purpose than to maintain the operational status quo. And for devs or sysadmins, patch management has to happen on top of handling every-day activities as well as any other additional challenges that occur during service interruptions or system reboots.
