On Feb 15, 2023, the following vulnerability in the ClamAV scanning library was disclosed: A vulnerability in the DMG file parser of ClamAV versions 1.0.0 and earlier, 0.105.1 and earlier, and 0.103.7 and earlier could allow an unauthenticated, remote attacker to access sensitive information on an affected device. This vulnerability is due to enabling XML entity substitution that may result in XML external entity injection. An attacker could exploit this vulnerability by submitting a crafted DMG file to be scanned by ClamAV on an affected device. A successful exploit could allow the attacker to leak bytes from any file that may be read by the ClamAV scanning process.

IBM HTTP Server 8.5 used by IBM WebSphere Application Server could allow a remote user to cause a denial of service using a specially crafted URL. IBM X-Force ID: 248296.

As more businesses shift away from running workloads on dedicated virtual machines to running them inside containers using workload orchestrators like Kubernetes, adversaries have become more interested in them as targets. Moreover, the benefits Kubernetes provides for managing workloads are also extended to adversaries. As adversaries leverage Kubernetes to run their workloads, their understanding of how these platforms work and can be exploited increases.

In nf_tables_updtable, if nf_tables_table_enable returns an error, nft_trans_destroy is called to free the transaction object. nft_trans_destroy() calls list_del(), but the transaction was never placed on a list -- the list head is all zeroes, this results in a NULL pointer dereference.

Active IQ Unified Manager for VMware vSphere, Linux, and Microsoft Windows versions prior to 9.11P1 are susceptible to a vulnerability which allows administrative users to perform a Stored Cross-Site Scripting (XSS) attack.

The framework-as-a-service signals an intensification of the cat-and-mouse game between defenders detecting lateral movement, and cybercriminals looking to go unnoticed.

In the Linux kernel before 6.0.3, drivers/gpu/drm/virtio/virtgpu_object.c misinterprets the drm_gem_shmem_get_sg_table return value (expects it to be NULL in the error case, whereas it is actually an error pointer).
