Debian Linux Security Advisory 5478-1 - Several vulnerabilities have been discovered in the OpenJDK Java runtime, which may result in bypass of sandbox restrictions, information disclosure, reduced cryptographic strength of the AES implementation, directory traversal or denial of service.

A new, financially motivated operation dubbed LABRAT has been observed weaponizing a now-patched critical flaw in GitLab as part of a cryptojacking and proxyjacking campaign. "The attacker utilized undetected signature-based tools, sophisticated and stealthy cross-platform malware, command-and-control (C2) tools which bypassed firewalls, and kernel-based rootkits to hide their presence," Sysdig

A use-after-free flaw was found in btrfs_get_dev_args_from_path in fs/btrfs/volumes.c in btrfs file-system in the Linux Kernel. This flaw allows a local attacker with special privileges to cause a system crash or leak internal kernel information

A lot of system administrators within the Department of Defense already use the Advanced Intrusion Detection Environment (AIDE). This is mainly because of a Security Technical Implementation Guide (STIG) that states that a file integrity checker must be configured to verify extended file attributes. There are a lot of features to AIDE, and the combination of using AIDE with Red Hat Ansible Automation Platform gives you the ability to automate important corrections to your system configuration. Telling AIDE what to check AIDE can be configured to check multiple file and folder attributes.

A vulnerability in the filesystem image parser for Hierarchical File System Plus (HFS+) of ClamAV could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to an incorrect check for completion when a file is decompressed, which may result in a loop condition that could cause the affected software to stop responding. An attacker could exploit this vulnerability by submitting a crafted HFS+ filesystem image to be scanned by ClamAV on an affected device. A successful exploit could allow the attacker to cause the ClamAV scanning process to stop responding, resulting in a DoS condition on the affected software and consuming available system resources. For a description of this vulnerability, see the ClamAV blog .

IBM Security Guardium 10.6, 11.3, 11.4, and 11.5 could allow a remote authenticated attacker to execute arbitrary commands on the system by sending a specially crafted request. IBM X-Force ID: 258824.

A vulnerability in the CLI of Cisco ThousandEyes Enterprise Agent, Virtual Appliance installation type, could allow an authenticated, local attacker to elevate privileges to root on an affected device. This vulnerability is due to insufficient input validation of user-supplied CLI arguments. An attacker could exploit this vulnerability by authenticating to an affected device and using crafted commands at the prompt. A successful exploit could allow the attacker to execute arbitrary commands as root. The attacker must have valid credentials on the affected device.

A vulnerability in the CLI of Cisco ThousandEyes Enterprise Agent, Virtual Appliance installation type, could allow an authenticated, local attacker to elevate privileges on an affected device. This vulnerability is due to insufficient input validation by the operating system CLI. An attacker could exploit this vulnerability by issuing certain commands using sudo. A successful exploit could allow the attacker to view arbitrary files as root on the underlying operating system. The attacker must have valid credentials on the affected device.

A vulnerability, which was classified as critical, was found in MicroWorld eScan Anti-Virus 7.0.32 on Linux. This affects an unknown part of the file runasroot. The manipulation leads to incorrect execution-assigned permissions. The attack needs to be approached locally. The exploit has been disclosed to the public and may be used. The associated identifier of this vulnerability is VDB-237315. NOTE: The vendor was contacted early about this disclosure but did not respond in any way.

A use-after-free flaw was found in vmxnet3_rq_alloc_rx_buf in drivers/net/vmxnet3/vmxnet3_drv.c in VMware's vmxnet3 ethernet NIC driver in the Linux Kernel. This issue could allow a local attacker to crash the system due to a double-free while cleaning up vmxnet3_rq_cleanup_all, which could also lead to a kernel information leak problem.
